Black holes

A potential intermediate-mass black hole is hiding right next to our galaxy's supermassive black hole.

Black hole growth is slowing down, suggests a team of astrophysicists who looked back in time across the universe's 13.8 billion-year history.

Black holes aren't "cosmic vacuum cleaners," but what would happen if one wandered into our solar system?

Seven strangely-behaving stars in the Milky Way's Omega Centauri cluster may be under the influence of an extremely rare type of black hole, new research suggests.

Using the James Webb Space Telescope, astronomers have witnessed the dramatic dance between a supermassive black hole-powered quasar and merging galaxies less than a billion years after the Big Bang.

New theoretical research finds that it's impossible to form a black hole with the energy of light particles alone, poking a hole in Einstein's theory of general relativity.

The James Webb Space Telescope found "tiny red dots" in the early universe representing overgrown supermassive black holes and stars that are impossibly old for the infant cosmos.

Using the James Webb Space Telescope, astronomers have discovered an improbably huge black hole near the dawn of time, which doesn't seem to be eating near as much as it should.

A gargantuan "exhaust vent" may be channeling hot gas away from the Milky Way's supermassive black hole at millions of miles per hour — and filling up two enormous bubbles that tower over the galaxy.

Astronomers may be watching a supermassive black hole "waking up" from a long slumber for the first time ever. The researchers think the black hole may have gotten its hands on a glut of new material to devour, causing an uptick in brightness.
