Black holes

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.

Two superluminous quasars, or active black holes at the centers of large galaxies, were found just 900 million years after the Big Bang — the earliest detection of a pair of merging quasars ever seen.

Stephen Hawking suggested nothing lasts forever, including black holes. Scientists may have a way to prove it at last.

Primordial black holes are one of the strongest candidates for the universe's missing dark matter. But a new theory suggests that not enough of the miniature black holes formed for this to be the case.

Stars that vanish from the sky may be collapsing directly into black holes without going supernova first, a new study of a bizarre binary star system suggests.

Researchers using NASA's Chandra X-ray telescope have found that a group of "Death Star black holes are swiveling around and pointing at new targets, like the fictional space station in Star Wars."

Scientists have calculated the speed of a spinning supermassive black hole by studying the 'spaghettified' remains of a star it destroyed.
