Astronomers have explained how a galaxy cluster maintains its heat, despite emitting X-rays that cool the hot gas at its center. The group discovered the existence of a fast-moving, high-temperature ...

Physicists have unveiled a new way to simulate a mysterious form of dark matter that can collide with itself but not with ...

Six years of Dark Energy Survey observations combine four cosmological probes to refine measurements of cosmic expansion, dark energy behavior, and matter clustering across billions of years.

The discovery reinforces established theories about space. There could be many more satellite galaxies orbiting the Milky Way than previously thought or observed, according to astronomers. As many as ...

Scientists have observed the largest-known rotating structure in the cosmos, a gargantuan thread-like assemblage of hundreds of galaxies, gas and dark matter that makes up a filament in the ...
