Less than a decade since the first detection of gravitational waves—ripples in spacetime itself—proposed budget cuts threaten ...

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

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 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 ...

Joseph Giaime, head of the observatory, joined Louisiana Considered to talk to us about the event’s significance, and how ...

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

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

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

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

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

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.
