The merger wasn’t just the biggest ever, but also an event so rare that it challenges existing models for black hole genesis.

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

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

Long ago, in a galaxy far away, two black holes danced around each other, drawing ever closer until they ended in a cosmic collision that sent ripples through the fabric of spacetime. On September 14, ...

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

LIGO changed that. Last year, the collaboration announced that its twin detectors had picked up a passing distortion in late 2015 caused by two black holes crashing into each other.

Gravitational-wave detectors have captured their biggest spectacle yet: two gargantuan, rapidly spinning black holes likely forged by earlier smash-ups fused into a 225-solar-mass titan, GW231123. The ...

When LIGO detected gravitational waves for the first time, we were delighted, but we weren't surprised. Theorists had calculated exactly the type of LIGO-sensitive signal that should result from ...

As LIGO's sensitivity becomes better and better, and as more detectors come online, our capabilities allow us to detect more of these waves, and the cataclysmic events that generate them, ...

LIGO detected gravitational waves created from the collision between two black holes. The detection was awesome, but let's look at the name of the detector for a second: Laser Interferometer ...

LIGO’s twin detectors are placed 3,000 miles apart so that any signals can be verified and triangulated. The designs are virtually identical.

LIGO’s first catch was a pair of colliding black holes, each around 30 times the mass of the sun (SN: 3/5/16, p. 6). The experiment detected vibrations from the merging black holes on ...
