ALMA Detects Oxygen in Farthest Known Galaxy
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have detected oxygen in the most distant confirmed galaxy ever found, JADES-GS-z14-0. This detection, made by two different teams, suggests the galaxy is much more chemically mature than expected. This is an artist’s impression of JADES-GS-z14-0. Image credit: ESO / M. Kornmesser. Discovered in 2024, JADES-GS-z14-0 (GS-z14
Atacama Cosmology Telescope Captures Clearest Images Yet of Cosmic Microwave Background
New images from the Atacama Cosmology Telescope (ACT) reveal the Universe when it was about 380,000 years old.

75 Laboratory-Classified Meteorites Traced to Their Parent Asteroids in Main Belt
Astronomers from SETI Institute, NASA’s Ames Research Center and Curtin University have traced the impact orbit of 75 observed meteorite falls to several previously unidentified source regions in the main asteroid belt.

30,000-Year-Old Fossil Feathers of Griffon Vulture Found in Italy
Fossil feathers are usually preserved as carbonaceous films and impressions in lacustrine and marine sediments, or embedded in amber, but rarely mineralized. In a new study, paleontologists examined mineralized plumage of a 30,000-year-old griffon vulture preserved in ash-rich volcanic sediments of the Colli Albani volcanic complex, Rome, Italy. The bird’s feathers were preserved in three
Miocene-Period Freshwater Fish Had Opportunistic Benthopelagic Diet
Paleontologists from the Australian Museum Research Institute, the University of New South Wales, the University of Canberra and CSIRO have described a new species of osmeriform fish from the fossilized remains found in New South Wales, Australia; preserved stomach contents of the fish indicate an opportunistic benthopelagic diet, evidenced by the remains of numerous phantom
