Read previewNASA's James Webb Space Telescope has detected three galaxies as they were likely forming during the universe's infancy, the space agency said Thursday. And it's all thanks to the tremendous observing power of the James Webb Telescope. AdvertisementThe James Webb Space Telescope helps astronomers study the very early universe. The Cosmic Dark AgesJames Webb Space Telescope has revealed 45,000 galaxies in this image, hundreds of which have never been seen until now. Astronomers study the Era of Reionization to understand the very early moments in our universe when galaxies and stars first formed and how.

Ninety percent of the mass in this cluster is dark matter. Gravity makes dark matter clump together, but dark energy counteracts this effect. Studying the density of dark matter across the cosmos will help astronomers learn how dark energy influences the structure of our universe. The telescope’s sensors make it like a net for light, Dr. Cuillandre said. “It’s very rare to find an isolated galaxy,” Dr. Cuillandre said.

In contrast to previous research that assumed the sun’s magnetic field originates from deep within the celestial body, they suspect the the source is much closer to the surface. This view of the sun's magnetic field was generated by NASA's Solar Dynamics Observatory. NASA/GSFC/Solar Dynamics ObservaModeling the sun’s magnetic fieldIt’s difficult to see the sun’s magnetic field lines, which loop through the solar atmosphere to form a complicated web of magnetic structures far more complex than Earth’s magnetic field. To better grasp how the sun’s magnetic field works, scientists turn to mathematical models. Like the 11-year solar magnetic cycle, torsional oscillations also experience an 11-year cycle.

May’s full moon is known as the flower moon, a reference to its appearance in late spring, when many flowering plants begin to bloom again after their winter slumber. The flower moon will begin to rise after sunset on Wednesday, reaching its highest point after midnight, per EarthSky. The flower moon played a minor role in a particularly dark period of US history. Martin Scorsese’s recent Oscar-nominated historical drama “Killers of the Flower Moon” explores a series of murders of Osage people in Oklahoma. The killings began in May 1921, the month of the flower moon.

Can you tell the difference between microscopic and massive? Red whirls on this rabbit’s tongue are filiform papillae, which roughen the tongue and help move food around the mouth. Purple and white “spike” proteins on this popular model of the coronavirus help it attach to and enter our cells. These might remind you of …… the clumps of cosmic debris in Tycho’s supernova, a star that may have exploded at many points simultaneously. Its concentric rings resemble …… the raging vortex at Saturn’s north pole, where green, pink and blue correspond to clouds of increasing depth.

Einstein's general theory of relativity states that the curvature of space-time causes gravity. But zoom out to enormous scales like clusters of galaxies spanning billions of light years across, and the laws of Einstein's gravity theory appear to change. A 1% adjustment may not sound like a big deal, but it's enough to suggest that Einstein's theory may need a rethink. Now, with this cosmic glitch, there's a new explanation on the table. NASA/CXC/Univ of Missouri/M.Brodwin et al; NASA/STScI; JPL/CalTechThe fact that this cosmic glitch could potentially help astronomers resolve the Hubble tension is a good sign that it may truly exist.

New research this week is adding fresh detail to one of paleontology’s biggest questions: Did dinosaur blood run hot or cold? Clues from fossilized eggshells and bones have now suggested that some dinosaurs were warm-blooded and others were not. Reinhard Dirscherl/ullstein bild/Getty ImagesMarine scientists have used artificial intelligence to decode previously unknown complexity in the calls of sperm whales. The whales produced a catalog of clicking sounds, which the researchers described as akin to a “phonetic alphabet” for sperm whales. What sperm whales are saying with their clicks remains a mystery to human ears, but understanding the scope of their vocal exchanges is an important step toward linking their calls with specific behavior.

Using telescopes capable of detecting X-rays, a team of astronomers has for the first time observed this area — called the “plunging region” — in a black hole about 10,000 light-years from Earth. The study’s findings could help astronomers better understand the formation and evolution of black holes. One thing that’s missing from the study is an actual image of the black hole, because it is too small and far away. But another team of Oxford researchers is working on something even better than a picture: the first movie of a black hole. “For example, it can be used to measure the rotation rate of the black hole,” said Reynolds, who was not involved in the study.

An international coalition of astronomers has newly discovered an unusual planet, dubbed WASP-193b, that’s about 50% bigger than Jupiter and somehow still the second lightest planet ever found. Because of how small the mass signal was, it took the team four years to gather data and calculate WASP-193b’s mass, Barkaoui explained. Eventually the team discovered the planet’s mass is a measly 14% that of Jupiter, despite being so much bigger. But a bigger size means a bigger “extended atmosphere,” said study coauthor Julien de Wit, an associate professor of planetary science at MIT. “WASP-193b is an outlier of all planets discovered to date,” he said.

But the kicker is that this giant void shouldn't exist in the first place. For example, some people have correctly argued that such a void shouldn't exist in the standard model, which is true. Cosmologists have a value, called the Hubble constant, which they use to help describe how fast the universe's expansion is accelerating. The Hubble constant should be the same value wherever you look, whether it's close by or very far away. NASA/JPL-CaltechAstronomers can't agree on what's causing this discrepancy in the Hubble constant, and the contention has become known as the Hubble tension.

Bush fires that had been on the horizon the day before were now rapidly approaching. That afternoon, from her home some miles away, Dr. Sackett watched burning embers fall from a smoky sky and worried. The fires also destroyed 500 homes across greater Canberra, and killed four people. The incident was an early warning for astronomy: Wildfires, exacerbated by climate change, were becoming a problem for their field. Since then, several other observatories have been damaged or threatened by fires and other extreme weather, and changing atmospheric conditions have made ground-based astronomical research more challenging.

The Dark Energy Camera captured a stunning image of “God’s Hand,” a cometary globule 1,300 light-years from Earth in the Puppis constellation. Cometary globules are unique because they have extended tails, like those seen on comets — but that’s the only cometlike thing about them. Astronomers still don’t know how cometary globules come to exist in such distinctive structures. The new image of the glowing red hand-like feature showcases CG 4, one of many cometary globules found across the Milky Way galaxy. The Gum Nebula is believed to contain 31 cometary globules in addition to CG 4.

In one lunar region, Japan’s “Moon Sniper” mission has beaten the odds and survived three long, frigid lunar nights since its sideways landing on January 19. The Tianwen-2 mission will visit the space rock later this decade. But first, China has set its sights on returning to the moon’s “hidden side.”An illustration depicts the far side of the moon, with Earth behind it. Since the Chang’e 4 mission in 2019, China remains the only country to have landed on the moon’s far side, sometimes called the “dark side” of the moon. Scientists hope that returning samples from the far side could solve some of the biggest remaining lunar mysteries, including the moon’s true origin.

Eta Aquariid meteor shower: How and when to watch
  + stars: | 2024-05-04 | by ( Ashley Strickland | ) edition.cnn.com   time to read: +5 min
CNN —May kicks off with the Eta Aquariid meteor shower, and experts are anticipating a better show than in recent years, according to the American Meteor Society. The Eta Aquariid shower is often considered the best meteor shower of the year for the Southern Hemisphere, where sky-watchers could see between 20 and 40 meteors each hour, or perhaps even more, according to EarthSky. The source of the Eta Aquariid meteor shower is Halley’s comet. It happens again in October, resulting in the Orionid meteor shower. The American Meteor Society is inviting spectators to share their observations of the shower, which will help astronomers determine whether there were more meteors than expected.

The space rock, known as 2016 HO3, is a rare quasi-satellite — a type of near-Earth asteroid that orbits the sun but sticks close to our planet. Astronomers first discovered it in 2016 using the Pan-STARRS telescope, or Panoramic Survey Telescope and Rapid Response System, in Hawaii. Scientists call the asteroid Kamo’oalewa, a name derived from a Hawaiian creation chant that alludes to an offspring traveling on its own. Kamo’oalewa specimen: A connecting puzzle pieceStudying crater impacts on the moon can also help scientists better understand the consequences of asteroid impacts should a space rock pose a threat to Earth in the future. There’s no other place, no other planet in our solar system with a moon like our moon.

The nebula, 3,400 light-years away in the Perseus constellation, is an expanding shell of gases kicked out by a dying red giant star. Before the aging red giant star collapsed, it released a ring of gas and dust. The companion star, once in orbit around the red giant, is nowhere to be seen in Hubble’s image. Since collapsing, the red giant star has transformed into a dead stellar remnant known as an ultra-dense white dwarf star. “The space telescope is the most scientifically productive space astrophysics mission in NASA history,” according to a NASA release.

CNN —The total solar eclipse has come and gone, but sky-gazers have reason to keep looking up — a meteor shower will peak this week right before a full moon rises. The Lyrid meteor shower will be most active Sunday night through the early morning hours of Monday, according to the American Meteor Society. And April’s full moon, also known as the pink moon, reaches the crest of its full phase at 7:49 p.m. The pink moon actually got its moniker due to its annual appearance not long after the start of spring, much like its namesake, a hot pink wildflower called Phlox subulata that blooms in early springtime, according to The Old Farmer’s Almanac. Instead, an annular solar eclipse creates a “ring of fire” in the sky as the sun’s light surrounds the moon.

Observations from the European Space Agency’s Cheops space telescope, or Characterising ExOplanet Satellite, detected a “glory effect” on WASP-76b, an ultra-hot exoplanet 637 light-years from Earth. Cheops captured data from WASP-76b as the planet passed in front of its star, making 23 observations over three years. But the glory effect is created as light moves through a narrow opening and bends, creating colorful, patterned rings. An artist's illustration shows the night-side view of the exoplanet WASP-76b, where iron rains down from the sky. Lueftinger said she believes that the James Webb Space Telescope or Ariel may be able to help prove the presence of the glory effect on WASP-76b.

A deep basin called Sputnik Planitia, which makes up the “left lobe” of the heart, is home to much of Pluto’s nitrogen ice. The New Horizons spacecraft took an image of Pluto's heart on July 14, 2015. Johns Hopkins University Applied Physics Laboratory/Southwest Research Institute/NASAThrough new research on Sputnik Planitia, an international team of scientists has determined that a cataclysmic event created the heart. The teardrop shape of Sputnik Planitia is a result of the frigidity of Pluto’s core, as well as the relatively low velocity of the impact itself, the team found. The researchers believe that the new theory regarding Pluto’s heart could shed more light on how the mysterious dwarf planet formed.

CNN —Astronomers have spotted the most massive known stellar black hole in the Milky Way galaxy after detecting an unusual wobble in space. The wobbling movement of an old giant star in the Aquila constellation revealed that it was in an orbital dance with a dormant black hole, and it’s the third such dormant black hole spotted by Gaia. So Gaia BH3 is the most massive black hole in our galaxy that formed from the death of a massive star. Stellar black holes observed across the Milky Way galaxy are about 10 times as massive as the sun on average. True to expectations, the researchers found that the star orbiting Gaia BH3 was metal-poor, which means that the star that formed Gaia BH3 was likely the same.

What to do with your solar eclipse glasses
  + stars: | 2024-04-09 | by ( Taylor Nicioli | ) edition.cnn.com   time to read: +3 min
For the fortunate folks who witnessed the rare solar event, there may not be a need to throw out gently used pairs of solar eclipse viewing glasses. That means the same glasses worn during the 2024 total solar eclipse will serve as effective protection during the next total solar eclipse in 2026 that will be visible over Greenland, Iceland, Spain, Russia and a small portion of Portugal and appear as a partial eclipse in parts of Europe, Africa and North America. Where to donate solar eclipse glassesIf the owner of a pair of solar eclipse glasses is not planning on globe-trotting to catch a glimpse of the upcoming solar eclipses, there are several organizations collecting viewers with the aim of donating to those who will be on the path of upcoming events. Eclipse Glasses USA, a retailer of eclipse glasses approved by the American Astronomical Society, is collecting used but undamaged glasses to send to schools in Chile and Argentina that will be within the path where the October 2024 annular eclipse, otherwise known as the “ring of fire,” will be visible. Astronomers Without Borders, a nonprofit organization that collected more than 2 million glasses after the 2017 total solar eclipse and redistributed hundreds of thousands of pairs before the 2024 eclipse, has a growing list of drop-off locations for donations of gently used glasses.

Editor’s note: Follow along with CNN’s live updates of the total solar eclipse. Special eclipse momentsWhile totality is considered to be the most exciting part of a total solar eclipse, there are other special phases to watch for before the big moment arrives. Amateur astronomers prepare to watch a total solar eclipse in Mazatlan, Mexico, on Monday. After the total solar eclipse ends, it’s a bit of a wait for the next such celestial sightings in the United States. Those living in Alaska will catch a glimpse of a total solar eclipse on March 30, 2033, and a partial solar eclipse will shine over most of the US during that event.

Read previewThe weeks leading up to Monday's total solar eclipse became even more exciting when astronomers announced that comet 12P/Pons-Brooks, also known as the "Devil comet," might be visible during totality. Where it all went wrongEven in the darkness of totality, I wasn't able to spot the "Devil comet" with my naked eye or my camera. But instead, I shot vaguely in the direction of where I thought the comet might be, and only captured darkness. All in all, I learned that photographing a comet with a standard DSLR is tricky. And in general, I wouldn't recommend trying to snap a picture of a comet during a total solar eclipse.

For centuries, people have been clamoring to glimpse solar eclipses. From astronomers with custom-built photographic equipment to groups huddled together with special glasses, this spectacle has captivated the human imagination. Creating a Permanent RecordIn 1860, Warren de la Rue captured what many sources describe as the first photograph of a total solar eclipse. He took it in Rivabellosa, Spain, with an instrument known as the Kew Photoheliograph. This combination of a telescope and camera was specifically built to photograph the sun.
