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

A U.S. gravitational wave detector spotted a collision between fast-spinning “forbidden” black holes that challenge physics ...

The massive black hole has been dubbed GW231123. Its unusual size and behavior is challenging scientists' understanding of ...

Gravitational-wave detectors have captured their biggest spectacle yet: two gargantuan, rapidly spinning black holes likely ...

An international team of physicists discovered the largest-ever merger of 2 black holes through a phenomenon known as gravitational waves.

Two colossal black holes—among the most massive ever seen—collided in deep space, creating gravitational waves that rippled across the cosmos and shook the foundations of astrophysical theory.

The Laser Interferometer Gravitational-wave Observatory (LIGO) is no stranger to making history and breaking records. In 2015 ...

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

It took less than a second for the space observatory hidden in Louisiana woods to detect a black hole that is that is ...

New gravitational wave findings from the LIGO-Virgo-KAGRA Collaboration report the discovery of the largest black hole merger ...

The biggest black hole merger yet observed could confirm a rare class of black holes long thought to be missing from the universe.

To date, the collaboration has detected dozens of merger events since its first Nobel Prize-winning discovery. Early detected ...
