At 225 solar masses, this gargantuan merger of two black holes challenges our thinking on these famously elusive objects.

Scientists have made a terrifying discovery: two black holes are on a collision course, set to merge into a massive hole that’s more than 225 times the size of the sun. If that isn’t scary enough, ...

Christopher Nolan's 2014 sci-fi movie gets analyzed by a real astrophysicist, who sings the movie's praises despite occasional errors.

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

A new hypothesis called the “quantum memory matrix” could solve long-standing physics questions, including the Black Hole Information Paradox and dark matter.

When black holes collide, they temporarily form one lumpy and unstable large black hole that needs to settle down into a simple, round shape.

The second way that supermassive black holes grow is through mergers, where two supermassive black holes collide and merge together to form a single, even more massive, black hole.

NASA finds supermassive black hole called ‘Space Jaws:’ Why it deserves sci-fi horror name A sneaky black hole was the source of a tidal disruption event that was so large and so bright that ...

A monstrous black hole in a distant galaxy has earned itself a nickname worthy of a science-fiction horror movie for its gluttonous feasting on any stars that dare get near. Meet "Space Jaws ...

Collisions between black holes can launch newly melded cosmic sinkholes at speeds up to nearly one-tenth the speed of light, researchers report August 18 in Physical Review Letters.

Using NASA’s James Webb Space Telescope, Northwestern astrophysicists gained the longest, most detailed glimpse yet of the supermassive black hole at the center of the Milky Way.
