Gravitational waves spotted by LIGO reveal two black holes, 140 and 100 times the mass of the sun, merged to become a 225 solar mass behemoth.

Scientists have witnessed evidence of a collision between black holes so huge that it defies their understanding of physics.

A puzzling gravitational wave was detected, and astronomers have determined that it comes from a record-breaking black hole ...

The powerful merger, designated GW231123, produced an extremely large black hole about 225 times the mass of our Sun.

But in the past two decades, new types of black holes have been seen and astronomers are beginning to understand how they ...
