This is the most massive black hole binary we’ve observed through gravitational waves, and it presents a real challenge to ...

The LIGO Hanford Observatory near the Tri-Cities and its twin in Louisiana detected ripples of time and space passing through ...

A gravitational wave has revealed the biggest black-hole merger ever recorded—so massive and extreme, it defies current astrophysical models. The clash formed a 225-solar-mass monster, possibly made ...

Gravitational-wave detectors have captured their biggest spectacle yet: two gargantuan, rapidly spinning black holes likely ...

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

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 ...
