'A collision within a collision': Neutron star merger hiding in mini-galaxy could answer 2 big astrophysics questions
A powerful "gamma-ray burst" has been seen exploding from merging neutron stars hidden within a previously unknown mini-galaxy leftover from an ancient cosmic crash. The "collision within a collision" could help answer multiple astrophysics questions, researchers say.
Enormous 3D map of the universe shows brilliant 'sea of light' near the cosmic dawn
A unique technique allowed astronomers to see the early universe as a "sea of light" and explore the effects of gravity and dark energy on cosmic evolution.
'Truly extraordinary': Mega-laser shooting at us from halfway across the universe is the brightest 'cosmic beacon' we've ever seen
Astronomers have discovered the brightest and most distant "megamaser" to date. The cosmic energy beam is shooting toward Earth from 8 billion light-years away and was spotted thanks to a weird space-time trick first predicted by Einstein.
Deepest views from James Webb and Chandra reveal monster object that defies theory — Space photo of the week
The James Webb Space Telescope and the Chandra X-ray Observatory have captured the clearest image yet of a galaxy cluster in the making, seen when the universe was only one billion years old.
AI spots 'jellyfish,' 'hamburgers' and other unexplainable objects in Hubble telescope data
AI helped researchers probe the Hubble Space Telescope's archive to find strange celestial objects, including some indescribable by science.
Dark matter and neutrinos may interact, hinting at 'fundamental breakthrough' in particle physics
Astronomers found evidence that dark matter and neutrinos may interact, hinting at a "fundamental breakthrough" that challenges our understanding of how the universe evolved.
Strange, 'starved' galaxy died 'a death of 1,000 cuts' in the ancient universe, JWST reveals
A supermassive black hole embedded in an early galaxy likely starved the galaxy of gas needed to form young stars, new observations revealed.
Oddball 'platypus galaxies' spotted by James Webb telescope may challenge our understanding of galaxy formation
Astronomers spotted nine galaxies with characteristics that have never been seen as a collection before. It's possible this is a newly found type of star-forming galaxy.
