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

The future of at least one of the U.S. LIGO observatories is in jeopardy as deep cuts to science programs are proposed by the ...

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

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

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 ...

On May 24, scientists at the Laser Interferometer Gravitational-Wave Observatory (LIGO) began an 18-month campaign to detect the most distant collisions between black holes and neutron stars ...
