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.

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

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

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

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

The Trump administration has called for shutting down either a Tri-Cities, WA, or Louisiana observatory that work in tandem.

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

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 ...
