Black holes

The James Webb Space Telescope has discovered lonely quasars in the early universe, with "empty larders" that defy theories surrounding their growth to monster sizes.

Researchers spotted a second distant star orbiting a well-known black hole and its stellar companion in a never-before-seen gravitational triad. The system's unique configuration suggests that the black hole was not created as scientists initially expected.

New research can help us understand how supermassive black holes formed — and why many of them appear to be more massive than expected.

Star explosions called novas are happening twice as often near a gargantuan black hole jet as they are in the rest of the galaxy, and astronomers aren't sure why.

"If there are lots of black holes out there, some of them must surely pass through our backyard every now and then."

The largest-ever black hole jets ever seen hint that these cosmic monsters may play an even more significant role in shaping galaxies than previously thought.

New observations with JWST have confirmed that supermassive black holes have the power to quench star formation across their surrounding galaxies.

Observations from the Event Horizon Telescope may reveal a secret merger in our supermassive black hole's past, potentially explaining the cosmic monster's unusual spin.

By using protons to probe how a magnetic field responds to an expanding plasma, experimenters have replicated the particle jets spewed out by active black holes.

A tiny fraction of known black holes emit X-ray signals that resemble a human "heartbeat." Now, new research may finally explain the strange phenomenon.
