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

Gravitational-wave detectors have captured their biggest spectacle yet: two gargantuan, rapidly spinning black holes likely forged by earlier smash-ups fused into a 225-solar-mass titan, GW231123 ...

Scientists have detected the merger of the most massive black holes ever observed with gravitational waves, using the US National Science Foundation-funded (NSF) LIGO Hanford and Livingston ...

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 ...

The Laser Interferometer Gravitational-Wave Observatory (LIGO)'s LIGO-Virgo-KAGRA (LVK) collaboration has detected an ...

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

The merger wasn’t just the biggest ever, but also an event so rare that it challenges existing models for black hole genesis.
