The Latest Milky Way Survey Shows Off an Incredible 3.32 Billion Celestial Objects : ScienceAlert

If you check in regularly to ScienceAlert, you’ll be familiar with quite a few stunning space images, but a newly published picture has to be one of the best yet: 2 years in the making, 10 terabytes worth of data, 21,400 individual exposures combined, and a final image showing a huge 3.32 billion celestial objects.

We have the Dark Energy Camera (DECam) to thank for this beautiful shot of space, part of the Víctor M. Blanco 4-meter Telescope at the Cerro Tololo Inter-American Observatory (CTIO), some 2,200 meters (7,218 feet) above sea level in Chile.

The image was issued as part of the Dark Energy Camera Plane Survey (DECaPS2), and it gives us more detail than ever before of this part of space – it accounts for around 6.5 percent of the entire night sky, focusing on the galactic plane of the Milky Way where the bulk of the galaxy’s mass is located.

A section of the new survey. (DECaPS2/DOE/FNAL/DECam/CTIO/NOIRLab/NSF/AURA; Image processing: M. Zamani & D. de Martin (NSF’s NOIRLab))

“One of the main reasons for the success of DECaPS2 is that we simply pointed at a region with an extraordinarily high density of stars and were careful about identifying sources that appear nearly on top of each other,” says astronomer Andrew Saydjari from Harvard University in Massachusetts.

“Doing so allowed us to produce the largest such catalog ever from a single camera, in terms of the number of objects observed.”

That high density brings with it a few issues: The vast swaths of space dust and the glow from brighter stars can block out the light from dimmer objects entirely. By measuring both optical and near-infrared wavelengths, DECam overcomes these problems.

The team also used a special data processing technique to better estimate how the background of each star should look, enabling more stars to be observed with greater clarity, and improving the overall accuracy of the picture.

When combined with other sky surveys – like the Pan-STARRS project – the latest telescope technology provides us an unprecedented look at the Universe outside of our planet, which of course, gives us clues as to how it came into being.

“When combined with images from Pan-STARRS 1, DECaPS2 completes a 360-degree panoramic view of the Milky Way’s disk and additionally reaches much fainter stars,” says astronomer Edward Schlafly from the Space Telescope Science Institute in Maryland.

“With this new survey, we can map the three-dimensional structure of the Milky Way’s stars and dust in unprecedented detail.”

The results are simply fantastic and very much worth the two-year wait. The data collected in the survey is freely available for other researchers and the wider public to make use of.

DECam was built initially to carry out a Dark Energy Survey and to better understand this mysterious force that is thought to be driving the Universe. It continues to produce amazingly detailed pictures of deep space, and there will be plenty more to come.

“This is quite a technical feat,” says astronomer Debra Fischer from the National Science Foundation (NSF) in the US, who wasn’t directly involved in the research. “Imagine a group photo of over three billion people, and every single individual is recognizable!”

“Astronomers will be poring over this detailed portrait of more than three billion stars in the Milky Way for decades to come. This is a fantastic example of what partnerships across federal agencies can achieve.”

The research has been published in the Astrophysical Journal Supplement Series.

NSF’s NOIRLab releases colossal astronomical data tapestry displaying the majesty of our Milky Way in unprecedented detail.

Astronomers have released a gargantuan survey of the galactic plane of the

The Milky Way Galaxy contains hundreds of billions of stars, glimmering star-forming regions, and towering dark clouds of dust and gas. Imaging and cataloging these objects for study is a herculean task, but a newly released astronomical dataset known as the second data release of the Dark Energy Camera Plane Survey (DECaPS2) reveals a staggering number of these objects in unprecedented detail. The DECaPS2 survey, which took two years to complete and produced more than 10 terabytes of data from 21,400 individual exposures, identified approximately 3.32 billion objects — arguably the largest such catalog compiled to date. Astronomers and the public can explore the dataset here.

This unprecedented collection was captured by the Dark Energy Camera (DECam) instrument on the Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory (CTIO), a Program of NSF’s NOIRLab. CTIO is a constellation of international astronomical telescopes perched atop Cerro Tololo in Chile at an altitude of 2200 meters (7200 feet). CTIO’s lofty vantage point gives astronomers an unrivaled view of the southern celestial hemisphere, which allowed DECam to capture the southern Galactic plane in such detail.

DECaPS2 is a survey of the plane of the Milky Way as seen from the southern sky taken at optical and near-infrared wavelengths. The first trove of data from DECaPS was released in 2017, and with the addition of the new data release, the survey now covers 6.5% of the night sky and spans a staggering 130 degrees in length. While it might sound modest, this equates to 13,000 times the angular area of the full Moon.

The DECaPS2 dataset is available to the entire scientific community and is hosted by NOIRLab’s Astro Data Lab, which is part of the Community Science and Data Center. Interactive access to the imaging with panning/zooming inside of a web-browser is available from the Legacy Survey Viewer, the World Wide Telescope, and Aladin.

Most of the stars and dust in the Milky Way are located in its disk — the bright band stretching across this image — in which the spiral arms lie. While this profusion of stars and dust makes for beautiful images, it also makes the Galactic plane challenging to observe. The dark tendrils of dust seen threading through this image absorb starlight and blot out fainter stars entirely, and the light from diffuse nebulae interferes with any attempts to measure the brightness of individual objects. Another challenge arises from the sheer number of stars, which can overlap in the image and make it difficult to disentangle individual stars from their neighbors.

Despite the challenges, astronomers delved into the Galactic plane to gain a better understanding of our Milky Way. By observing at near-infrared wavelengths, they were able to peer past much of the light-absorbing dust. The researchers also used an innovative data-processing approach, which allowed them to better predict the background behind each star. This helped to mitigate the effects of nebulae and crowded star fields on such large astronomical images, ensuring that the final catalog of processed data is more accurate.

“One of the main reasons for the success of DECaPS2 is that we simply pointed at a region with an extraordinarily high density of stars and were careful about identifying sources that appear nearly on top of each other,” said Andrew Saydjari, a graduate student at Harvard University, researcher at the Center for Astrophysics | Harvard & Smithsonian and lead author of the paper. “Doing so allowed us to produce the largest such catalog ever from a single camera, in terms of the number of objects observed.”

Billions of celestial objects captured in new survey of the Milky Way

Estimated read time: 2-3 minutes

ATLANTA — A new survey of the Milky Way galaxy has unveiled 3.3 billion celestial objects.

Our galaxy is brimming with hundreds of billions of stars, dark pillars of dust and gas, and gleaming stellar nurseries where stars are born. Now, astronomers have documented those wonders in unprecedented detail during the Dark Energy Camera Plane Survey, which captured 21,400 individual exposures over two years.

The survey, which marks the second data release from the program since 2017, is the largest catalog of Milky Way objects to date. The Dark Energy Camera, located on the Víctor M. Blanco 4-meter Telescope at the National Science Foundation’s Cerro Tololo Inter-American Observatory in Chile, captured the data for the survey.

The telescopes there sit at an altitude of about 7,200 feet and can observe the southern sky in great detail across visible and near-infrared wavelengths of light. The two data releases from the Dark Energy Camera Plane Survey cover 6.5% of the night sky. Astronomers will be able to use the data release to better map the 3D structure of the galaxy’s dust and stars.

“This is quite a technical feat. Imagine a group photo of over three billion people and every single individual is recognizable,” said Debra Fischer, division director of astronomical sciences at the National Science Foundation, in a statement.

“Astronomers will be poring over this detailed portrait of more than three billion stars in the Milky Way for decades to come. This is a fantastic example of what partnerships across federal agencies can achieve.”

A new image showcasing the celestial objects captured by the survey was released on Wednesday, which includes stars and dust across the Milky Way’s bright galactic disk. The galaxy’s spiral arms also lie in this plane. Together, such bright features make observing the Milky Way’s galactic plane — where most of its disk-shaped mass lies — a difficult task.

Dark streaks of dust seen in the image obscure starlight, while the glow from star-forming regions make it hard to spot the individual brightness of celestial objects.

By using the Dark Energy Camera, astronomers were able to peer through the dust of the galactic plane using near-infrared light and used a data-processing method to mitigate the obscuring effects of the star-forming regions.

The data set was shared in a study published Wednesday in the Astrophysical Journal Supplement.

“One of the main reasons for the success of DECaPS2 is that we simply pointed at a region with an extraordinarily high density of stars and were careful about identifying sources that appear nearly on top of each other,” said lead study author Andrew Saydjari, a doctoral student at Harvard University and researcher at the Harvard–Smithsonian Center for Astrophysics, in a statement.

“Doing so allowed us to produce the largest such catalog ever from a single camera, in terms of the number of objects observed.”

‘Galactic Panorama’ of Milky Way Details 3.3 Billion Celestial Objects

Astronomers have identified 3.32 billion celestial objects in the Milky Way in unprecedented detail.

The galactic panorama of stars, gas, dust and a supermassive black hole known as Sagittarius A* was captured by the U.S. National Science Foundation’s Dark Energy Camera on a 4-meter telescope. It’s housed at the Cerro Tololo Inter-American Observatory in northern Chile, which sits at an altitude of 7,200 feet, allowing for one of the clearest views of the night sky. 

“This is quite a technical feat. Imagine a group photo of over three billion people and every single individual is recognizable,” said

Debra Fischer,

division director of astronomical sciences at the National Science Foundation. “Astronomers will be poring over this detailed portrait of more than three billion stars in the Milky Way for decades to come,” she said. 

Gathering the latest batch of data from the project, known as the Dark Energy Camera Plane Survey, took over two years. It involved around 260 hours of observation with 21,000 exposures, resulting in more than 10 terabytes of data. Along with an earlier data release in 2017, the project has now covered 6.5% of the night sky.

Researchers pointed the telescope at a region of the Milky Way with “an extraordinarily high density of stars,” said

Andrew Saydjari,

a graduate student at Harvard University who worked on the project. “Doing so allowed us to produce the largest catalog ever from a single camera, in terms of the number of objects observed,” he said.

Images released in the survey show part of the Milky Way’s spiral disk, where most of the stars and dust are located. 

The team targeted a region of the Milky Way with ‘an extraordinarily high density of stars,’ a researcher said.

One small portion of the broader panoramic image is entirely filled with celestial objects, illustrating the challenges researchers faced identifying individual stars due to the sheer number that overlap one another. 

“By observing at near-infrared wavelengths, they were able to peer past much of the light-absorbing dust,” according to the Harvard-Smithsonian Center for Astrophysics, which is affiliated with the project. 

The survey data was published Wednesday in the Astrophysical Journal Supplement.

Quadrantid meteor shower: January’s first celestial event

Sign up for CNN’s Wonder Theory science newsletter. Explore the universe with news on fascinating discoveries, scientific advancements and more.



CNN
 — 

The new year kicks off with the Quadrantids, one of 12 annual meteor showers.

The celestial event is typically among the strongest meteor showers and is expected to peak overnight January 3 and 4, according to the American Meteor Society. Sky-gazers in the Northern Hemisphere can best view the shower between the late-night hours of Tuesday and dawn on Wednesday.

However, the shower is notoriously hard to observe due to its brief peak of six hours and January’s often inclement weather in the Northern Hemisphere. A bright, nearly full moon will make the Quadrantids even less visible this year.

Moonset will occur just before dawn, providing a very small window to spot the shower against dark skies.

Predictions for the shower’s peak range from 10:40 p.m. to 1:40 a.m. ET (3:40 a.m. to 6:40 a.m. Greenwich Mean Time). The later time favors those in the eastern part of North America and the earlier time is more favorable for observers across Europe. The Quadrantids won’t be visible in the Southern Hemisphere because the shower’s radiant point doesn’t rise that high in its sky before dawn.

Check Time and Date’s site to see what your chances are like to view the event, or step outside to take a look for yourself. The Virtual Telescope Project will also have a live stream of the shower over Rome.

Between 50 and 100 meteors are typically visible per hour, especially in rural areas, although the peak can include up to 120 visible meteors in an hour.

Watch the northeastern sky, and look about halfway up. You may even glimpse some fireballs during the meteor shower. View the skies for at least an hour, the American Meteor Society advises.

If you live in an urban area, you may want to drive to a place that isn’t full of bright city lights. If you’re able to find an area unaffected by light pollution, meteors could be visible every couple of minutes from late evening until dawn.

Find an open area with a wide view of the sky. Make sure you have a chair or blanket so you can look straight up. And give your eyes about 20 to 30 minutes to adjust to the darkness — without looking at your phone — so the meteors will be easier to spot.

If the meteor shower’s name sounds odd, it’s probably because it doesn’t sound like it’s related to a constellation, like other meteor showers. That’s because the Quadrantids’ namesake constellation no longer exists — at least, not as a recognized constellation.

The constellation Quadrans Muralis, first observed and noted in 1795 between Boötes and Draco, is no longer included in the International Astronomical Union’s list of modern constellations because it’s considered obsolete and isn’t used as a landmark for celestial navigation anymore, according to EarthSky.

Like the Geminid meteor shower, the Quadrantid comes from a mysterious asteroid or “rock comet,” rather than an icy comet, which is unusual. This particular asteroid is 2003 EH1, which takes 5.52 years to complete one orbit around the sun. The shower’s peak is short because only a small stream of particles interacts with our atmosphere, and the stream occurs at a perpendicular angle. Each year, Earth passes through this debris trail for a short time.

In addition to the meteor shower, a recently discovered comet will soon make its appearance in January’s night sky.

Discovered in March 2022, the comet will make its closest approach to the sun on January 12, according to NASA. The comet, spotted by astronomers using the Zwicky Transient Facility at the Palomar Observatory in San Diego County, California, is named C/2022 E3 (ZTF) and will make its closest pass of Earth on February 2.

The comet should be visible through binoculars in the morning sky for sky-watchers in the Northern Hemisphere during most of January and those in the Southern Hemisphere in early February, according to NASA.

INTERACTIVE: The best space photos of 2022

Here are the rest of 2023’s top sky events, so you can have your binoculars and telescope ready.

Mark your calendar with the peak dates of other showers to watch in 2023:

  • Lyrids: April 22-23
  • Eta Aquariids: May 5-6
  • Southern delta Aquariids: July 30-31
  • Alpha Capricornids: July 30-31
  • Perseids: August 12-13
  • Orionids: October 20-21
  • Southern Taurids: November 4-5
  • Northern Taurids: November 11-12
  • Leonids: November 17-18
  • Geminids: December 13-14
  • Ursids: December 21-22

Most years, there are 12 full moons — one for each month. But in 2023, there will be 13 full moons, with two occurring in August.

The second full moon in one month is known as a blue moon, like the phrase “once in a blue moon,” according to NASA. Typically, full moons occur every 29 days, while most months in our calendar last 30 or 31 days, so the months and moon phases don’t always align. This results in a blue moon about every 2.5 years.

The two full moons in August can also be considered supermoons, according to EarthSky. Definitions of a supermoon vary, but the term generally denotes a full moon that is brighter and closer to Earth than normal and thus appears larger in the night sky.

Some astronomers say the phenomenon occurs when the moon is within 90% of perigee — its closest approach to Earth in orbit. By that definition, the full moon for July will also be considered a supermoon event, according to EarthSky.

Here is the list of full moons for 2023, according to the Farmer’s Almanac:

  • January 6: Wolf moon
  • February 5: Snow moon
  • March 7: Worm moon
  • April 6: Pink moon
  • May 5: Flower moon
  • June 3: Strawberry moon
  • July 3: Buck moon
  • August 1: Sturgeon moon
  • August 30: Blue moon
  • September 29: Harvest moon
  • October 28: Hunter’s moon
  • November 27: Beaver moon
  • December 26: Cold moon

While these are the popularized names associated with the monthly full moon, each one carries its own significance across Native American tribes (with many also referred to by differing names).

There will be two solar eclipses and two lunar eclipses in 2023.

A total solar eclipse will occur on April 20, visible to those in Australia, New Zealand, Southeast Asia and Antarctica. This kind of event occurs when the moon moves between the sun and Earth, blocking out the sun.

And for some sky-watchers in Indonesia, parts of Australia and Papua New Guinea, it will actually be a hybrid solar eclipse. The curvature of Earth’s surface can cause some eclipses to shift between total and annular as the moon’s shadow moves across the globe, according to NASA.

Like a total solar eclipse, the moon passes between the sun and the Earth during an annular eclipse — but it occurs when the moon is at or near its farthest point from Earth, according to NASA. This causes the moon to appear smaller than the sun, so it doesn’t completely block out our star and creates a glowing ring around the moon.

A Western Hemisphere-sweeping annular solar eclipse will occur on October 14 and be visible across the Americas.

Be sure to wear proper eclipse glasses to safely view solar eclipses, as the sun’s light can be damaging to the eye.

Meanwhile, a lunar eclipse can occur only during a full moon when the sun, Earth and moon align and the moon passes into Earth’s shadow. When this occurs, Earth casts two shadows on the moon during the eclipse. The partial outer shadow is called the penumbra; the full, dark shadow is the umbra.

When the full moon moves into Earth’s shadow, it darkens, but it won’t disappear. Instead, sunlight passing through Earth’s atmosphere lights the moon in a dramatic fashion, turning it red — which is why the event is often referred to as a “blood moon.”

Depending on the weather conditions in your area, it may be a rusty or brick-colored red. This happens because blue light undergoes stronger atmospheric scattering, so red light will be the most dominant color highlighted as sunlight passes through the atmosphere and casts it on the moon.

A penumbral lunar eclipse will occur on May 5 for those in Africa, Asia and Australia. This less dramatic version of a lunar eclipse happens when the moon moves through the penumbra, or the faint, outer part of Earth’s shadow.

A partial lunar eclipse of the hunter’s moon on October 28 will be visible to those in Europe, Asia, Australia, Africa, parts of North America and much of South America. Partial eclipses occur when the sun, Earth and moon don’t completely align, so only part of the moon passes into shadow.

Stunning meteor showers, full moons and eclipses will light up the sky in 2023.

The year is sure to be a sky-gazer’s delight with plenty of celestial events on the calendar.

A comet discovered in March 2022 will make its closest approach to the sun on January 12, according to NASA. The comet, spotted by astronomers using the Zwicky Transient Facility at the Palomar Observatory in San Diego County, California, is named C/2022 E3 (ZTF) and will make its closest pass of Earth on February 2.

The comet should be visible through binoculars in the morning sky for sky watchers in the Northern Hemisphere during most of January and those in the Southern Hemisphere in early February, according to NASA.

On any given day, there is always a good chance that the International Space Station is flying overhead. And if you ever want to know what planets are visible in the morning or evening sky, check The Old Farmer’s Almanac’s calculator.

Here are the rest of 2023’s top sky events, so you can have your binoculars and telescope ready.

Most years, there are 12 full moons — one for each month. But in 2023, there will be 13 full moons, with two occurring in August.

The second full moon in one month is known as a blue moon, like the phrase “once in a blue moon,” according to NASA. Typically, full moons occur every 29 days, while most months in our calendar last 30 or 31 days, so the months and moon phases don’t always align. This results in a blue moon about every 2.5 years.

The two full moons in August can also be considered supermoons, according to EarthSky. Definitions of a supermoon can vary, but the term generally denotes a full moon that is brighter and closer to Earth than normal and thus appears larger in the night sky.

Some astronomers say the phenomenon occurs when the moon is within 90% of perigee — its closest approach to Earth in orbit. By that definition, the full moon for July will also be considered a supermoon event, according to EarthSky.

Here is the list of full moons for 2023, according to the Old Farmer’s Almanac:

  • January 6: Wolf moon
  • February 5: Snow moon
  • March 7: Worm moon
  • April 6: Pink moon
  • May 5: Flower moon
  • June 3: Strawberry moon
  • July 3: Buck moon
  • August 1: Sturgeon moon
  • August 30: Blue moon
  • September 29: Harvest moon
  • October 28: Hunter’s moon
  • November 27: Beaver moon
  • December 26: Cold moon

While these are the popularized names associated with the monthly full moon, each one carries its own significance across Native American tribes (with many also referred to by differing names).

There will be two solar eclipses and two lunar eclipses in 2023.

A total solar eclipse will occur on April 20, visible to those in Australia, Southeast Asia and Antarctica. This kind of event occurs when the moon moves between the sun and Earth, blocking out the sun.

And for some skywatchers in Indonesia, parts of Australia and Papua New Guinea, it will actually be a hybrid solar eclipse. The curvature of Earth’s surface can cause some eclipses to shift between total and annular as the moon’s shadow moves across the globe, according to NASA.

This causes the moon to appear smaller than the sun, so it doesn’t completely block out our star and creates a glowing ring around the moon.

A Western Hemisphere-sweeping annular solar eclipse will occur on October 14 and be visible across North, Central and South America.

Be sure to wear proper eclipse glasses to safely view solar eclipses, as the sun’s light can be damaging to the eye.

Meanwhile, a lunar eclipse can occur only during a full moon when the sun, Earth and moon align and the moon passes into Earth’s shadow. When this occurs, Earth casts two shadows on the moon during the eclipse. The partial outer shadow is called the penumbra; the full, dark shadow is the umbra.

The new year kicks off with the Quadrantid meteor shower, which is expected to peak in the overnight hours between January 3 and 4 for those in North America, according to the American Meteor Society.

It’s the first of 12 meteor showers throughout the year, although the next one, the Lyrid meteor shower, doesn’t peak until April.

Here are peak dates of other showers to watch in 2023:

  • Lyrids: April 22-23
  • Eta Aquariids: May 5-6
  • Southern delta Aquariids: July 30-31
  • Alpha Capricornids: July 30-31
  • Perseids: August 12-13
  • Orionids: October 20-21
  • Southern Taurids: November 4-5
  • Northern Taurids: November 11-12
  • Leonids: November 17-18
  • Geminids: December 13-14
  • Ursids: December 21-22

If you live in an urban area, you may want to drive to a place that isn’t littered with city lights. If you’re able to find an area unaffected by light pollution, meteors could be visible every couple of minutes from late evening until dawn.

Find an open area with a wide view of the sky. Make sure you have a chair or blanket so you can look straight up. And give your eyes about 20 to 30 minutes to adjust to the darkness — without looking at your phone! — so the meteors will be easier to spot.

“Magical” and rare celestial events will take place tonight as the moon eclipses Mars. Here’s how to watch.

Wednesday will be a “magical” night in the world of stargazing as four celestial events take place among the skies. 

The day will end with the earliest sunset of the year, the opposition of Mars and a rare event in which the December full moon, known as the “cold moon,” will temporarily eclipse Mars. 

According to NASA, the sun will go down just before 4:45 p.m. EST on Wednesday, with twilight ending at 5:49 p.m. EST. While it will bring early darkness, it will pave the way for a magnificent night of stargazing. Along with the full moon, viewers will be able to observe multiple planets near its glow: Jupiter, Saturn and Mars, the last of which will be directly opposite the sun, an event known as Mars opposition. 

Wednesday’s full moon is known as the cold moon because of the “long, cold nights” that winter brings, according to NASA, citing the Maine Farmers’ Almanac. It’s also known as the Frost Moon and Winter Moon in the almanac, as well as the Yule Moon and Oak Moon in Europe. 

But the main event isn’t just the moon itself. As Mars makes its closest and brightest appearance of the year, NASA said that the moon will gradually shift closer to the red planet. In some global regions, the moon will appear to eclipse Mars from view, an event known as a lunar occultation. 

“Dec. 7 brings one of those magical moments when the sky changes dramatically before your very eyes,” NASA says in a skywatching highlights video. 

Parts of North America, Europe and Northern Africa will be able to see the occultation, NASA said, while those in the southeast and east coast of the U.S. will see the moon “just graze past Mars.”

A view of the occultation should last about an hour for most people. Those in Minneapolis will see Mars disappear around 9:03 p.m. CST and reappear around 10:11 p.m., NASA said, while those in Los Angeles will be able to observe the phenomenon from around 6:31 p.m. PST to 7:31 p.m. The full moon will be at its peak at 11:08 p.m. EST.

NASA said that this event will mark a “relatively rare opportunity to watch a bright planet being occulted by the moon.”  

“The moon passes in front of planets in the night sky several times per year. In fact, it generally occults Mars itself at least a couple of times per year,” NASA said. “But each occultation is visible from only a small portion of Earth’s surface, so it’s not super common for any particular spot on Earth to see them frequently.”

For those who are outside the regions where viewing the occultation is possible, or who may not have clear skies during the celestial events, there are live streams available to watch it unfold in real time. Here’s how you can watch (all times listed below are EST): 

  • The Virtual Telescope Project 2.0 will have an online observation beginning at 11 p.m. 
  • The University of Texas at Austin’s McDonald Observatory along with Flagstaff, Arizona’s Lowell Observatory will host a live stream beginning at 9 p.m. 
  • Southern California’s Griffith Observatory will host a live stream beginning at 9 p.m. 
  • Carnegie Astronomy’s live stream will begin at 9:15 p.m.
