Black holes

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

Einstein's general theory of relativity predicted that so-called 'plunging regions' around black holes would accelerate matter into them at the speed of light. Now, X-ray observations of a remote black hole have proved him right.

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.

What would it be like to fall past the event horizon of a black hole? A new NASA simulation provides a peek into the bizarre physics of spaghettification.

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.

Astronomers found the most massive stellar-mass black hole in the galaxy after spotting a star "wobbling" nearby. The baby monster is the 2nd-closest black hole to Earth ever detected.

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.

A new polarized light image of the supermassive black hole Sagittarius A* has given us our first clear look at the magnetic field of the cosmic juggernaut, which suggests that it may have superheated jets just like even larger black holes.
