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

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 ...

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

In March 2023, the gravitational wave detector LIGO will resume operations with increased sensitivity as it searches for the ripples in space-time triggered by violent events such as black hole ...

LIGO’s 20-month observation run 04 will officially start on May 24, and it will later be joined by Virgo and a new Japanese observatory—the Kamioka Gravitational Wave Detector, or KAGRA.
