Second Detection of Gravitational Waves

On December 26, 2015 at 03:38:53 UTC, the twin detectors of the Laser Interferometer Gravitational-wave Observatory (LIGO) observed gravitational waves produced by the collision of two stellar-mass black holes. The black holes that emitted these waves are inferred to have masses of 14 and 8 solar masses, and the final black hole has a mass of 21 solar masses. This event, named GW151226,…

First Evidence for Binary Black Hole Mergers

The gravitational waves detected on September 14, 2015 at 09:50:45 UTC from the two detectors of the Laser Interferometer Gravitational-Wave Observatory (LIGO) is first observation of a binary black hole merger. The initial black holes are found to have individual masses of 29 and 36 solar masses and merged to form a single black hole with a mass of 62 solar masses. The merger occurred at a…

Gravitational Waves Detected

LIGO scientist David Reitze takes us on a 1.3 billion year journey that begins with the violent merger of two black holes in the distant universe. The event produced gravitational waves, tiny ripples in the fabric of space and time, which LIGO detected on September 14, 2015, as they passed Earth.
