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,...
Gravitational-wave detectors have captured their biggest spectacle yet: two gargantuan, rapidly spinning black holes likely forged by earlier smash-ups fused into a 225-solar-mass titan, GW231123. The...
Imagine a star powered not by nuclear fusion, but by one of the universe’s greatest mysteries—dark matter. Scientists have proposed the existence of “dark dwarfs,” strange...
China's Chang’e-6 mission has delivered the first-ever samples from the Moon’s far side, shedding light on one of planetary science’s greatest mysteries: why the near and...
Using the James Webb Space Telescope, scientists spotted thin and thick disks in galaxies as far back as 10 billion years ago—something never seen before. These...
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...
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...
Astronomers have uncovered a colossal, searing-hot filament of gas linking four galaxy clusters in the Shapley Supercluster a discovery that could finally solve the mystery of...
Astronomers have produced the most detailed map yet of the Sculptor Galaxy, revealing hundreds of previously unseen celestial features in stunning color and resolution. By combining...
Surveying nearby galaxies in the process of merging with other galaxies, astronomers have identified massive, dense star factories, unlike any found in the Milky Way. The...
