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 ...

But most intriguing to the scientists are the two black holes' masses: approximately 100 and 140 times that of the sun. As was the case with the previous detection, black holes of these sizes fall ...

The observatory in Livingston Parish that made a historic scientific breakthrough by detecting gravitational waves is now at risk of shutting down under the Trump administration's proposed federal ...

Back in 2019, the gravitational wave observatories LIGO and Virgo detected major ripples in spacetime. While astronomers generally agree that the event, dubbed GW190521, was the result of two black ...

On Sept. 14, 2015, physicists attained the long-sought goal of detecting gravitational waves, the shockwaves spewed out by such cataclysmic events as the violent merger of two black holes. Now, in the ...

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 ...

The Laser Interferometer Gravitational Wave Observatory (LIGO) has seen over 300 black hole mergers in its short time in operation, and now it’s seen an event so large—and so rare—that it challenges ...
