black holes

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.

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.

New observations with the James Webb Space Telescope reveal the most distant pair of merging black holes ever spotted. The discovery further challenges leading theories of cosmology.

Astronomers using the James Webb Space Telescope have separated the light of a quasar from the light of its surrounding stars, offering unprecedented insight into how the universe's oldest black holes grew.

Supermassive black holes may create conditions akin to "cosmic intersections with failed traffic lights" that make collisions between smaller stellar-mass black holes inevitable.

An explosive flare from the Milky Way's central black hole has been translated from 'a single flickering pixel' into a detailed 3D model using AI and Einstein's general relativity equations.

Could dark matter be made of mini black holes that formed in the early universe? One way to find out is to look for missing stars, destroyed by primordial black holes, a new study suggests.

Scientists found a monster black hole that 'hiccups' every 8.5 days, and a smaller black hole that keeps punching through its accretion disk may be to blame.
