Stunning New NASA Pic Reveals Lava Glowing Red Hot on Jupiter’s Moon : ScienceAlert
NASA’s Juno spacecraft captured an infrared image of Jupiter’s moon Io from 50,000 miles (80,000 kilometers) away.
In the image, taken on July 5 and released on Wednesday, you can see the shapes of lava flows and lava lakes as bright red spots.
“You can see volcanic hotspots. We’ve been able to monitor over the course of the primary mission – over 30 orbits – how this changes and evolves,” Scott Bolton, principal investigator for NASA’s Juno spacecraft, said in a press event at the American Geophysical Union’s Fall Meeting on Wednesday.
Io is home to hundreds of volcanoes, NASA has found. Surprisingly, scientists found more volcanic spots in the polar region than in the planet’s equatorial region, Bolton said.
The space probe Juno has been orbiting Jupiter since 2016. After studying the gas giant, Juno flew by Jupiter’s moon Ganymede in 2021 and by Europa earlier this year.
The spacecraft is scheduled to explore Io, which NASA says is the “the most volcanic place in the solar system,” again on December 15. It’s the first of nine flybys Juno has planned over the next year and a half.
Scientists hope to gather more data on the moon’s volcanoes and its magnetism – which play a “tug of war” to form Jupiter’s auroras – as they fly by.
“As we watch the volcanoes change and get active and less active, they’re driving Jupiter’s gigantic monster magnetosphere,” Bolton said on Wednesday.
Auroras are colorful displays of light that are not unique to Earth. Jupiter has the brightest auroras in the solar system, according to NASA.
On both Earth and Jupiter, auroras occur when charged particles, such as protons or electrons, interact with the magnetic field – known as the magnetosphere – that surrounds a planet. Jupiter’s magnetic field is about 20,000 times stronger than Earth’s.
The data and insights Juno gleans could help inform future missions to study Jupiter’s moons, like NASA’s Clipper mission, which will investigate whether Europa could support life.

Viewers flock to watch glowing lava ooze from Hawaii volcano
KAILUA-KONA, Hawaii (AP) — The world’s largest volcano oozed rivers of glowing lava Wednesday, drawing thousands of awestruck viewers who jammed a Hawaii highway that could soon be covered by the flow.
Mauna Loa awoke from its 38-year slumber Sunday, causing volcanic ash and debris to drift down from the sky. A main highway linking towns on the east and west coasts of the Big Island became an impromptu viewing point, with thousands of cars jamming the highway near Volcanoes National Park.
Anne Andersen left her overnight shift as a nurse to see the spectacle Wednesday, afraid that the road would soon be closed.
“It’s Mother Nature showing us her face,” she said, as the volcano belched gas on the horizon. “It’s pretty exciting.”
Gordon Brown, a visitor from Loomis, California, could see the bright orange lava from the bedroom of his rental house. So he headed out for a close-up view with his wife.
“We just wanted … to come see this as close as we could get. And it is so bright, it just blows my mind,” Brown said.
The lava was tumbling slowly down the slope and was about 6 miles (10 kilometers) from the highway known as Saddle Road. It was not clear when, or if, it would cover the road, which runs through old lava flows.
The road bisects the island and connects the cities of Hilo and Kailua-Kona. People traveling between them would need to take a longer coastal road if Saddle Road becomes impassable, adding several hours of drive time.
Ken Hon, scientist in charge at the Hawaiian Volcano Observatory, said at current flow rate, the soonest the lava would get to the road is two days, but it will likely take longer.
“As the lava flow spreads out, it will probably interfere with its own progress,” Hon said.
Kathryn Tarananda, 66, of Waimea set two alarms to make sure she didn’t oversleep and miss her chance with a friend to see sunrise against the backdrop of eruptions at Mauna Loa.
“It’s a thrill,” she said. “We’re out in the middle of raw nature. It’s awe inspiring that we live in this place. … I feel really, really fortunate to be an islander.”
Mauna Loa last erupted in 1984. The current eruption is its 34th since written record keeping began in 1843. Its smaller neighbor, Kilauea, has been erupting since September 2021, so visitors to the national park were treated to the rare sight of two simultaneous eruptive events: the glow from Kilauea’s lava lake and lava from a Mauna Loa fissure.
Abel Brown, a visitor from Las Vegas, was impressed by the natural forces on display. He planned to take a close-up helicopter tour later in the day — but not too close.
“There’s a lot of fear and trepidation if you get really close to it,” Brown said. “The closer you get, the more powerful it is and the more scary it is.”
Officials were initially concerned that lava flowing down Mauna Loa would head toward the community of South Kona, but scientists later assured the public the eruption had migrated to a rift zone on the volcano’s northeast flank and wasn’t threatening communities.
The smell of volcanic gases and sulfur was thick along Saddle Road, where people watched the wide stream of lava creep closer. Clouds cleared to reveal a large plume of gas and ash rising from a vent on the mountain.
Gov. David Ige issued an emergency proclamation to allow responders to arrive quickly or limit access as needed.
Lava crossed the Mauna Loa Observatory access road Monday night and cut off power to the facility, Hon said. It’s the world’s premier station that measures heat-trapping carbon dioxide in the atmosphere. The federal government is looking for a temporary alternate site on the Hawaiian island and is contemplating flying a generator to the observatory to get its power back so it can take measurements again.
Meanwhile, scientists are trying to measure the gas emitted from the eruption.

Jupiter is glowing in new pictures from NASA’s James Webb Space Telescope
An early look at the view of Jupiter captured by NASA’s James Webb Space Telescope, or JWST, hinted at how precise and detailed our new view of the planet would be. But this week, NASA released another set of photos showing the cloud cover, rings, and moons of Jupiter in remarkable detail — and it was even better than scientists were hoping for.
“We hadn’t really expected it to be this good, to be honest,” said planetary astronomer Imke de Pater, professor emerita of the University of California, Berkeley, in a press release. “It’s really remarkable that we can see details on Jupiter together with its rings, tiny satellites, and even galaxies in one image.”
The telescope uses a camera with three filters that translate infrared light into colors that the human eye can see. The filter mapped to red colors shows Jupiter’s auroras, which shine off the planet’s poles. Light reflected from deep clouds appears in blues. And the planet’s weird atmospheric hazes show up in a filter of green and yellow. The planet’s famous Great Red Spot — an enormous storm bigger than Earth — is so bright that it appears white. The white streaks and spots are likely from reflected sunlight bouncing off particularly high-altitude clouds, NASA says.
Zoomed-out images show the planet’s faint rings and two moons, which scientists are analyzing to learn more about the planet.
Taking the information from the JWST and translating it into processed, beautiful images was particularly difficult with Jupiter. The planet is much closer than more distant celestial objects and rotates comparatively quickly, said Judy Schmidt, a citizen scientist and the image processor for these new looks at the planet, in NASA’s press release. Schmidt and others had to combine several images to get these pictures of the gas giant.
With these new images, Jupiter joins Stephan’s Quintet (a cluster of five galaxies), exoplanet WASP-96 b, the Southern Ring Nebula, and a handful of other cosmic characters who have already gotten their close-up with the JWST. And they’re just the start — there’s so much more to explore, and more images are coming soon.
Glowing snailfish riddled with antifreeze protein discovered off Greenland coast
Scientists drilling deep into an iceberg off Greenland have discovered a fish with glowing green antifreeze coursing through its veins.
The juvenile variegated snailfish (Liparis gibbus) contained the “highest expression levels” of antifreeze proteins ever reported, a new study found.
Similar to how antifreeze helps to regulate the temperature of a car’s engine in extreme conditions, certain species have evolved to have similar protection, especially those living in frigid habitats such as the polar waters off Greenland.
“Antifreeze proteins stick to the surface of smaller ice crystals and slow or prevent them from growing into larger, and more dangerous, crystals,” study co-author David Gruber, a research associate at the American Museum of Natural History (AMNH) and a distinguished biology professor at City University of New York’s Baruch College, told Live Science in an email. “Fish from both the North and South Poles independently evolved these proteins.”

Antifreeze proteins were first discovered in some Antarctic fish nearly 50 years ago, according to the National Science Foundation (opens in new tab).
Unlike certain cold-blooded species of reptiles and insects, fish are unable to survive when their bodily fluids freeze, which can cause grains of ice to form inside their cells and essentially turns them into fish Popsicles.
“The fact that these different antifreeze proteins have evolved independently in a number of different — and not closely related — fish lineages show[s] how critical they are to the survival of these organisms in these extreme habitats,” John Sparks, a curator in the AMNH’s Department of Ichthyology and co-author of the study, told Live Science in an email.
Snailfish produce antifreeze proteins “like any other protein and then excrete them into their bloodstream,” Gruber said. However, snailfish appear to be “making antifreeze proteins in the top 1% of all other fish genes.”
Scientists found the tiny tadpole-like creature in 2019 during an expedition as they explored the iceberg habitats off the coast of Greenland. During the trip — which was part of the Constantine S. Niarchos Expedition, a series of science-based expeditions led by the AMNH — the scientists were flummoxed when they discovered the biofluorescent snailfish glowing brilliant green and red in the icy habitat.
“The snailfish was one of the few species of fish living among the icebergs, in the crevices,” Gruber said. “It was surprising that such a tiny fish could live in such an extremely cold environment without freezing.”
It’s also rare for Arctic fishes to exhibit biofluorescence, which is the ability to convert blue light into green, red or yellow light, since there are prolonged periods of darkness, especially in the winter, at the poles. Normally this characteristic is found in fish swimming in warmer waters. This is the first reported case of an Arctic fish species exhibiting this adaptation, according to an AMNH post (opens in new tab).
The scientists further examined the biofluorescent properties of the snailfish and found “two different types of gene families encoding for antifreeze proteins,” according to a separate statement, an adaptation that essentially helps them avoid turning into frozen fish sticks.
This mind-boggling level of antifreeze production could help this species adapt to a subzero environment, according to the statement. It also raises a question about how snailfish will fare as ocean temperatures increase as a result of global warming.
“Due to rapidly warming waters in the Arctic, these cold-water-adapted species will also have to compete with warmer-water species that are now able to migrate north and survive at higher latitudes (and that won’t need to produce metabolically costly antifreeze proteins to survive in the warmer Arctic waters),” Sparks said. “In the future, [antifreeze] proteins may no longer provide an advantage.”
The findings were published Aug. 16 in the journal Evolutionary Bioinformatics (opens in new tab).

Satellite images + lucky boat trip give new info on glowing “milky seas”
Enlarge / The boat trip went through an area of milky sea south of the lights of an island.
On some moonless nights, enormous patches of the Northwest Indian Ocean and seas around Indonesia begin to glow. This event has been witnessed by hundreds of sailors, but only one research vessel has ever, by pure chance, come across this bioluminescent phenomenon, known as milky seas. Thanks to that vessel, samples showed that the source of the light was a bacteria called V. harveyi, which had colonized a microalgae called Phaocystis. But that was back in 1988, and researchers have yet to be in the right place and the right time to catch one of these events again.
Both the bacteria and algae are common to those waters, so it’s not clear what triggers these rare events. To help understand why milky seas form, researchers have gotten much better at spotting these swaths of bioluminescence from the skies. With the help of satellites, Stephen Miller, a professor of atmospheric science, has been collecting both images and eyewitness accounts of milky seas for nearly 20 years. Thanks to improvements in the imaging capabilities over the past decades, Miller published a compilation last year of probable milky seas in the time frame of 2012 to 2021, including one occurrence south of Java, Indonesia, in summer 2019.
But these satellite observations lacked surface confirmation—that is, until the crew of the yacht Ganesha reached out to Miller with their first-hand account of what they had experienced during their trip through the seas around Java that August, which was recently published in PNAS. Their eyewitness corroboration—along with the first photographs of a milky sea—show that these satellites are indeed a powerful tool for spotting these events.
Skies’ eyes
Although milky seas can be massive—greater than 100,000 square kilometers in the case of the 2019 sighting—the intensity of this bioluminescence is still relatively faint. By comparison, the better-known sea sparkle from marine plankton (dinoflagellates) is 10 times stronger—and even that can be hard to spot.
To catch milky seas by satellite, researchers like Miller and his collaborators had to wait for the installation of the Day/Light Band on the latest generation of National Oceanic and Atmospheric Administration (NOAA) environmental satellites. This low-light imager is sensitive enough to capture light 10,000 times weaker than reflected moonlight and about 1 billion times weaker than reflected sunlight. Day/Light Bands have been installed on two satellites: the Suomi National Polar-orbiting Partnership (launched in 2011) and the Joint Polar Satellite System series (launched in 2017).
Thanks to these satellites, Miller could search through 10 years of satellite data, in which he found 12 suspected milky seas between 2012 and 2021. This data showed that the events could last as long as weeks and that they often coincided with regional monsoons and algal blooms resulting from the upwelling of nutrient-rich waters.
“While milky seas are spectacular visual phenomenon with an interesting historical backstory tied to the maritime folklore, I think in modern times we are also very interested in understanding how and why this massive expression of our biosphere, associated with primary production (the very base of the marine food chain), occurs,” writes Miller in an email to Ars Technica. “I would like to translate this to a better awareness of atmosphere/ocean/biosphere coupling in Earth’s climate system, such that we can begin to understand how fundamental components of our planet’s ecosystem may respond in a changing climate.”
But all of Miller’s observations were coming from an altitude of over 800 km in the sky—until he heard from the Ganesha crew.
Michelle Williams is Glowing in the First Pics of Her Baby Bump – SheKnows
Michelle Williams stepped out at the 2022 Cannes Film Festival this week, pregnant and glowing. The actress, who is married to Hamilton director Thomas Kail, is expecting her third child. She walked the red carpet in Chanel ballet flats, Chanel Haute Couture and a diamond necklace.
Williams broke the news that she was pregnant earlier this month, during an interview with Variety. “It’s totally joyous,” Williams told the outlet. “As the years go on, you sort of wonder what they might hold for you or not hold for you. It’s exciting to discover that something you want again and again, is available one more time. That good fortune is not lost on me or my family.”

Williams and Kail welcomed their son Hart in 2020, right in the midst of the pandemic and during lockdown. The experience was a valuable one for the couple. “It was a reminder that life goes on,” Williams said. “The world we brought a baby into is not the world we thought we were bringing a baby into, but the baby is ignorant of that. He experiences the unmitigated joy of discovery and the happiness of a loving home.”
Williams also has a 16-year-old daughter named Matilda, who she shared with Heath Ledger. The couple were together from 2004 to 2007 and Ledger died of an accidental overdose a year later. Williams has been open about the ways that she keeps Ledger’s memory alive for Matilda, offering a thoughtful glimpse into what must be an incredibly difficult situation to navigate.
“You know, as hard as certain things have been for me, it’s harder thinking about how things will be for her,” Williams told GQ in 2012. “I have a lot of things that she doesn’t and some of what I have, I can give to her: The memories that I have, the objects that I have, the physical reminders that I have, the stories.”

Alien shopping-bag ocean weirdo has glowing Cheetos for guts
Resembling an alien shopping bag with guts made of glowing Cheetos, a bizarre creature took center stage in new footage captured by a remotely operated vehicle deep in the Pacific Ocean.
Gliding through the sea at a depth of some 7,221 feet (2,201 meters), the ocean weirdo — actually an unknown species of sea cucumber — had its innards on display in the new clip, taken in March by an ROV exploring part of the Pacific Remote Islands Marine National Monument southeast of Honolulu. The ROV was gliding over an unexplored seamount at the Kingman Reef and Palmyra Atoll when operators spotted the creature, said Megan Cook, the director of education and outreach at The Ocean Exploration Trust’s Nautilus Live.
“These are always so exciting and spectacular to see because — just, what an incredible animal,” Cook told Live Science.
Sea cucumbers, or holothurians, are a diverse group, with many species distributed across the Central Pacific, Cook said. The one spotted by the ROV linked to the research vessel E/V Nautilus crew belongs to a family called Elpidiidae, she said. These deep-sea cucumbers are scavengers that feed on marine snow, a shower of skin cells, poop and bits of dead animals that filters down to the ocean floor.

Many species in the Elpidiidae family have appendages that look like fins or sails that let them swim for short distances. This is a useful adaptation that allows the sea cucumbers to cover more ground and search for new grazing spots, Cook said.
To eat, the animal oozes across the seafloor, using its sticky tentacles — the leaf- or star-shaped red fringe around its mouth — to pick up a mix of sand and organic material, which it then brings to its mouth. The bright orange intestine — the glowing “Cheetos” — seen inside the transparent creature then digests the organic material, excreting the non-edible sand.
This turns out to be an important storage system for carbon. The ocean floor is the largest carbon sequestration system on Earth, with carbon-rich organic material getting scooped up by bottom-dwellers like sea cucumbers and remaining deep in the ocean for long periods of time.
“They are this great scavenger/recycler on the seafloor,” Cook said of the deep-sea sea cucumbers.
Some sea cucumber species can eject their digestive systems through their anuses when startled, a method that often lets them escape hungry predators. (The organs soon grow back.) However, it’s unknown if the species in the new video has that trick up its sleeve (or its anus), Cook said.
The EV Nautilus livestreams its ROV dives, and the current season runs through late October. The team will continue to explore the Central Pacific, including many unexplored spots in the Pacific Remote Islands Marine National Monument and its surroundings. Viewers can follow along on Twitter @EVNautilus, on Instagram at @NautilusLive, on TikTok @NautilusLive, on Facebook @NautilusLive or on YouTube at /EVNautilus.
“Our next ROV dives will be to Johnston Atoll, which is one of the most remote atolls in the whole planet,” Cook said.

Something’s Glowing at The Galactic Core, And We Could Be Closer to Solving The Mystery
Something deep in the heart of the Milky Way galaxy is glowing with gamma radiation, and nobody can figure out for sure what it might be.
Colliding dark matter has been proposed, ruled out, and then tentatively reconsidered.
Dense, rapidly rotating objects called pulsars were also considered as candidate sources of the high-energy rays, before being dismissed as too few in number to make the sums work.
A study by researchers from Australia, New Zealand and Japan could breathe new life into the pulsar explanation, revealing how it might be possible to squeeze some serious intense sunshine from a population of spinning stars without breaking any rules.
Gamma radiation isn’t your typical hue of sunlight. It requires some of the Universe’s most energetic processes to produce. We’re talking black holes colliding, matter being whipped towards light speed, antimatter combining with matter kinds of processes.
Of course, the center of the Milky Way has all of these things in spades. So when we gaze into the heavens and consider all of the crashing bits of matter, spiraling black holes, whizzing pulsars, and other astrophysical processes, we’d expect to see a healthy gamma glow.
But when researchers used NASA’s Fermi telescope to measure the intense shine within the heart of our galaxy about ten years ago, they found there was more of this high-energy light than they could account for: what’s known as the Galactic Centre Excess.
One exciting possibility involves unseen bits of matter bumping together in the night. These weakly interacting massive particles – a hypothetical category of dark matter commonly described as WIMPs – would cancel each other out as they smoosh together, leaving nothing but radiation to mark their presence.
It’s a fun explanation to consider, but is also light on evidence.
“The nature of dark matter is entirely unknown, so any potential clues garner a lot of excitement,” says astrophysicist Roland Crocker from the Australian National University.
“But our results point to another important source of gamma ray production.”
That source is the millisecond pulsar.
To make one, take a star much bigger than our own and let its fires die down. It will eventually collapse into a dense ball not much wider than a city, where its atoms pack together so tightly, many of its protons are slowly baked into neutrons.
This process generates super-strong magnetic fields that channel incoming particles into fast-flowing streams glowing with radiation.
Since the object is rotating, these streams swivel around from the star’s poles like the Universe’s biggest lighthouse beacons – so it appears to pulse with energy. Pulsing stars that spin hundreds of times a second are known as millisecond pulsars, and we know a lot about the conditions under which they’re likely to form.
“Scientists have previously detected gamma-ray emissions from individual millisecond pulsars in the neighborhood of the Solar System, so we know these objects emit gamma rays,” says Crocker.
To emit them, however, they’d need a generous amount of mass to feed on. Most pulsar systems in the center of the Milky Way are thought to be too puny to emit anything more energetic than X-rays, though.
That might not always be the case, however, especially if the dead stars they emerged from are of a particular variety of ultra-massive white dwarf.
According to Crocker, if enough of these heavyweights were to turn into pulsars and hold onto their binary partners, they would provide just the right amount of gamma radiation to match observations.
“Our model demonstrates that the integrated emission from a whole population of such stars, around 100,000 in number, would produce a signal entirely compatible with the Galactic Centre Excess,” says Crocker.
Being a purely theoretical model, it’s an idea that now needs a generous dose of empirical evidence. Unlike suggestions based on dark matter, however, we already know exactly what to look for.
