The international LIGO-Virgo-KAGRA Collaboration reports the observations of two record-breaking events in gravitational wave ...

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 ...

The findings confirm the presence of rare binary systems and suggest certain black holes are second-generation, forged in ...

Ten years ago, astronomers made an epic discovery with the Laser Interferometer Gravitational-Wave Observatory. Cosmology hasn’t been the same since, and it might not stay that way much longer. Out ...

Ten years after the historic discovery of gravitational waves, and having spotted hundreds more of these space-time swells since then, physicists say they are only just getting started. On 14 ...

It took less than a second for the space observatory hidden in Louisiana woods to detect the most massive black hole ever observed. Only one tenth of a second to be exact. That's how long it took for ...

The detection, made by the Laser Interferometer Gravitational-wave Observatory (LIGO) on Jan. 14, provides the best evidence yet for a theory put forth by famed physicist Stephen Hawking more than ...

As scientists at the Laser Interferometer Gravitational-wave Observatory resume their search for ripples in the fabric of space-time, the awards for their discoveries continue to stack up. On Monday, ...
