In this instance, two enormous black holes – 100 and 140 times the mass of Earth's sun – collided. The result? A black hole the size of a whopping 240 suns. Black holes this massive shouldn't be ...

Physicists with the LIGO/Virgo/KAGRA collaboration have detected the gravitational wave signal (dubbed GW231123) of the most massive merger between two black holes yet observed, resulting in a new ...

Two colossal black holes among the most massive ever seen collided in deep space, creating gravitational waves that rippled across the cosmos and shook the foundations of astrophysical theory.

Senate bill includes funding to keep both U.S. LIGO observatories operational. LIGO confirmed 300 gravitational wave events since Nobel-honored 2015 discovery. Sen. Murray worked to save LIGO by ...
