Our galaxy may reside in a billion-light-year-wide cosmic bubble that accelerates local expansion, potentially settling the long-running Hubble tension. Galaxy counts reveal a sparsely populated neighborhood,...
New supercomputer simulations suggest the Milky Way could be surrounded by dozens more faint, undetected satellite galaxies—up to 100 more than we currently know. These elusive...
Scientists from UCL and the University of Cambridge have revealed that "space ice"—long thought to be completely disordered—is actually sprinkled with tiny crystals, changing our fundamental...
Astronomers using the Green Bank Telescope spotted surprisingly cold, dense hydrogen clouds embedded inside the Milky Way’s vast, super-hot Fermi bubbles—structures thought to be created by...
Astronomers studying the remnant SNR 0509-67.5 have finally caught a white dwarf in the act of a rare “double-detonation” supernova, where an initial helium blast on...
UF engineers, backed by DARPA and NASA, are perfecting laser-forming techniques that let metal sheets fold themselves into giant solar arrays, antennas, and even space-station parts...
Citizen scientists using the Kilonova Seekers platform spotted a stellar flash 2,500 times brighter than before, allowing astronomers to identify the exploding cataclysmic variable GOTO0650 within...
A surprising discovery from a tiny grain of asteroid Ryugu has rocked scientists' understanding of how our Solar System evolved. Researchers found djerfisherite—a mineral typically born...
Scientists are peering into the universe's mysterious Cosmic Dawn using the faint whispers of hydrogen radio waves emitted over 13 billion years ago. These signals, particularly...
A stunning breakthrough in solar physics reveals ultra-fine magnetic structures on the Sun's surface, thanks to the NSF's Inouye Solar Telescope. Researchers captured never-before-seen bright and...
