The binary black holes in the universe are already astonishing enough, but researchers from the Shanghai Astronomical ...

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

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

A collision observed between two black holes, each more massive than a hundred suns, is the largest merger of its kind ever ...

The largest black hole collision ever recorded has scientists' jaws on the floor — and scratching their heads.

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

Too big to come from a dying star and too small to inhabit the center of a galaxy, these black holes are a puzzle that ...

For now, the LIGO team cannot localize where these black holes merge. But as more detectors come online in Europe, Japan and India, researchers will be better able to triangulate the sources.

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 was operational and taking data over two different periods from 2015 through 2017, with runs of 4 and 9 months in duration, respecively. The latter included an overlap, during the summer of ...

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 ...
