Blazing meteorites from the outer solar system triggered life on Earth 4.6 billion years ago

Great balls of fire! Blazing meteorites from the outer regions of the solar system triggered life on Earth 4.6 billion years ago

Great balls of fire from the outer regions of the solar system brought the building blocks of life to Earth 4.6 billion years ago, a new study reveals.

Scientists at the Massachusetts Institute of Technology and Imperial College London found these ancient meteorites contained carbonaceous chondrite, which consisted of potassium and zinc.

Potassium helps produce a cell’s fluids, while zinc is vital in creating DNA.

The team found that these space rocks made up ten percent of the space rocks that smashed into the planet during its birth.

The other 90 percent came from the inner solar system’s non-carbonaceous (NC) material. 

Life of Earth was triggered by fireballs that collided with the newly birthed planet 4.6 billion years ago

‘Our studies complement and confirm each other’s results in multiple ways,’ the study’s lead author Dr Nicole Nie told SWS.

‘Among moderately volatile elements, potassium is the least volatile while zinc is one of the most volatile elements.’

The meteorites provided 20 percent of Earth’s potassium and half its zinc.

Both are considered volatiles, which are elements or compounds that change from a solid or liquid state into vapor at relatively low temperatures.

Senior author Professor Mark Rehkämper, of Imperial College London’s Department of Earth Science and Engineering, said in a statement: ‘Our data show that about half of Earth’s zinc inventory was delivered by material from the outer Solar System, beyond the orbit of Jupiter. 

‘Based on current models of early Solar System development, this was completely unexpected.’ 

Previous research suggested that the Earth formed almost exclusively from inner Solar System material, which researchers inferred was the predominant source of Earth’s volatile chemicals.

However, the new study provides the first evidence that Earth formed partly from carbonaceous meteorites from asteroids in the outer main belt. 

‘This contribution of outer Solar System material played a vital role in establishing the Earth’s inventory of volatile chemicals,’ said Rehkämper.

‘It looks as though without the contribution of outer Solar System material, the Earth would have a much lower amount of volatiles than we know it today – making it drier and potentially unable to nourish and sustain life.’ 

The team analyzed 18 meteorites,11 from the inner region and the rest traveled from the outer areas.

The meteorites contained potassium and zinc and traveled from the outer regions of the solar system

And then, they measured the relative abundances of zinc’s five different forms – or isotopes. 

They then compared each isotopic fingerprint with Earth samples to estimate how much these materials contributed to the Earth’s zinc inventory, showing that Earth only incorporated about ten percent of its mass from carbonaceous bodies. 

 The researchers found that material with a high concentration of zinc and other volatile constituents is also likely to be relatively abundant in water, giving clues about the origin of Earth’s water.

Scientists reveal what was behind mysterious radio signal sent from 9 billion light years away

Scientists have detected a mysterious radio wave which started almost nine billion light-years away from Earth.

But before you get excited, this is not a sign that aliens are trying to contact us from another corner of the universe.

Instead, cosmologists from the Indian Institute of Science and McGill University say that the signal was emitted from a star-forming galaxy 8.8 billion years ago.

Properties of the signal indicate that it came from gaseous hydrogen in a faraway galaxy named ‘SDSSJ0826+5630’.

Scientists have detected a mysterious radio wave which started life almost nine billion light-years away from Earth. Pictured: Image of the radio signal from galaxy SDSSJ0826+5630

The radio wave in question was picked up by the Giant Metrewave Radio Telescope in Pune (pictured), India, and had a wavelength of 48 cm 

WHAT IS ‘REDSHIFT’? 

As radiation travels across expanding space, its wavelength is stretched and frequency reduced, through what is known as ‘redshift’.

The magnitude of the redshift allows scientists to calculate when the waves was emitted.

‘It’s the equivalent to a look-back in time of 8.8 billion years,’ said Dr Arnab Chakraborty from McGill University.

Hydrogen is of great interest to physicists as it is the simplest element and one of the key building blocks of the universe.

After the Big Bang, around 13.8 billion years ago, hydrogen was spread throughout the universe as a fog from which the first stars and galaxies formed.

Scientists are always looking out for  waves that can be traced back to this early hydrogen, to discover more about the creation of the universe.

The radio wave in question was picked up by the Giant Metrewave Radio Telescope in Pune, India, and had a wavelength of 48 cm.

However, the researchers from Montreal, Canada and Bangalore, India deduced that this particular radio signal actually started life with a wavelength of 21 cm.

Neutral hydrogen atoms emit waves with a characteristic wavelength of 21 cm and frequency of 1420 MHz.

This enables them to penetrate dust clouds and cover great distances across the universe, where eventually some of them are detected by Earth-bound scientists.

But as this radiation travels across expanding space, its wavelength is stretched and frequency reduced, through what is known as ‘redshift’.

Redshift allows scientists to calculate how long ago the wave was emitted which, in this case, was when our galaxy was just 4.9 billion years old.

Gravitational lensing is where the gravity of a massive object causes the magnification of electromagnetic radiation.  Massive objects like galaxies cause space-time to bend around it, and if they are on the path of rays of light, the rays will be forced to take different paths to bend around it too. The rays then converge on the other side as a single, focused ray

WHAT IS ‘GRAVITATIONAL LENSING’? 

Gravitational lensing is where the gravity of a massive object causes the magnification of electromagnetic radiation.

Albert Einstein’s theory of relativity states that gravity is not a force, but a warping of space-time as a result of the presence of mass or energy.

If you think of a stretched-out sheet as space-time, and a melon as a representation of mass, dropping the melon on the sheet will cause the latter to curve around it.

As a result, objects with less mass move towards the densest object on this curve, manifesting as a gravitational pull. 

Light is also affected by this curvature, as a massive object in its path causes each ray to take a different path and bend around it.

All the rays then converge into a focused point on the other side of the object as a single, magnified ray which is more easily detectable by telescopes.

Signs of hydrogen in the outer reaches of the universe are notoriously hard to come by.

The waves hydrogen atoms produce often have long wavelengths are are low in energy, making them unlikely to survive the long journey to our telescopes.

Up until now, the oldest hydrogen emission ever detected was 4.4 billion years old.

But this latest signal benefited from a phenomenon called ‘gravitational lensing’, which focused the rays and allowed for their detection.

Albert Einstein’s theory of relativity states that gravity is not a force, but a warping of space-time as a result of the presence of mass or energy.

If you think of a stretched-out sheet as space-time, and a melon as a representation of mass, dropping the melon on the sheet will cause the latter to curve around it.

As a result, objects with less mass move towards the denser object on this curve, manifesting as a gravitational pull. 

The more massive the object, for example a star, black hole or galaxy, the more space-time is warped and the stronger its gravitational pull. 

Light is also affected by this curvature, as a massive object in its path causes each ray to take a different path and bend around it. 

All the rays then converge into a single, focused ray on the other side of the object which is more easily to detect with telescopes.

Co-author Dr Nirupam Roy, from the Indian Institute of Science, said: ‘Gravitational lensing magnifies the signal coming from a distant object to help us peer into the early universe. 

Co-author Dr Nirupam Roy said: ‘In this specific case, the signal is bent by the presence of another massive body, another galaxy, between the target and the observer. This effectively results in the magnification of the signal by a factor of 30, allowing the telescope to pick it up.’ Pictured: Image of foreground galaxy taken by the Hubble Space Telescope which magnified the light from SDSSJ0826+5630

‘In this specific case, the signal is bent by the presence of another massive body, another galaxy, between the target and the observer. 

‘This effectively results in the magnification of the signal by a factor of 30, allowing the telescope to pick it up.’

The physicists were able to glean information about the hydrogen gas in the source galaxy from the signal.

In their paper, published this month in Monthly Notices of the Royal Astronomical Society, they say that the atomic mass of gas in SDSSJ0826+5630 is nearly double that of the stars visible from Earth.

They also hope that the discovery of such an old hydrogen emission means that more could be on the horizon, and result in a better understanding of the universe.

‘A galaxy emits different kinds of radio signals,’ said Dr Chakraborty.

‘Until now, it’s only been possible to capture this particular signal from a galaxy nearby, limiting our knowledge to those galaxies closer to Earth.

‘But thanks to the help of a naturally occurring phenomenon called gravitational lensing, we can capture a faint signal from a record-breaking distance. 

‘This will help us understand the composition of galaxies at much greater distances from Earth.’

Aliens haven’t contacted Earth yet because there’s no sign of intelligence here, study claims 

If aliens really do exist, why haven’t they already tried to contact us?

The idea of intelligent extraterrestrial life has long gripped scientists and the public alike, with a multitude of theories about what may or may not be out there in the depths of space.

A recent study has now put forward a new explanation for why aliens haven’t visited our planet – because there is no sign of intelligence here.

In essence, they mean that we have only been sending out signals detectable from space since the 1930s, so extraterrestrials haven’t really had that long to receive the message or reply to it.

MIT’s 10 breakthrough technologies for 2023: Abortion pills via telehealth and engineered organs

Engineered organs that could end transplant waiting lists, abortion pills on demand and mass-marketing military drones that will revolutionize warfare are among those listed on MIT Technology Review’s 10 Breakthrough Technologies of 2023.

The list also includes the use of CRISPR to edit away people’s problems with high cholesterol by rewriting a sliver of their DNA, artificial intelligence that makes artwork and NASA’s James Webb Space Telescope, which is set to remodel our knowledge of the cosmos. 

The 22nd annual list features critical technological advances predicted to change how we live and work fundamentally. 

MIT Technology Review, owned by the Massachusetts Institute of Technology, compiled the list of companies or institutions set to develop breakthroughs and when the public can expect these innovations.

MIT Technology Review announced its 10 Breakthrough Technologies of 2023, which are advanced technologies predicted to change our lives

Mat Honan, editor-in-chief of MIT Technology Review, said: ‘Our breakthrough technologies lists are fascinating snapshots of the evolution of big tech innovation breakthroughs. 

‘They document the progress we have made in many of the core areas at the intersection of science and engineering. Inclusion is not an endorsement as much as it is a statement about the potential impact of a technology. 

‘Some of my favorite picks on the list this year are the ones that inspire a sense of awe and wonder at the scope of human achievement.’

CRISPR for high cholesterol: Editing genes to save lives

The list includes the use of CRISPR to edit away people’s problems with high cholesterol by rewriting a sliver of their DNA. In July 2022, a patient in New Zealand received a gene-editing medicine (pictured) that permanently lowered her cholesterol

Artificial intelligence is a major technology and is being used to create stunning pieces of artwork

WHO: Verve Therapeutics, Beam Therapeutics, Prime Medicine, Broad Institute 

WHEN: 10 to 15 years

In July 2022, a patient in New Zealand received a gene-editing medicine that permanently lowered her cholesterol.

The move led to a trial among 40 individuals from the UK and the US, who are now testing ‘Verve-101.’

The cholesterol-lowering treatment, developed by Verve Therapeutics, relies on a form of gene editing called base editing, or ‘CRISPR 2.0.’ 

Verve-101 deletes a tiny hereditary flaw that causes life-threatening amounts of fatty substances in the blood.

In November, a team of scientists led University of California, Los Angeles, announced they had tailored DNA-editing technology to turbocharge how the body fights cancer cells.

These systems are given simple instructions on what the creator wants via text. Tools like DALL-E and Midjourney, for example, can create everything from absurd hypotheticals and porn to realistic faces of fake people and self-portraits in a matter of seconds

They modified patients’ genes to instruct cancer-fighting cells to swarm tumors using CRISPR, administered as a one-off injection.

Then there is the lasted form of CRISPR, ‘CRISPR 3.0,’ which lets scientists insert pieces of DNA into a genome, which could allow them to replace disease-causing genes.

AI that makes images: Systems create stunning images from simple phrases

WHO: OpenAI, Stability AI, Midjourney, Google 

WHEN: Now

OpenAI released its original version of DALL-E, named after Spanish surrealist artist Salvador Dali, and Pixar robot WALL-E, in January 2021.

This system launched as a limited test of ways AI could represent concepts – from boring descriptions to flights of fancy.

And a year later, OpenAi released DALL-E 2, which produces complete images from a simple plain English sentence.

The new version can create images from simple text, add objects to existing images, or even provide different points of view on an existing image. 

MIT Technology Review notes that ‘the biggest game-changer was Stable Diffusion, an open-source text-to-image model released for free by UK-based startup Stability AI in August.

This system also produces stunning images, but is designed to run on a home computer rather than a professional device.

‘By making text-to-image models accessible to all, Stability AI poured fuel on what was already an inferno of creativity and innovation,’ according to MIT Technology Review.

While many might not thing chips are advancing, the standard at which they are made is. The open standard known as RISC-V simplifies instructions given to the processor to accomplish tasks and provides the flexibility to create thousands

‘Millions of people have created tens of millions of images in just a few months. But there are problems, too.’

Google has long been in the AI industry but is making a stronger push to stay relevant. 

The tech giant released AI-generated video clips that looked like human hands made them. 

A chip design that changes everything: New standards will let anyone create chips

WHO: RISC-V International, Intel, SiFive, SemiFive, China RISC-V Industry Alliance

WHEN: Now

Computer chip designs are expensive and hard to license. 

That is all about to change thanks to the popular open standard known as RISC-V, which simplifies the instructions given to the processor to accomplish tasks and provides the flexibility to create thousands of possible custom processors.

This new standard would also speed up the process for companies to get their products to market. 

RISC-V’s simplest design has just 47 instructions. But RISC-V also offers other design norms for companies seeking chips with more complex capabilities.

America has long been the leader in using drones on the battlefield. This is due to its Predator (pictured)  that was conceived in the early 1990s and cost around $40 million

Technologies are advancing to allow other countries to create war drones at a lower cost. For example, Iran produced a $30,000 drone capable of long-range missions that Russia used (pictured) 

‘About 3,100 members worldwide, including companies and academic institutions, are now collaborating via the nonprofit RISC-V International to establish and develop these norms,’ according to MIT Technology Review.

‘In February 2022, Intel announced a $1 billion fund that will, in part, support companies building RISC-V chips.’

Although slowly, these chips are currently being used and are found in earbuds, hard drives and AI processors.

Mass-market military drones: Providing drones at a lower price will change the way wars are fought

WHO: Baykar Technologies, Shahed Aviation Industries

WHEN: Now

America has long been the leader in using drones on the battlefield.

This is due to the nation’s Predator which was conceived in the early 1990s and cost around $40 million.

With the news of the US Supreme Court ruling to overturn Roe v. Wade on June 24, 2022, medical experts set out to provide care to those in states where abortion is now banned  by shipping abortion pills to their homes

One reason for the dominance is that the US has the funds for such technologies.

However, MIT Technology Review notes that the game has changed, and military drones are being produced at a lower price, allowing nations like Ukraine, Iran and Turkey to utilize the weapons.

For example, Iran produced a $30,000 drone capable of long-range missions, while Turkey produced its own for $5 million. 

‘The tactical advantages are clear. What’s also sadly clear is that these weapons will take an increasingly horrible toll on civilian populations around the world,’ reads the report.

Abortion pills via telehealth: A new market emerges after the overturn of Roe v. Wade   

WHO: Choix, Hey Jane, Aid Access, Just the Pill, Abortion on Demand, Planned Parenthood, Plan C

WHEN: Now

Medical treatment was transformed when the coronavirus pandemic gripped the US. 

People could get treatment using a smartphone or computer in the comfort of their homes.

And with the news of the US Supreme Court ruling to overturn Roe v. Wade on June 24, 2022, medical experts set out to provide care to those in states where abortion is now banned. The procedure is illegal in 11 states.

Nonprofits like Aid Access and startups like Choix, Hey Jane and  Just the Pill launched in what like seemed overnight.

Organs on demand is another on MIT’s list. This innovation could save hundreds of thousands of lives.  Terminal heart failure sufferer David Bennett underwent the nine-hour experimental procedure where he received a heart transplant from a genetically-modified pig

In 2019, researchers in Germany created transparent human organs using a new technology that could pave the way to print three-dimensional body parts such as kidneys for transplants

These companies ship abortion pills to people’s homes after they sign up with a photo ID and consult with a medical provider via video call, text or an app, who then prescribes the pills.

 And while abortion is illegal in nearly a dozen states, this month, the Food and Drug Administration (FDA) approved online and brick-and-mortar retail pharmacies to dispense abortion pills to patients who have a prescription – regardless of their location.

Organs on demand: Gene-editing animal organs, 3D printing organs and growing organs in a lab to save human lives

WHO: eGenesis, Makana Therapeutics, United Therapeutics

WHEN: 10 to 15 years 

More than 106,000 people in the US are waiting for an organ transplant, and science is stepping in to create organs to help save lives.

In 2019, researchers in Germany created transparent human organs using a new technology that could pave the way to print three-dimensional body parts such as kidneys for transplants.

Scientists led by Ali Erturk at Ludwig Maximilians University in Munich have developed a technique that uses a solvent to make organs such as the brain and kidneys transparent.

Electric vehicles are here to stay, and Tesla is leading the pack. The world’s roads saw about 16.5 million EVs cruising in 2022, triple the amount in 2018, and global sales were up by 75 percent from the same period in 2022

However, Tesla has competition. MIT notes Hyundai’s IONIQ 5 that was announced last year

Lasers then scan the organ in a microscope that allows researchers to capture the entire structure, including the blood vessels and every single cell in its specific location.

Another method is genetically modifying animal organs, which the world witnessed in January 2022.

Terminal heart failure sufferer David Bennett underwent the nine-hour experimental procedure at the University of Maryland Medical Center in Baltimore, where he received a heart transplant from a genetically-modified pig.

Surgeons used a heart taken from a pig that had undergone gene editing to make it less likely that his body’s immune system would reject the organ. 

The inevitable EV: Electric vehicles have been available for decades. Now they’ve finally become mainstream

WHO: BYD, Hyundai, Tesla, Volkswagen

WHEN: Now 

Electric vehicles have made waves in the automobile industry, as many nations are phasing out gas-powered cars for greener versions.

The world’s roads saw about 16.5 million EVs cruising in 2022, triple the amount in 2018, and global sales were up by 75 percent from the same period in 2022.

The largest player is Elon Musk’s Tesla, which has held most of the market since it sold the first Model S sedan in 2012.

NASA’s James Webb Space Telescope is set to change what we know about the cosmos and is revealing what the early universe looked like. Here is an image of a 13.5-billion-year-old galaxy

However, Tesla has been joined by Volkswagen and Hyundai, among others like Ford, which are planning to overtake Musk’s company.

Herbert Diess, the current chairman of the board of management of Volkswagen Group, said the German company is looking to surpass Tesla by 2025. 

VW sold 452,900 EVs worldwide in 2021, while Tesla sold 930,422. 

Hyundai recently gained popularity with its IONIQ 5 for $72,000, which was named Carsales Car of the Year for 2021.

The IONIQ 5 is the first electric vehicle to win the Carsales prize since the Tesla Model S was named Car of the Year in 2015 and was one of three fully electric cars on the Carsales 2021 shortlist of 12 models. 

James Webb Space Telescope: A marvel of precision engineering that could revolutionize our view of the early universe

WHO: NASA, European Space Agency, Canadian Space Agency, Space Telescope Science Institute

WHEN: Now

The world is also seeing never-before-images of stars forming in deep space

The James Webb Space Telescope, launched December 25, 2021, spent the last year wowing the world with amazing never-before-seen pictures of the cosmos.

Developed by NASA, the $10 billion telescope is a collaboration between the US, Europe and Canada.

Webb is the world’s largest and most powerful orbital space telescope, capable of peering back 100 to 200 million years after the big bang.

The orbiting infrared observatory is designed to be about 100 times more powerful than its predecessor, the Hubble Space Telescope.

NASA likes to think of James Webb as a successor to Hubble rather than a replacement.

Webb has shared images of galaxies that formed 13.5 billion years ago, just 300 million years after the big bang, the first photos of stars formed and recently identified a previously unknown planet.

Ancient DNA analysis: Provides scientists with a time machine to see the past

Ancient DNA analysis provides scientists with a trip back in time to learn about early humans. Scientists analyzed DNA from 4,000-year-old mummies found in China and found the individuals were from a local tribe, not visitors from the West as previously believed

 Ernie Lapointe (right) made headlines in 2021 when his DNA matched the famed Native American Sitting Bull (left)

A man made headlines in 2021 when his DNA matched the famed Native American Sitting Bull.

University of Cambridge-led experts demonstrated the technique known as ‘autosomal DNA’ that collected DNA from a strand of hair taken from Sitting Bull and pulled DNA from it. 

The team then matched the DNA with Ernie Lapointe, confirming he is the great-grandson of the Native American leader. 

Going back in time, scientists analyzed DNA from 4,000-year-old mummies found in China and found the individuals were from a local tribe, not visitors from the West as previously believed.

The team compared the mummies’ DNA with samples from five individuals who lived further north in the Dzungarian Basin about 5,000 years ago, making them the oldest known human remains in the region. 

Battery recycling: New ways to recover the crucial metals in batteries could make electric vehicles more affordable

WHO: CATL, Umicore, Redwood Materials, Li-Cycle, Cirba

WHEN: Now 

Battery recycling is seeing a boom as the world moves away from gas-powered vehicles and toward zero-emission versions

Batteries used in electric cars, laptops and other electronics have long been tossed in landfills because there is no method for recycling.

Battery recycling is an effective way of reprocessing and reusing batteries to reduce wastage. 

It prevents the potential threat surfacing from dumping heavy metals and toxic chemicals into the environment. 

In 2022, the market value shot up to $15.81 billion and is predicted to reach a whopping $36 billion in 2028. 

CATL announced a $5 billion battery recycling center in China last year to recycle EV batteries for chemicals such as cobalt and lithium. 

Umicore has a plant in Belgium with an annual capacity of 7,000 lithium-ion batteries and battery production scrap, equivalent to 35,000 EV batteries.

The plant started operations in 2011 to treat portable electronic batteries and the first generations of EV batteries.

The recovered metals will be delivered in battery-grade quality at the end of the Umicore recycling process, allowing them to be re-circulated into the production of new Li-ion batteries.

These facilities are also likely to appear worldwide as nations are adopting EVs to combat climate change, making zero-emission cars cheaper because there would be more materials available.

Does Planet X really exist?

It has been six years since astronomers found strong evidence that a mysterious ninth planet might exist at the far reaches of our solar system.

But the so-called theoretical world – dubbed Planet X – has still not actually been seen by anyone, and for the meantime remains just that, a theory.

If it is real, scientists say it could have a mass about 10 times that of Earth and may take between 10,000 and 20,000 years to make one full orbit around the sun. 

The reason they think Planet X is there is because they can see other objects in space being affected by it. So are they any closer to solving the mystery? MailOnline looks at where the world of astronomy currently sits on the issue.

Peculiar: It has been six years since astronomers found strong evidence that a ninth planet might exist at the far reaches of our solar system. So are they any closer to solving the mystery of Planet X? MailOnline looks at where the world of astronomy currently sits on the issue

What is so mysterious about Planet X?

Planet X, or Planet Nine as it has also been called, is a theoretical planet that some astronomers think could be hiding at the very edge of our solar system.

The reason they think this is because the orbits of a number of bodies in the distant reaches of our solar system have been disrupted by the pull of something, most likely an as yet unidentified ninth planet.

The problem is, no one has actually seen this potential world — its existence is based purely on mathematics.

There are many things fascinating about this possible Planet X, but chief among them is that its hypothetical orbit would see it take between 10,000 and 20,000 years to make a single pass around the sun. Pictured is how this orbit would compare to the other eight planets

In 2015, Caltech astronomers Konstantin Batygin and Mike Brown announced new research which provided impelling evidence of a giant planet tracing an unusual, elongated orbit in the outer solar system.

If it does exist, the data and computer modelling suggests that Planet X would need to be roughly four times the size of Earth and ten times its mass. 

The theory goes that a body of this size and mass would explain the clustered paths of some smaller objects in the Kuiper Belt, a distant region of icy debris that extends far beyond the orbit of Neptune.

There are many things fascinating about this possible world, but chief among them is that its hypothetical orbit would see it take between 10,000 and 20,000 years to make a single pass around the sun.

Neptune completes an orbit roughly every 165 years. 

Who first came up with the idea of a ninth planet?

WHO WAS PERCIVAL LOWELL?

Percival Lowell

A 19th Century travel writer and businessman, Percival Lowell decided to become an astronomer after reading a book on Mars.

He founded the Lowell Observatory in Flagstaff, Arizona, in 1894, before studying the Red Planet religiously and making in intricate drawings of the surface markings as he perceived them. 

Lowell was convinced that the Red Planet sustained intelligent life forms. So much so that he believed that strange lines had had observed on the Martian surface were canals, built as the last attempt of a dying civilisation to tap water from the polar ice caps. 

He also wrongly believed that Venus had spokes emanating from its centre.

The last proper planet to be discovered was Neptune in 1846. However, at the time there was a lot of speculation that it might not be the last, and that another world might still exist deep beyond its orbit.

Step up 19th Century travel writer and businessman Percival Lowell.

Lowell is remembered for a series of outlandish theories about space, having decided to become an astronomer after reading a book on Mars.

Lowell was convinced that the Red Planet sustained intelligent life forms. So much so that he believed that strange lines had had observed on the Martian surface were canals, built as the last attempt of a dying civilisation to tap water from the polar ice caps. 

Most importantly, however, Lowell was convinced there was a ninth planet in our solar system.

He died at the age of 61 in 1961, without ever figuring out whether his theory was true, but left a million dollars in his will to go towards finding Planet X.

Lowell’s observatory kept looking and 14 years later, on 18 February 1930, a young astronomer looking at two photos noticed what turned out to be a tiny world known as Pluto.

This was mistakenly considered to be the mysterious Planet X. 

Ultimately, Pluto would lose its planet status anyway, being downgraded to a dwarf planet in 2006, along with what was initially described as the solar system’s tenth planet, Eris, discovered in 2005.

Now, Planet X is a general term for any undiscovered planet in the solar system. 

But the idea of Planet X was briefly dismissed?

Yes, by one of the Voyager spacecraft in 1989. 

When Voyager 2 raced past Neptune it revealed that the planet was fractionally lighter than anyone had originally thought. 

This led a NASA scientist to calculate that the orbits of the outer planets had made sense all along.

The mystery, it seemed, was closed. Planet X was not Pluto, not Eris, and it did not exist. 

So why did its existence spring up again?

Primarily because of the Caltech astronomers Batygin and Brown.

Eight years ago they shared detailed mathematical modelling and computer simulations which hinted that a large object was to blamed for the unique orbits of at least five smaller objects discovered in the distant Kuiper Belt.

Breakthrough: In 2015, Caltech astronomers Mike Brown (left) and Konstantin Batygin (right) announced new research which provided impelling evidence of a giant planet tracing an unusual, elongated orbit in the outer solar system

‘The possibility of a new planet is certainly an exciting one for me as a planetary scientist and for all of us,’ Jim Green, director of NASA’s Planetary Science Division, said at the time.

‘This is not, however, the detection or discovery of a new planet. It’s too early to say with certainty there’s a so-called Planet X. 

‘What we’re seeing is an early prediction based on modelling from limited observations. It’s the start of a process that could lead to an exciting result.’

What other theories are there?

It’s actually just a tiny black hole.  

That’s according to physicists Jakub Scholtz and James Unwin, who claimed it would be so small that it would be the size of a bowling ball.

They made the suggestion in 2019, on the basis that a black hole could be equally as responsible as a planet for affecting the orbits of a series of rocky objects that circle Neptune.

Much like with Planet X, which some astronomers believe was a free-floating planet that was booted out of its original star system and began orbiting our sun after flying close to the solar system, Scholtz and Unwin said the same could apply to a mini black hole.

In 2020, a new theory was published in The Astrophysical Journal Letters by scientists from Harvard University which suggested that not only might Planet X actually exist but that there may once have been a binary companion to our sun.

‘Dr. Avi Loeb, Frank B. Baird Jr. Professor of Science at Harvard, and Amir Siraj, a Harvard undergraduate student, have postulated that the existence of a long-lost stellar binary companion in the sun’s birth cluster — the collection of stars that formed together with the sun from the same dense cloud of molecular gas — could explain the formation of the Oort cloud as we observe it today,’ the authors wrote.

The Oort Cloud is believed to be a giant spherical shell surrounding the sun, planets, and Kuiper Belt Objects containing billions, or trillions of icy pieces of space debris left over from the formation of the solar system. 

It is believed to be the source of long-period comets.

Is Planet Nibiru the same as Planet X?

No.

Nibiru, sometimes also referred to as Planet X, is a different hypothesised planet on the edge of our solar system.

Conspiracy theorists believe the gravitational influence of the ‘rogue planet’ Nibiru disrupted the orbits of other planets hundreds of years ago.

They claim the next disruptive passage into the inner solar system could happen at any time.

Peculiar: Nibiru (pictured in an artist’s impression), sometimes also referred to as Planet X, is a different hypothesised planet on the edge of our solar system

Nibiru is supposedly mentioned on ancient Sumerian clay tablets and is said to have crashed through the early solar system creating the asteroid belt and the Earth before vanishing again.

Some conspiracy theorists claim that this ‘planet’ is sending ‘plasmatic energy particles’ through our solar system.

The flow of energy will disrupt the ‘core flows’ of the Earth and trigger catastrophic changes in Earth’s climate.

They claim, since 1996, we have already been feeling the disruptive effects of the inbound rogue Planet X.

Conspiracy theorists often blame natural disasters and freak weather patterns on the planet.

‘Nibiru and other stories about wayward planets are an internet hoax,’ NASA has said. ‘Obviously, it does not exist.’

So where are scientists with solving the mystery of Planet X now?

They haven’t got there yet, but remain optimistic of doing so.

Eighteen months ago Mike Brown said: ‘I think it’s within a year or two from being found.

But he cautioned: ‘I’ve made that statement every year for the past five years. I am super-optimistic.’

In 2021, the existence of Planet X was dealt a blow when a team led by physicist Kevin Napier, at the University of Michigan in Ann Arbor, examined the orbits of ‘extreme’ trans-Neptunian objects. 

The researchers found that the objects’ perturbed orbits could actually be explained without the presence of a nearby planet.

They concluded that the objects only seem to have clustered paths because of selection bias, although many others disagree and say more data is needed. 

There may be an answer either way soon, however.  

The Vera C. Rubin Observatory (VRO) in Chile, which came online in 2021, began a ten-year survey of the sky last year which is expected to detect thousands more Kuiper belt objects.

A close examination of their orbits may be able to confirm or deny the existence of Planet X and provide clues as to its origin and location.

Harvard’s Dr Avi Loeb said: ‘If the VRO verifies the existence of Planet Nine, and a captured origin, and also finds a population of similarly captured dwarf planets, then the binary model will be favoured over the lone stellar history that has been long-assumed.’

WHAT IS THE KUIPER BELT?

 The Kuiper Belt is one of the largest structures in our solar system – others being the Oort Cloud, the heliosphere and the magnetosphere of Jupiter. 

Scientists are still just beginning to explore and our understanding is still evolving. 

Its overall shape is like a puffed-up disk, or donut. Its inner edge begins at the orbit of Neptune, at about 30 AU from the Sun.

The inner, main region of the Kuiper belt ends to around 50 AU from the Sun. 

Overlapping the outer edge of the main part of the Kuiper Belt is a second region called the scattered disk, which continues outward to nearly 1,000 AU, with some bodies on orbits that go even farther beyond.  

 How was the Kuiper Belt created?

Astronomers think the icy objects of the Kuiper Belt are remnants left over from the formation of the solar system. 

Similar to the relationship between the main asteroid belt and Jupiter, it’s a region of objects that might have come together to form a planet had Neptune not been there. 

nstead, Neptune’s gravity stirred up this region of space so much that the small, icy objects there weren’t able to coalesce into a large planet.

Visibility of stars at night is DECLINING by 10% per year thanks to light pollution, study warns

Stargazing could soon become a thing of the past: Visibility of stars in the night sky is DECLINING by 10% per year thanks to light pollution, study warns

  • Researchers evaluated 51,351 star observations seen between 2011 and 2022
  • The night sky has increased in brightness from artificial light by 7 to 10% per year
  • This is equivalent to a doubling of the night sky’s brightness in less than 8 years

There’s something quite awe-inspiring in looking at the night sky and seeing distant stars twinkling back at you.

From the glowing arc of the Milky Way to dozens of intricate constellations, the human eye should be able to see several thousand stars on a clear, dark night.

But in bad news for stargazers the spectacular sight is ‘vanishing’ due to increasing levels of light pollution, according to a new study.

Observations of the night sky over the past 12 years reveal the change in visibility is equivalent to a 9.6 per cent increase in sky brightness per year.

Observations of the night sky over the past 12 years reveal the change in visibility is equivalent to a 9.6 per cent increase in sky brightness per year

To put this in perspective, the authors say a child born in an area where 250 stars were visible would likely see fewer than 100 stars in the same location 18 years later.

Researchers evaluated 51,351 citizen scientist observations of stars seen with the naked eye between 2011 and 2022.

To determine the brightness of the night sky, they asked participants across the world to compare star maps to what they could see with their own eyes.

According to the findings, the night sky has increased in brightness from artificial light by roughly 7 to 10 per cent per year.

This is the equivalent to a doubling of the night sky’s brightness in less than eight years, they said.

Astronaut photographs of parts of Calgary show examples of how lighting changed from 2010-2021: New lighting has been installed and many streetlights have been converted from orange high pressure sodium to white LED

And it is much greater than the data provided by satellites, which suggest the night sky has increased in brightness by roughly 2 per cent per year.

When the researchers specifically looked at Europe, they found an increase in brightness of 6.5 per cent per year. 

The research, published in the journal Science, was carried out by teams from the German Research Centre for Geosciences and the National Science Foundation (NSF) in the US.

Connie Walker, from NSF, said: ‘The increase in skyglow over the past decade underscores the importance of redoubling our efforts and developing new strategies to protect dark skies.’

Commenting on the study David Rothery, Professor of Planetary Geosciences at The Open University, said local councils should take action to help reduce light pollution in the UK.

‘Light pollution is a serious issue, not just for those of us who like to be able to see the stars, but for wildlife too,’ he said.

‘It is also a waste of electricity – and money – and therefore makes climate change targets harder to achieve.

‘Local councils could take action here. They should revoke permissions for illuminated name and logo signs on industrial units that are currently turned on throughout the night.

‘They should require industrial and domestic security lights to have screens that direct the light downwards onto the owner’s property only, rather than wasting half of it across the neighbourhood.

‘Perhaps with the cost of electricity currently so high, people will wise up and begin save money by illuminating only what they need.’

LIGHT POLLUTION IS ARTIFICIAL LIGHT THAT IS EXCESSIVE, OBTRUSIVE AND WASTEFUL

Light pollution, also known as photopollution, is the presence of anthropogenic light in the night environment. 

Artificial light that’s excessive, obtrusive and ultimately wasteful is called light pollution, and it directly influences how bright our night skies appear. 

With more than nine million streetlamps and 27 million offices, factories, warehouses and homes in the UK, the quantity of light we cast into the sky is vast. 

While some light escapes into space, the rest is scattered by molecules in the atmosphere making it difficult to see the stars against the night sky. What you see instead is ‘Skyglow’.

The increasing number of people living on earth and the corresponding increase in inappropriate and unshielded outdoor lighting has resulted in light pollution—a brightening night sky that has obliterated the stars for much of the world’s population. 

Most people must travel far from home, away from the glow of artificial lighting, to experience the awe-inspiring expanse of the Milky Way as our ancestors once knew it.

Light pollution is excessive and inappropriate artificial light. While some light escapes into space, the rest is scattered by molecules in the atmosphere making it difficult to see the stars against the night sky. What you see instead is ‘Skyglow’

The negative effects of the loss of this inspirational natural resource might seem intangible. 

But a growing body of evidence links the brightening night sky directly to measurable negative impacts on human health and immune function, on adverse behavioural changes in insect and animal populations, and on a decrease of both ambient quality and safety in our nighttime environment.

Astronomers were among the first to record the negative impacts of wasted lighting on scientific research, but for all of us, the adverse economic and environmental impacts of wasted energy are apparent in everything from the monthly electric bill to global warming.

Scientists reveal the surprisingly simple task that could reignite the spark in your relationship 

When you’ve been with someone for many years, it’s all too easy to let life get in the way and the spark fizzle out.

But, psychologists at the University of Missouri–St. Louis in the US have discovered a surprisingly easy way to reignite the passion, and all you need is a photo.

A study has found that looking at pictures of your partner for just a few seconds can boost feelings of infatuation, attachment and marital satisfaction.

‘Looking at spouse pictures is an easy strategy that could be used to stabilise marriages in which the main problem is the decline of love feelings over time,’ the authors wrote.

A study has found that looking at pictures of your partner for just a few seconds can boost feelings of infatuation, attachment and marital satisfaction (stock image)

Level of infatuation (A), attachment (B) and marital satisfaction (C) of participants while viewing the pictures and statements. Viewing images of the spouse produces the highest levels in all categories, and a preceding positive statement made no difference

There’s nothing quite like the butterflies you feel at the start of a new relationship, but keeping them alive over the years isn’t always easy.

A sad, oft-quoted, statistic is that 42 per cent of marriages in the UK end in divorce, and this year divorce rates are predicted to hit a 50-year high.

Married couples fall out of love for a whole host of reasons, the most common reason being ‘unreasonable behaviour’ in 2021. 

However, the researchers wanted to see if there was an easy way to help couples in long-term or long-distance relationships rekindle the spark.

This could be through looking at photos of their spouse, reading positive things about them or both. 

For the study, published in the Journal of Psychophysiology, they recruited 25 married people who had known their partners for an average of 11.9 years.

The participants first self-reported information about their marriage duration as well as level of infatuation with and attachment to their spouse.

Participants were presented with a set of 25 photos, where each appeared on a computer screen for one second. Some of these were non-intimate images of their spouse, while others were just ‘pleasant’ or ‘neutral’ images which did not feature their spouse. Before some of these images were displayed, a statement appeared on screen to help regulate the participant’s emotions. During the task, the participants had to use a slider to indicate their level of infatuation with and attachment to their spouse, as well as marital satisfaction. Pictured: Experimental protocol

WHAT DID THE STUDY FIND? 

Study participants were presented with a series of photos – some of these showed their spouse, while others were just ‘pleasant’ or ‘neutral’ images and did not feature their spouse.

Before some of these were displayed, a statement appeared on screen to help the participant feel positively about the forthcoming image.

When not preceded by a statement, participants self-reported the largest increases in infatuation, attachment and marital attachment while looking at images of their spouse, compared to the other image types.

The positive statements did not have an effect on these self-reported indicators for either the spouse or pleasant images.

It was therefore concluded that just having a picture of your partner on your desk or in your wallet increases your love for them.

Next, they were presented with a set of 25 photos, where each appeared on a computer screen for one second.

Some of these were non-intimate images of their spouse – either alone, with them or with others – while others were just ‘pleasant’ or ‘neutral’ images which did not feature their spouse.

Before some of these images were displayed, a statement appeared on screen to help regulate the participant’s emotions.

For example, before seeing a picture of their spouse, they may read ‘Think of one good personality trait of your spouse’ or ‘Think of something sweet your spouse did’.

Or before seeing a generic pleasant image, they may read ‘This man is fulfilling his dream of hang gliding’ or ‘This man is celebrating his 100th birthday’.

The neutral pictures were never preceded by an emotional regulation prompt.

During the task, the participants had to use a slider to indicate their level of infatuation with and attachment to their spouse, as well as marital satisfaction.

They also had their late positive potential (LPP) – a voltage of electrical brain activity which indicates emotional arousal – recorded using electroencephalography.

Using this data, the researchers were able to assess what kind of imagery increases one’s love for their partner, and if the preceding positive statements have an effect.

LPP was amplified the most by the spouse pictures, but only to an intermediate level with the pleasant pictures and minimally with the neutral pictures. However, while the statements increased the LPP with the pleasant pictures, they did not have an effect on this voltage when they preceded the spouse images. Pictured: Average LPP for study participants while viewing the pictures and statements

When not preceded by an emotional regulation statement, participants self-reported the largest increases in infatuation, attachment and marital attachment while looking at images of their spouse, compared to the other image types.

LPP was also amplified the most by the spouse pictures, but only to an intermediate level with the pleasant pictures and minimally with the neutral pictures. 

However, while the statements increased the LPP with the pleasant pictures, they did not have an effect on this voltage when they preceded the spouse images.

They also did not have an effect on the self-reported indicators for either the spouse or pleasant images.

It was therefore concluded that just having a picture of your partner on your desk or in your wallet increases your love for them, at least in the short term. 

The authors wrote: ‘This study indicates that looking at spouse pictures increases love and marital satisfaction, which is not due to increased positive emotions unrelated to the spouse.’ 

Reflecting on memories with an ex can improve your current relationship 

Experts claim that thinking about good times with an ex can make you more satisfied with your current partner. 

Psychologists at the University of Kansas asked volunteers to reflect on nostalgic memories with a former flame. 

This subsequently made them think more positively about their current relationship, as it made them aware of how much they had grown since then. 

In the study, the researchers wrote: ‘Fond nostalgic memories about past relationships remind people of the positivity of romantic relationships. 

‘We found it led to an increase in the perceived quality of current partnerships. These memories can be triggered by an ex-lover’s favourite song or movie.’

NASA’s Lunar Gateway space station will be so tiny that astronauts won’t be able to stand

Orbiting at 250 miles above the Earth, the International Space Station (ISS) has been integral to a bucket load of research over the past 25 years.

Surrounded by a dizzying number of controls and experiments, occupants get some shut eye in sleeping bags attached to walls that couldn’t be further from luxury if you tried.

But compared to the upcoming Lunar Gateway space station, which will orbit the moon when it is built later this decade, the ISS is decidedly roomy.

That is according to one of the architects behind the design of Gateway, who said the living quarters will be so small that astronauts won’t be able to stand upright inside them.

Cramped: One of the architects behind the design of the new Lunar Gateway space station says the living quarters will be so small that astronauts won’t be able to stand upright inside them. René Waclavicek said they would total about 280 cubic feet (8 cubic metres), making it smaller than not only the International Space Station but even the average UK living room

LUNAR GATEWAY: THE KEY FACTS

Mass: 40 tonnes

Orbit: Near rectilinear halo

Modules:

– Power and Propulsion Element

– Communications module and connecting module (ESPRIT)

– Science and airlock module 

– Habitat with robotic arm

– Logistics module

René Waclavicek, a space architect and design researcher at Austria-based LIQUIFER Space Systems, said the Lunar Gateway living quarters would total about 280 cubic feet (8 cubic metres), making it smaller than not only the ISS but even the average UK living room.

When Gateway is finished it will be about one sixth of the size of the ISS and feature two habitation modules that will force crew members to exist in very close proximity to each other. 

The space lab’s quarters will be 6ft wide, 6ft long and 6ft high, compared to a 7.2 x 7.2ft interior on the ISS that even allows astronauts to perform space gymnastics routines.

The average UK living room is around 55 cubic feet (17 metres), or 7.5 x 7.5ft.

‘The International Habitation module will have habitable space of about 8 cubic meters [280 cubic feet] and you will have to share it with three others,’ Waclavicek said at the Czech Space Week conference in Brno last November. 

‘In other words, that would be a room 2 by 2 by 2 meters [6.6 by 6.6 by 6.6 feet]. And you are locked in there. 

‘There are other rooms but they are not bigger and there are not many of them.’

When Gateway is finished it will be about one sixth of the size of the ISS and feature two habitation modules that will force crew members to exist in very close proximity to each other 

Who is involved: How Gateway will look and the space organisations involved in building it

That is according to one of the architects behind the design of Gateway, who said the living quarters will be so small that astronauts won’t be able to stand upright inside them 

NASA has said the orbiting laboratory will provide astronauts with a ‘home away from home’ during trips to the moon, and a staging post for lunar landings

WHAT IS THE LUNAR GATEWAY? 

The NASA-led Lunar Gateway is part of a long-term project to send humans to Mars.

The crew-tended spaceport will orbit the moon and serve as a ‘gateway to deep space and the lunar surface,’ the US space agency has said.

The first modules of the station could be completed as soon as 2024.

An international base for lunar exploration for humans and robots and a stopover for spacecraft is a leading contender to succeed the $100 billion International Space Station (ISS), the world’s largest space project to date.

NASA has said the orbiting laboratory will provide astronauts with a ‘home away from home’ during trips to the moon, and a staging post for lunar landings.

The lab will have a four person capacity and will see the US space agency work with some existing ISS partners including Europe, Japan and Canada.

Waclavicek has been involved in the design phase of the European-built International Habitation module, or I-Hab.

It is made up of bedrooms and lab space and is one of Gateway’s two habitable areas, along with the Habitation and Logistics Outpost, or HALO, being developed by US company Northrop Grumman.

Waclavicek said designers initially wanted to make larger modules than the ones on the ISS, with more living space associated with them, but this vision had to be scrapped because it was deemed impossible to launch something as big to the moon.

‘We started off in the first phase with a cylinder with outer dimensions similar to what we know from the ISS,’ Waclavicek said.

‘That’s about 4.5 m [15 feet] in diameter and 6 m [20 feet] long. But due to mass restrictions, we had to shrink it down to 3 m [10 feet] in outer dimensions. 

‘And that left us with an interior cross section of only 1.2 m by 1.2 m [4 feet by 4 feet]. 

‘Most of the internal volume is consumed by machinery, so it’s essentially just a corridor, where you have to turn 90 degrees if you want to stretch out.’

He added: ‘[The I-Hab] really is just a cylinder with a hatch on each end and two hatches at the sides and a corridor going through the length axis. 

‘Even if you want to pass one another, it’s already quite difficult, you have to interrupt whatever you are doing in the moment to let the other fellow pass by you.’

Waclavicek has been involved in the design phase of the European-built International Habitation module, or I-Hab

The space lab’s quarters will be 6ft wide, 6ft long and 6ft high, compared to 7.2 x 7.2ft on the ISS 

 ‘The International Habitation module will have habitable space of about 8 cubic meters [280 cubic feet] and you will have to share it with three others,’ space architect René Waclavicek said

Lunar Gateway forms a core part of the Artemis missions, the first of which was successfully completed at the end of last year.

It is hoped that Artemis III, scheduled to launch in 2025, will see NASA put the first woman and next man on the moon.

The US space agency wants to use its massive Space Launch System rocket to blast four astronauts into orbit onboard an Orion crew capsule, which will then dock with Gateway if it is ready.

A separate craft based on Elon Musk’s Starship design, docked with the Gateway, will be there waiting to receive two crew members for the final leg of the journey to the surface of the moon.

The astronauts would spend a week on the moon before boarding Starship to return to lunar orbit, then take Orion back to Earth. 

Musk’s company SpaceX is also due to launch the foundational elements of the Gateway to lunar orbit, including the Power and Propulsion Element (PPE) and the HALO.

Plans: When Gateway is finished it will be about one sixth of the size of the ISS and feature two habitation modules that will force crew members to exist in very close proximity to each other

Although Gateway won’t have a massive viewing window like on the ISS, it will have smaller ones in the fuelling module ESPIRIT.

The reason it can’t have a big one is again because of the technical issues associated with it — ‘glass is very heavy so a window is the first thing that gets canceled’, Waclawicek said.

The team has now begun building a real-size mockup for testing human interaction with the habitat environment.

I-Hab’s journey to the moon is not expected before 2027, although the American HALO module could be launched as early as 2024.

EXPLAINED: THE $100 BILLION INTERNATIONAL SPACE STATION SITS 250 MILES ABOVE THE EARTH

The International Space Station (ISS) is a $100 billion (£80 billion) science and engineering laboratory that orbits 250 miles (400 km) above Earth.

It has been permanently staffed by rotating crews of astronauts and cosmonauts since November 2000. 

Crews have come mainly from the US and Russia, but the Japanese space agency JAXA and European space agency ESA have also sent astronauts. 

The International Space Station has been continuously occupied for more than 20 years and has been expended with multiple new modules added and upgrades to systems 

Research conducted aboard the ISS often requires one or more of the unusual conditions present in low Earth orbit, such as low-gravity or oxygen.

ISS studies have investigated human research, space medicine, life sciences, physical sciences, astronomy and meteorology.

The US space agency, NASA, spends about $3 billion (£2.4 billion) a year on the space station program, with the remaining funding coming from international partners, including Europe, Russia and Japan.

So far 244 individuals from 19 countries have visited the station, and among them eight private citizens who spent up to $50 million for their visit.

There is an ongoing debate about the future of the station beyond 2025, when it is thought some of the original structure will reach ‘end of life’.

Russia, a major partner in the station, plans to launch its own orbital platform around then, with Axiom Space, a private firm, planning to send its own modules for purely commercial use to the station at the same time. 

NASA, ESA, JAXA and the Canadian Space Agency (CSA) are working together to build a space station in orbit around the moon, and Russia and China are working on a similar project, that would also include a base on the surface.

NASA James Webb Space Telescope’s most spectacular images

Since launching on Christmas Day 2021, NASA’s $10 billion (£7.4 billion) James Webb Space Telescope (JWST) has beamed back astonishing images of the cosmos with unprecedented detail. 

Webb was launched with the aim of looking back in time to the dawn of the universe so it can capture what happened a couple of hundred million years after the Big Bang. 

It will spend more than a decade at an area of balanced gravity between the sun and Earth called L2 exploring the universe in the infrared spectrum, allowing it to gaze through clouds of gas and dust where stars are being born. 

Here are some of the best images so far, including a snap of the ‘Pillars of Creation’, Neptune’s rings, a ‘cartwheel galaxy’ and a ‘cosmic dance’ between five galaxies.

NGC 346 STAR CLUSTER  

JWST released a new image this week, providing new insights into how stars formed in the early universe more than 10 billion years ago.

The image shows a young cluster of stars NGC 346, which is more than 200,000 light-years from Earth.

Located in the Small Magellanic Cloud (SMC) – a dwarf galaxy near the Milky Way – NGC 346 is interesting to astronomers because it resembles the conditions of the early Universe when star formation was at its peak.

Astronomers believe studying this region could help shed light on how the first stars formed during the ‘cosmic noon’, which is only two or three billion years after the Big Bang.

NASA ‘s James Webb Space Telescope (JWST) released a new image this wek, providing new insights into how stars formed in the early universe more than 10 billion years ago. 

How does the James Webb Space Telescope see back in time? 

The further away an object is, the further back in time we are looking. 

This is because of the time it takes light to travel from the object to us.

With James Webb’s larger mirror, it will be able to see almost the whole way back to the beginning of the Universe, around 13.7 billion years ago.

With its ability to view the Universe in longer wavelength infrared light, James Webb will be capable of seeing some of the most distant galaxies in our Universe, certainly with more ease than than the visible/ultraviolet light view of Hubble.

This is because light from distant objects is stretched out by the expansion of our Universe – an effect known as redshift – pushing the light out of the visible range and into infrared.

SOUTHERN RING NEBULA 

In July, NASA released the first four images captured by JWST, including the Southern Ring nebula, a planetary nebula – an expanding, glowing shell of ionized gas ejected from red giant stars late in their lives. 

According to NASA, the Southern Ring nebula is nearly half a light-year in diameter and is located about 2,000 light years away from Earth.

The dimmer star at the centre of the image has been sending out rings of gas and dust for thousands of years in all directions, giving it the appearance of a bright glint on a precious sapphire. 

The dying star is cloaked in dust as it undertakes its ‘final performance’, as NASA put it – something that our sun will go through in billions of years. 

Southern Ring Nebula is shown almost face-on, but if it were to be rotated to view it edge-on, its three-dimensional shape would more clearly look like two bowls placed together at the bottom, opening away from one another with a large hole at the centre. 

There are two images of the Southern Ring nebula, captured by two different instruments on James Webb –Near-Infrared Camera (NIRCam) and Mid-InfraRed Instrument (MIRI), which sees light in the mid-infrared region of the electromagnetic spectrum. 

The stars – and their layers of light – are prominent in the image from NIRCam, while the image from MIRI shows for the first time the nebula’s second star. 

NASA said the brighter star influences the nebula’s appearance, and as the pair orbit one another, they ‘stir the pot’ of gas and dust, causing asymmetrical patterns. 

These two images also reveal a cache of distant galaxies – not stars – in the background, appearing as a variety of multi-colored points of light seen here are galaxies.

Eagle-eyed views will also notice a blueish line to the left, which NASA astronomer Karl Gordon had said he originally thought it was part of the nebula. 

However, he later realised it was a galaxy captured edge-on. Such a perspective could reveal more about how stars are distributed throughout a galaxy.

Two cameras aboard Webb captured the latest image of this planetary nebula, cataloged as NGC 3132, and known informally as the Southern Ring Nebula. It is approximately 2,500 light-years away. One image was taken in the near-infrared (NIRCam, left) and another in the mid-infrared (MIRI, right)

Instruments on the James Webb telescope 

NIRCam (Near InfraRed Camera) an infrared imager from the edge of the visible through the near infrared  

NIRSpec (Near InfraRed Spectrograph) will also perform spectroscopy over the same wavelength range. 

MIRI (Mid-InfraRed Instrument) will measure the mid-to-long-infrared wavelength range from 5 to 27 micrometers.

FGS/NIRISS (Fine Guidance Sensor and Near Infrared Imager and Slitless Spectrograph), is used to stabilise the line-of-sight of the observatory during science observations.

SMACS 0723 

Another image from the first batch released in July shows the galaxy cluster SMACS 0723 as it appeared 4.6 billion years ago.

Galaxy clusters are the largest objects in the universe that are held together by their own gravity.

They contain hundreds or thousands of galaxies, lots of hot plasma, and a large amount of dark matter – invisible mass that only interacts with regular matter through gravity and doesn’t emit, absorb or reflect light. 

This image of SMACS 0723 covers a patch of sky approximately the size of a grain of sand held at arm’s length by someone on the ground – and reveals thousands of galaxies in a tiny sliver of vast universe. 

According to NASA, SMACS 0723 has a gravitational pull so powerful that it warps both space-time and the path that light subsequently travels through it. 

Because of this, bright white galaxies are warping and stretching the light from the more distant galaxies, making them seem elongated, almost banana-shaped. 

The combined mass of SMACS 0723 operates as a gravitational lens and, according to NASA, ‘magnify and distort the light of objects behind them, permitting a deep field view into both the extremely distant and intrinsically faint galaxy populations’.

Galaxy clusters, like SMACS 0723, are the largest objects in the universe that are held together by their own gravity. Here is the original image, released by NASA

NASA said Webb’s NIRCam, which captures light from the edge of the visible through the near infrared range of the electromagnetic spectrum, has brought distant galaxies into sharp focus in the new image.

Tiny, faint structures that have never been seen before, including star clusters – groups of hundreds to millions of stars that share a common origin, all gravitationally bound for as long as several billions of years. 

STEPHAN’S QUINTET

Next up is Stephan’s Quintet, a group of five galaxies in the constellation Pegasus, first discovered by French astronomer Édouard Stephan in 1877. 

It’s fair to say Mr Stephan would be blown away by the new James Webb image of his discovery, which captures the five galaxies in ‘exquisite detail’, NASA says. 

Four of the five galaxies within the quintet are locked in a ‘cosmic dance’ of repeated close encounters. 

‘Dust lanes crossing between galaxies and long filaments of stars and gas extending far beyond the central regions all suggest galaxies twisted by violent encounters,’ the European Space Agency says. 

‘The galaxies float through space, distorted shapes moulded by tidal interactions, weaving together in the intricate figures of an immense cosmic dance, choreographed by gravity.’

Two of the five galaxies, NGC 7318 a and b, forms a pair, and almost appear as one in the new image. 

The brightest member of the five is spiral galaxy NGC 7320, to the left of the picture, which is closer than the others.

Stephan’s Quintet is a group of five galaxies in the constellation Pegasus, first discovered by French astronomer Édouard Stephan in 1877 

NGC 7320 has extensive ‘H II region’ – regions of ionized hydrogen atoms, depicted as red blobs, where star formation is occurring. 

NASA said the image is an enormous mosaic, covering about one-fifth of the moon’s diameter. It contains more than 150 million pixels and is constructed from almost 1,000 separate image files. 

Stephan’s Quintet is famous for appearing as angelic figures at the beginning of the much-loved 1946 Christmas film ‘It’s a Wonderful Life’, starring James Stewart and Donna Reed. 

CARINA NEBULA

The Carina Nebula is one of the brightest and biggest nebulae in space, located about 7,600 light-years away in the southern constellation called Carina.

Nebulae are stellar nurseries where stars are birthed and this particular one is home to many gigantic stars, including some larger than the sun.

At the bottom of the image is the western section of NGC 3324, and what NASA calls the ‘Cosmic Cliffs’ – an orangey-brown landscape of ‘craggy mountains’ and ‘valleys’ speckled with glittering baby stars. NASA experts don’t even know what some of the structures are in this image, because they are so unprecedented 

TIMELINE OF THE JWST JOURNEY TO L2 

The Jame Webb Space Telescope will spend the rest of its life at the second Lagrangian point between the Earth and the Sun.

This is a point where the gravitational forces of the two bodies are balanced.

It is just under a million miles from the Earth’s surface, and on the way there JWST will perform a number of tasks.

  • 3-9 days: Deployed the delicate sunshield that will keep it cool 
  • 10-11 days: Deployed secondary mirror 
  • 12-14 days: Deployed primary mirror
  • 15-26 days: Unfold and check the mirror segments 
  • 29 days: Insertion into the L2 point 
  • 6 months: First images after months of calibration

The stunning shot shows the edge of a nearby, young, star-forming region called NGC 3324 in the Carina Nebula. 

At the bottom of the image is the western section of NGC 3324, and what NASA calls the ‘Cosmic Cliffs’ – an orangey-brown landscape of ‘craggy mountains’ and ‘valleys’ speckled with glittering baby stars. 

The blistering, ultraviolet radiation from the young stars is sculpting the nebula’s wall by slowly eroding it away. The tallest ‘peaks’ in this image are about seven light-years high. 

NASA says: ‘Dramatic pillars tower above the glowing wall of gas, resisting this radiation. The ‘steam’ that appears to rise from the celestial ‘mountains’ is actually hot, ionized gas and hot dust streaming away from the nebula due to the relentless radiation.’ 

Captured in infrared light by NASA’s new James Webb Space Telescope, this image reveals for the first time previously invisible areas of star birth.

‘Today, for the first time, we’re seeing brand new stars that were completely hidden from our view,’ said Amber Straughn, deputy project scientist for the James Webb Space Telescope.

‘We see examples of bubbles and cavities and jets that are being blown out by these newborn stars. We even see some galaxies sort of lurking in the background up here.

‘We see examples of structures that honesty we don’t even know what they are.’ 

PILLARS OF CREATION 

Webb also revealed a fresh look at the spectacular ‘Pillars of Creation’, the trunks of interstellar gas and dust in the Eagle Nebula. 

These were previously snapped in 1995 by Hubble, JWST’s predecessor, but the new image provides an incredible level of detail never before seen. 

It shows finger-like tendrils of gas and dust, glowing edges of dust where young stars are beginning to form, and newly-formed stars in orange outside the pillars. 

Beautiful: Almost 30 years ago the Pillars of Creation stunned the astronomy world when they were captured by NASA’s famed Hubble Space Telescope. Now a new generation can enjoy a fresh view of the haunting scene after the US space agency’s $10 billion (£7.4 billion) super space telescope James Webb imaged the same finger-like tendrils of gas and dust (pictured)

The first image of the Pillars of Creation was taken by Hubble in 1995. It provided the first evidence that stars could be birthed within the pillars

The latest image was taken in mid-infrared light, which blocks out the brightness of stars so it only captures the flowing gas and dust. This provided a new way of experiencing and understanding the stunning formation. 

TARANTULA NEBULA 

Another JWST image released by NASA in September shows thousands of young stars in a spider-shaped stellar nursery known as the Tarantula Nebula. 

The cosmic nursery, officially called 30 Doradus, is located 161,000 light-years away in the Large Megallanic Cloud galaxy, which happens to be the biggest and brightest star-forming region in the Local Group — the galaxies closest to our Milky Way. 

NASA said the Tarantula Nebula is the largest and brightest star-forming region near our galaxy, and home to the hottest, most massive stars known.

In this mosaic image stretching 340 light-years across, Webb’s Near-Infrared Camera (NIRCam) displays the Tarantula Nebula star-forming region in a new light, including tens of thousands of never-before-seen young stars that were previously shrouded in cosmic dust 

Viewed with Webb’s Near-Infrared Camera (NIRCam), the region resembles a burrowing tarantula’s home, lined with its silk. 

The nebula’s cavity centered in the NIRCam image appears to be hollowed out by blistering radiation from a cluster of massive young stars, which sparkle pale blue in the image. 

EXOPLANET HIP 65426 

JWST also captured its first image of an exoplanet — a planet outside our solar system.

Exoplanet HIP 65426 is located just 385 light years from Earth, and is just 15 to 20 million years old, which is much younger compared with our 4.5-billion-year-old Earth.

The telescope used NIRCam and MIRI that can block out surrounding starlight to snap epic images of the exoplanet.

NASA’s James Webb Telescope captured detailed images of its first exoplanet that sits outside of our solar system. The telescope used its powerful technologies to ‘see’ the exoplanets longer wavelengths that are missed by Earth-based telescopes

Exoplanets have ‘exotic’ rocks that can’t be found in our solar system 

Rocky planets outside our solar system (exoplanets) are composed of ‘exotic’ rock types that don’t even exist in our planetary system, a 2021 study shows. 

Experts used telescope data to analyse white dwarfs (former stars that were once gave life just like our sun) to uncover secrets of their former surrounding planets. 

They found some exoplanets have rock types that don’t exist or can’t be found on planets in our solar system.

These rock types are so ‘strange’ that the authors have had to create new names for them – including ‘quartz pyroxenites’ and ‘periclase dunites’.

The alien world was first discovered in 2017 by the European Southern Observatory’s Very Large Telescope, in Chile, but the long wavelengths were blocked by Earth’s atmosphere.

However, since Webb is soaring through space, it was able to take direct shots of the planet that astronomers can process to remove the starlight and uncover the planet.

NASA said it is a gas giant that is without a rocky surface and therefore could not host life.

NORTH ECLIPTIC POLE GALAXIES 

Another image released earlier this month shows an early universe with faint, distant lights beaming from newly formed galaxies in an area known as the North Ecliptic Pole.

The thousands of never-before-seen galaxies formed 13.5 billion years ago — around 200 million years after the Big Bang. 

Cosmic objects seen in the image are one billion times fainter than what can be seen by the unaided eye, but the telescope’s Near-Infrared Camera (NIRCam) captured the spectra of light coming from objects in the image.

The North Ecliptic Pole is located in the constellation Draco, one of the largest in the sky, which sits in the northern celestial hemisphere.

It is one of the ancient Greek constellations and was first cataloged by the Greek astronomer Ptolemy in the 2nd century.

This image from NASA’s telescope captures thousands of never-before-seen galaxies that formed 13.5 billion years ago – 200 million years after the big bang

CARTWHEEL GALAXY 

JWST has snapped other images of spiral galaxies, with one that reveals the chaos of the Cartwheel Galaxy that is 489.2 million light-years from Earth. 

Much like a wagon wheel, its appearance results from an extreme event — a high-speed collision between a large spiral galaxy and a smaller galaxy not visible in this image.

Other telescopes, including the Hubble Space Telescope, have previously examined the Cartwheel.

But the dramatic galaxy has been shrouded in mystery — perhaps literally, given the amount of dust that obscures the view.

The Cartwheel Galaxy sports two rings — a bright inner ring and a surrounding, colorful ring. These rings expand outwards from the centre of the collision, like ripples in a pond after a stone is tossed into it.     

Fireworks: The James Webb Space Telescope is once again wowing with its view of the universe. It has peered into the chaos of the Cartwheel Galaxy (pictured), revealing new details about star formation and the galaxy’s central black hole

NEPTUNE’S RINGS  

JWST captured the clearest view of Neptune’s rings in more than 30 years, since the Voyager 2 probe flew past the distant planet in 1989. 

In addition to several bright, narrow rings, the Webb image clearly shows the planet’s fainter dust bands. 

Beyond the planet itself are seven of the giant’s 14 moons, the most significant of which is Triton. This appears almost star-like because Neptune is darkened in Webb’s view by methane absorption at infrared wavelengths. 

Triton, however, reflects an average of 70 per cent of the sunlight that strikes its icy surface so it shows up extremely bright. 

Mesmerising: The James Webb Space Telescope has captured the clearest view of Neptune’s rings in more than 30 years

NASA has anticipated that JWST, which is now orbiting the sun at a million miles (1.6 million kilometres) from Earth, should last 20 years.

‘The instruments are more efficient, the optics are sharper and more stable. We have more fuel and we use less fuel,’ said Massimo Stiavelli, head of the Webb mission office at the Space Telescope Science Institute, in Baltimore. 

The orbiting infrared observatory is designed to be about 100 times more powerful than its predecessor, the Hubble Space Telescope.

NASA likes to think of James Webb as a successor to Hubble rather than a replacement, as the two will work in tandem for a while. 

The JWST project, which started in 1996, is an international collaboration led by NASA in partnership with the European and Canadian space agencies.  

James Webb Space Telescope began development in 1996 and was originally envisaged to launch in 2007, but a major redesign in 2005 put this back. 

Construction was finally completed in 2016 and an extensive period of testing work began, but this was delayed by the Covid-19 pandemic. 

Launch had been scheduled for March 2021 before being delayed to October, and then again until December.

The James Webb Telescope: NASA’s $10 billion telescope is designed to detect light from the earliest stars and galaxies

The James Webb telescope has been described as a ‘time machine’ that could help unravel the secrets of our universe.

The telescope will be used to look back to the first galaxies born in the early universe more than 13.5 billion years ago, and observe the sources of stars, exoplanets, and even the moons and planets of our solar system.

The vast telescope, which has already cost more than $7 billion (£5 billion), is considered a successor to the orbiting Hubble Space Telescope

The James Webb Telescope and most of its instruments have an operating temperature of roughly 40 Kelvin – about minus 387 Fahrenheit (minus 233 Celsius).

It is the world’s biggest and most powerful orbital space telescope, capable of peering back 100-200 million years after the Big Bang.

The orbiting infrared observatory is designed to be about 100 times more powerful than its predecessor, the Hubble Space Telescope.

First implant to treat depression is REVEALED: New brain chip set to rival Elon Musk’s Nueralink

While Elon Musk’s Neuralink expects to begin human trials in six months, a neurotech company unveiled a device that treats depression and is now in the skull of the first patient.

Inner Cosmos’s ‘digital pill’ includes two parts: An electrode that sits under the skin of the scalp and the ‘prescription pod’ that snaps onto the users’ hair to power the device.

The implant sends tiny electrical pulses to the brain region affected by depression – the left dorsolateral prefrontal cortex – once daily for 15 minutes.

And the external device does not need to be on the head when treatment is not being administered.

The trial patient from St Louise, Missouri, is scheduled to test Inner Cosmos innovation for one year, and the company has another human trial set to start next month.

Inner Cosmos has unveiled the first brain implant to treat depression. The digital pill is the smallest and least invasive technology to date – the implant is about the size of a penny

Implants to treat all alignments of the brain are making waves in the industry, as several companies are racing to get theirs to market first.

Musk’s Neuralink recently conducted a product demonstration that showed its chip in a monkey’s brain, allowing it to control a keyboard on a screen to type out complete sentences.

Synchron began human trials of its brain implant in July, which lets the wearer control a computer using thought alone.

The firm’s Stentrode brain implant, about the size of a paperclip, will be implanted in six New York and Pittsburgh patients with severe paralysis. 

Stentrode will let patients control digital devices just by thinking and give them the ability to perform daily tasks, including texting, emailing and shopping online. 

Research facilities are also developing brain chips.

Southmead Hospital in Bristol is believed to be the first in the world to implant a device to reverse symptoms of Parkinson’s.

However, Inner cosmos digital pill is the smallest and least invasive technology to date – the implant is about the size of a penny.

And the company likens the external pod to charging an Apple Watch. 

The surgery for the implant takes 30 minutes in an outpatient facility. 

Inner Cosmos was founded by entrepreneur Meron Gribetz, who was diagnosed with attention deficit disorder as a child.

‘Our mission is to create a world that restores humanity’s cognitive power by rebalancing the human mind,’ said Gribetz.

‘The world is in a state of severe disorder, leading to a disordered cognition 

‘The effects are being felt by millions, leading to surging levels of depression. 

‘We believe our approach can allay the lives of those suffering from depression, and eventually scale to other cognitive disorders.’

The goal of Inner Cosmos is to move away from prescription drugs and toward a more ‘effective treatment.’ 

‘Depression, attention and anxiety, which we treat. Just to underscore this point, there’s 140 million Americans every year that use attention or depression drugs, that’s more users than have iPhones,’  Gribetz said in a 2022 presentation.

Inner Cosmos’s ‘digital pill’ includes two parts: An electrode that sits under the skin of the scalp and the ‘prescription pod’ that snaps onto the users’ hair to power the device

The implant sends pulses to the brain region affected by depression – the left dorsolateral prefrontal cortex – once a day for 15 minutes. And the external device does not need to be on the head when treatment is not being administered

Inner Cosmos digital pill is powered by a smartphone app, which also displays mood and depression graphs that can be shared with a physician. 

Gribetz said this is the first time doctors will have access to this type of data, ‘saving the healthcare industry billions for misdiagnosis of severe suicidal depression,’ he said.

‘[The implant] is 10 times smaller than anything else that you’ve heard of globally, on the brain chips BCI [brain computer interface] market, and we’re really excited,’ said Gribetz. ‘It took us six years to build this thing.’

Two supermassive black holes found dining side-by-side with just 750 light-years between them 

Black hole BANQUET! Scientists discover two supermassive black holes dining side-by-side with just 750 light-years between them

  • Two supermassive black holes have been spotted ‘dining’ side-by-side
  • The pair are growing simultaneously just 750 light years apart 
  • Astronomers believe they will eventually combine into a gargantuan black hole 

One black hole is mind-boggling enough – a region in space where gravity is so immense that nothing, even light, can escape from it.

Now astronomers have discovered something even more remarkable, as two black holes have been spotted ‘dining’ side-by-side.

The pair are growing simultaneously just 750 light years apart – the closest scientists have ever observed – and will eventually combine into a gargantuan black hole.

They were discovered by researchers using the ALMA telescope, the most powerful telescope for observing molecular gas and dust, which is located in the Atacama desert.

One black hole is mind-boggling enough – a region in space where gravity is so immense that nothing, even light, can escape from it. Now astronomers have discovered something even more remarkable, as two black holes have been spotted ‘dining’ side-by-side

As the team were looking at two galaxies merging in the constellation Cancer, 500 million light years from Earth, they saw something they ‘didn’t expect’.

They spotted two glowing black holes, gluttonously devouring the dust, gas and other material being displaced by the merger, as if at a banquet.

While the black holes are close together in cosmological terms, they won’t merge for a few hundred million years.

Eventually, they will begin circling each other, with the orbit tightening as gas and stars pass between them.

The pair are growing simultaneously just 750 light years apart – the closest scientists have ever observed – and will eventually combine into a gargantuan black hole

Ultimately the black holes will start producing gravitational waves far stronger than any that have previously been detected, the researchers said, before crashing into each other to form one jumbo-sized black hole.

The findings also suggest that binary black holes and the merging galaxies that create them may actually be surprisingly common in the Universe.

Experts said the use of ALMA, which stands for Atacama Large Millimetre/submillimetre Array, was a ‘game changer’ and that finding two black holes so close together could pave the way for additional studies of the phenomenon.

Michael Koss, lead author of the research, is from the National Radio Astronomy Observatory.

He said: ‘ALMA is unique in that it can see through large columns of gas and dust and achieve very high spatial resolution to see things very close together.

‘Our study has identified one of the closest pairs of black holes in a galaxy merger, and because we know that galaxy mergers are much more common in the distant Universe, these black hole binaries too may be much more common than previously thought.’

The results of the new research were published in The Astrophysical Journal Letters and presented at the meeting of the American Astronomical Society in Seattle, Washington.

‘Black hole police’ discover the first dormant black hole outside the Milky Way 

BLACK HOLES HAVE A GRAVITATIONAL PULL SO STRONG NOT EVEN LIGHT CAN ESCAPE

Black holes are so dense and their gravitational pull is so strong that no form of radiation can escape them – not even light.

They act as intense sources of gravity which hoover up dust and gas around them. Their intense gravitational pull is thought to be what stars in galaxies orbit around.

How they are formed is still poorly understood. Astronomers believe they may form when a large cloud of gas up to 100,000 times bigger than the sun, collapses into a black hole.

Many of these black hole seeds then merge to form much larger supermassive black holes, which are found at the centre of every known massive galaxy.

Alternatively, a supermassive black hole seed could come from a giant star, about 100 times the sun’s mass, that ultimately forms into a black hole after it runs out of fuel and collapses.

When these giant stars die, they also go ‘supernova’, a huge explosion that expels the matter from the outer layers of the star into deep space.
