Black holes

Black hole singularities defy the laws of physics. New research presents a bold solution to this puzzle: Black holes may actually be a theoretical type of star called a 'gravastar,' filled with universe-expanding dark energy.

Supermassive black holes that are blasting out beams of high-energy particles killing star formation in their galaxies are shifting targets like real-life Death Stars.

Black holes are such a drag! Especially for the guts of stars they've destroyed and the fabric of spacetime they pull along with them.

For years, physicists have been looking to prove that black holes are more complex than they seem. And a newly approved European space mission called LISA will help us with this hunt.

Einstein was right! Scientists found the first-ever evidence of "plunging regions" of spacetime where matter inexorably falls into black holes, as predicted by general relativity.

The James Webb Space Telescope has detected a merger between two supermassive black holes so distant it proceeded just 740 million years after the Big Bang.

NASA's Chandra X-ray space telescope has spotted the supermassive black hole at the heart of our galaxy erupting, proving even quiet black holes like Sagittarius A* need to vent sometimes.

Some black hole pairs roll around each other in wobbly, egg-shaped orbits that could hold clues about their origins, gravitational wave measurements suggest.

NASA's Nancy Grace Roman Telescope will hunt for the universe's first stars — or rather, what's left of them after they've been ripped apart by black holes.

Astronomers find multiple streams of dust spiraling into the heart of the nearby Andromeda galaxy, where a supermassive black hole lurks.
