Radio observatories across the globe have found compelling evidence for the existence of very-low-frequency gravitational waves.
Massive, dying stars — behemoths tens of times the Sun's mass — should emit gravitational waves that we can hear with LIGO.
Duos of supermassive black holes tangoing throughout the universe make their own music, and astronomers may have picked up a hint of the tune.
Gravitational-wave scientists have unveiled their latest catalog of events, revealing a surprising number of massive black holes.
Gravitational-wave observatories have detected the most massive black hole merger yet, and it's challenging our ideas of black hole formation.
Astronomers have caught a black hole colliding with a mysterious companion that might be either one of the most massive neutron stars or the smallest black hole ever detected.
Scientists with the Laser Interferometer Gravitational-wave Observatory (LIGO) and Virgo collaborations have announced the detection of a second pair of neutron stars that went bump in the night.
A re-analysis of data from LIGO and Virgo brings the number of gravitational-wave detections to 11, including the most distant and most powerful black-hole merger yet discovered.
A new finding suggests that LIGO’s neutron-star merger was a typical gamma-ray burst after all.
