Astronomers discover two new super-Earths orbiting nearby stars
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has detected two new super-Earth exoplanets orbiting nearby M-dwarf stars. The newfound exoplanets, designated TOI-6002 b and TOI-5713 b, are two times la.....»»
Newly-discovered star could provide new insights into the evolution of stars
A new study published in The Astrophysical Journal, led by Assistant Professor of Astronomy Rana Ezzeddine and UF alumnus Jeremy Kowkabany, with collaborators, reports the discovery of a star that challenges astronomers' understanding of star evoluti.....»»
Take a trip to the largest lake on Mars
Mars once hosted a lake larger than any on Earth. The broken-down and dried-up remnants of this ancient lakebed are shown here in amazing detail by ESA's Mars Express......»»
Image: Doomed star Eta Carinae
Eta Carinae may be about to explode. But no one knows when—it may be next year, it may be 1 million years from now. Eta Carinae's mass—about 100 times greater than our sun—makes it an excellent candidate for a full blown supernova......»»
Astronomers discover new supergiant-rich stellar cluster
Astronomers report the discovery of a new galactic stellar cluster located some 24,000 light years away. The newfound cluster, which received the designation Barbá 2, turns out to host at least several supergiant stars. The finding was detailed in a.....»»
Scientists pin down the origins of the moon"s tenuous atmosphere
While the moon lacks any breathable air, it does host a barely-there atmosphere. Since the 1980s, astronomers have observed a very thin layer of atoms bouncing over the moon's surface. This delicate atmosphere—technically known as an "exosphere"—.....»»
Astronomers use AI to find elusive stars "gobbling up" planets
Astronomers have recently found hundreds of "polluted" white dwarf stars in our home galaxy, the Milky Way. These are white dwarfs caught actively consuming planets in their orbit. They are a valuable resource for studying the interiors of these dist.....»»
TIC 441725813 is a hybrid pulsating subdwarf star, study finds
Astronomers have employed NASA's Transiting Exoplanet Survey Satellite (TESS) to observe a subdwarf star designated TIC 441725813. In result, they found that TIC 441725813 is a hybrid hot B subdwarf pulsator. The discovery was detailed in a research.....»»
How Kepler’s 400-year-old sunspot sketches helped solve a modern mystery
A sharp decline in sunspot activity in the 17th century has long puzzled astronomers. Enlarge / A naked-eye sunspot group on May 11, 2024. There are typically 40,000 to 50,000 sunspots observed in ~11-year solar cycles. (credit:.....»»
Astronomers explain rapid formation of organic macromolecules in protoplanetary disks around young stars
An international team of researchers led by the University of Bern has used observation-based computer modeling to find an explanation for how macromolecules can form in a short time in disks of gas and dust around young stars. These findings could b.....»»
Globular cluster NGC 6558 explored with Gemini Observatory and Hubble Space Telescope
Using the Gemini Observatory and the Hubble Space Telescope (HST), an international team of astronomers has investigated a Galactic globular cluster known as NGC 6558. Results of the new study, published July 22 on the pre-print server arXiv, deliver.....»»
Astronomers find first emission spectra in brightest GRB of all time

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.....»»
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
