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

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

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 ...

Learn more about LIGO, the observatory that detected two massive black holes merging, the largest in recorded history.

Gravitational wave detectors have "heard" the ripples in space caused by the most massive black hole merger yet. One ...

And LIGO’s second gravitational wave event, GW151226, is great for both! Essentially, on the pessimist’s side, GW151226 makes it all-but-certain that LIGO is picking up genuine gravitational ...

There are two LIGO detectors. One is in Louisiana (only 30 minutes from where I live) and the other is in Washington. Other gravitational wave detectors exist on Earth, but they were not ...
