Black holes are regions in space where gravity is so strong that nothing, even light, can escape. Einstein's theory of ...

As black holes feed, they pull material into a disk around them. The material orbiting in this disk gets heated to extreme temperatures, and so it becomes a plasma — a state of matter in which some of ...

The biggest black holes in the Universe may be built through chains of violent mergers deep inside crowded star clusters.

Black holes are among the most extreme objects in the universe, and now scientists can model them more accurately than ever before. By combining Einstein’s gravity with realistic behavior of light and ...

Explore black hole discovery in astrophysics, from hidden stellar remnants to supermassive giants, and learn how scientists detect these invisible cosmic objects using light and gravitational waves.

As federal funding cuts impact decades of research, scientists could turn to black holes for cheaper, natural alternatives to expensive facilities searching for dark matter and similarly elusive ...

A hundred years before the Event Horizon Telescope Collaboration released the first image of a black hole in 2019—located at the heart of the galaxy M87—astronomer Heber Curtis had already discovered ...

Astronomers may have uncovered the origins of the mysterious “little red dots,” some of the strangest galaxies seen in the early universe. These tiny but brilliant objects, discovered by the James ...

In a recent piece for my column The Universe, I wrote about the biggest black holes in the cosmos. These can tip the scales at many billions of times the sun’s mass, outweighing even entire galaxies.
