New supercomputer simulations suggest the Milky Way could be surrounded by dozens more faint, undetected satellite ...

When white dwarfs—the hot remnants of stars like our sun—are orbited closely by another star, they sometimes steal mass away ...

The precursors of heavy elements might arise in the plasma underbellies of swollen stars or in smoldering stellar corpses.

The search for dark matter requires all the best models, theories, and ideas we can throw at it. A new paper by Julia Monika Koulen, Stefano Profumo, and Nolan Smyth from the University of California ...

In the first study of its kind, researchers at the RIKEN Center for Interdisciplinary Theoretical and Mathematical Sciences (iTHEMS) in Japan, along ...

If you don’t have a nearby pool or body of water to cool down, you may have to resort to other things to beat the Texas heat.

The James Webb Space Telescope has captured an exoplanet no one had seen before. This marks a turning point in space ...

Scientists predict up to 100 invisible galaxies may orbit the Milky Way, hiding just beyond our current detection limits.

New simulations reproduce high-redshift galaxies seen by JWST and propose a radical cosmological shift beyond ΛCDM. To simulate the universe with ...
