A puzzling gravitational wave was detected, and astronomers have determined that it comes from a record-breaking black hole ...

A record-breaking black hole collision has stunned scientists with its sheer scale and speed. Detected by the LIGO-Virgo-KAGRA observatories, the event merged two enormous black holes—each over 100 ...

Less than a decade since the first detection of gravitational waves—ripples in spacetime itself—proposed budget cuts threaten ...

The massive black hole has been dubbed GW231123. Its unusual size and behavior is challenging scientists' understanding of ...

Scientists at the LIGO Hanford Observatory have made a groundbreaking discovery by observing the largest black hole merger ever recorded through gravitational waves.

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 ...

At 225 solar masses, this gargantuan merger of two black holes challenges our thinking on these famously elusive objects.

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 ...

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

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 ...

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