These are rare occurrences—scientists estimate that the giant black hole at the center of our Milky Way galaxy gobbles a star ...

On Jan. 5, 2020, astrophysicists heard a chirp from a distant part of the cosmos, some 900 million light-years away. The fleeting sound was unlike any they'd heard before and was caused by a great ...

Based on the new findings, the researchers estimate that a mash-up between a black hole and a neutron star occurs about once a month within 1 billion light-years of Earth.

Astronomers have uncovered the most promising evidence yet for the existence of dark stars—giant cosmic objects powered by dark matter, rather than the fusion processes typically seen in stars. These ...

In October 2018, astronomers witnessed a small star being ripped to shreds and swallowed when it wandered too close to a black hole in a galaxy located 665 million light years away from Earth ...

A smudge of light at the center — the flare from a dying star whose remnants are being swallowed by a black hole, suspended alone in the middle of the cosmic ocean. I smile and start planning ...

These black holes are between 100 and 1,000 times as massive as Sagittarius A* (Sgr A*), the supermassive black hole at the heart of the Milky Way that sits just 26,000 light-years from Earth.

The search for dark matter requires all the best models, theories, and ideas we can throw at it. A new paper by Julia Monika ...

Astronomers have detected the signal of a colossal black hole in deep space that likely formed when two already-large black ...
