Astronomers find first emission spectra in brightest GRB of all time
Chance that first detected emission line is a noise fluctuation is one in half a billion. Enlarge / A jet of particles moving at nearly light-speed emerges from a massive star in this artist’s concept of the BOAT. (credit: NASA.....»»
New study disputes Hunga Tonga volcano"s role in 2023–24 global warm-up
New research from a collaborative team featuring Texas A&M University atmospheric scientist Dr. Andrew Dessler is exploring the climate impact of the 2022 Hunga Tonga volcano eruption and challenging existing assumptions about its effects in the proc.....»»
Fermi Telescope finds new feature in brightest gamma-ray burst yet seen
In October 2022, astronomers were stunned by what was quickly dubbed the BOAT—the brightest-of-all-time gamma-ray burst (GRB). Now an international science team reports that data from NASA's Fermi Gamma-ray Space Telescope reveals a feature never s.....»»
Webb images nearest super-Jupiter, opening a new window to exoplanet research
Using the James Webb Space Telescope (JWST), an MPIA-led team of astronomers imaged a new exoplanet that orbits a star in the nearby triple system Epsilon Indi. The planet is a cold super-Jupiter exhibiting a temperature of around 0 degrees Celsius a.....»»
Female whale shark with satellite transmitter for record-breaking four years shows consistent migrations
A team of researchers at the University of Rhode Island and Nova Southeastern University in Florida have been tracking a 26-foot endangered whale shark—named "Rio Lady"—with a satellite transmitter for more than four years—a record for whale sh.....»»
Surprise blast of rock, water and steam in Yellowstone sends dozens running for safety
A surprise eruption in Yellowstone National Park shot steam, water and dark-colored rock and dirt high into the sky Tuesday and sent sightseers running for safety......»»
Seafloor sediment reveals previously unknown volcanic eruption 520,000 years ago in south Aegean Sea
"Core on deck!" For two months, whenever I heard that cry, I would run up to the deck of the JOIDES Resolution to watch the crew pull up a 30-foot (10-meter) cylindrical tube filled with layered, multicolored rock and sediment drilled from the seaflo.....»»
Astronomers discover technique to spot AI fakes using galaxy-measurement tools
Researchers use technique to quantify eyeball reflections that often reveal deepfake images. Enlarge / Researchers write, "In this image, the person on the left (Scarlett Johansson) is real, while the person on the right is AI-ge.....»»
Saturday Citations: Scientists study monkey faces and cat bellies; another intermediate black hole in the Milky Way
This is not a rerun of last week's roundup; another group of astronomers found a second intermediate-mass black hole in the Milky Way and I can't avoid highlighting it. They're cool! They may have formed in the primordial universe, they comprise the.....»»
New dawn for space storm alerts could help shield Earth"s tech
Space storms could soon be forecast with greater accuracy than ever before thanks to a big leap forward in our understanding of exactly when a violent solar eruption may hit Earth......»»
Introducing Ramses, ESA"s 2029 mission to asteroid Apophis
Thirty years ago, on 16 July 1994, astronomers watched in awe as the first of many pieces of the Shoemaker-Levy 9 comet slammed into Jupiter with incredible force. The event sparked intense interest in the field of planetary defense as people asked:.....»»
Observations detect a nearby hypervelocity stellar/substellar object
Using the Keck II telescope, astronomers have detected an object that may be a brown dwarf or a low-mass star, exhibiting a very high radial velocity. The object, designated CWISE J124909.08+362116.0 is located some 400 light years away. The finding.....»»
Pompeii skeleton discovery shows another natural disaster may have made Vesuvius eruption even more deadly
Almost 2,000 years ago, Pliny the Younger wrote letters describing the shaking ground as Vesuvius erupted. Now, a collaborative study led by researchers from the Istituto Nazionale di Geofisica e Vulcanologia (INGV) and Pompeii Archaeological Park ha.....»»
Astronomers spot a "highly eccentric" planet on its way to becoming a hot Jupiter
Hot Jupiters are some of the most extreme planets in the galaxy. These scorching worlds are as massive as Jupiter, and they swing wildly close to their star, whirling around in a few days compared to our own gas giant's leisurely 4,000-day orbit arou.....»»
Exoplanet caught in "hairpin turn" signals how high-mass gas giants form
Astronomers have discovered a planet that has the most oblong orbit ever found among transiting planets. The exoplanet's extreme circuit—which looks closer to a cucumber than a circle—follows one of the most drastically stretched-out orbits of al.....»»
Astronomers detect dozens of new pulsating white dwarfs
Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have detected 32 new bright pulsating DA white dwarfs of the ZZ Ceti subclass. The finding was reported in a research paper published July 9 on the pre-print server arXiv......»»
Astronomers discover what may be 21 neutron stars orbiting sun-like stars
Most stars in our universe come in pairs. While our own sun is a loner, many stars like our sun orbit similar stars, while a host of other exotic pairings between stars and cosmic orbs pepper the universe. Black holes, for example, are often found or.....»»
Telescope tag-team discovers 10 strange and exotic pulsars
Towards the center of our Milky Way galaxy, in the constellation Sagittarius, astronomers have discovered 10 monstrous neutron stars. These particular stars, called pulsars, reside together in globular cluster Terzan 5, a crowded home for hundreds of.....»»
Scorching storms on distant worlds revealed in new detail
Astronomers have created the most detailed weather report so far for two distant worlds beyond our own solar system. The international study—the first of its kind—reveals the extreme atmospheric conditions on the celestial objects, which are swat.....»»
