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 ...

Putting the squeeze on light improves gravitational wave observatories. An upgrade to one such observatory, LIGO, that comes from exploiting a quantum rule known as the Heisenberg uncertainty ...

The LIGO-Virgo-KAGRA (LVK) Collaboration has detected the merger of the most massive black holes ever observed with gravitational waves, using the US National Science Foundation-funded (NSF) LIGO ...

Installation of in-vacuum equipment as a part of the squeezed-light upgrade before Advanced LIGO’s third observing run. LIGO team members install in-vacuum equipment that is part of the squeezed-light ...

Gravitational waves—ripples in space-time caused by violent cosmic events—travel at the speed of light in every direction, eventually fading out like ripples in water. But some events are so ...

LIGO Hanford detected record-setting black hole merger, challenging current knowledge. Merged black holes spun near general relativity’s limit, baffling scientists. Funding cuts threaten U.S.

Trump budget proposal seeks to close one of two U.S. LIGO observatories by 2026. LIGO facilities detected first gravitational waves and advanced multi-messenger astronomy. Proposed closure risks ...

The LIGO Hanford Observatory near the Tri-Cities and its twin in Louisiana detected ripples of time and space passing through Earth from the most massive collision of black holes ever observed, a ...
