LIGO, the Laser Interferometer Gravitational-wave Observatory, has been called the most precise ruler in the world for its ...

LIGO Hanford engineers swap out a fiber cable in a vacuum squeezer during the October 2019 commissioning break at the observatory near Richland, Wash., one of two in the nation.

LIGO Hanford observatory, Richland, Washington, should detect gravitational waves from more mergers in space after quantum limit breakthrough.

GW190814’s gravitational waves suggest a hidden supermassive black hole nearby. The finding reshapes how binary black holes may form. Binary black holes are already among the universe’s most ...

An analysis by the international LIGO (Laser Interferometer Gravitational-Wave Observatory) Scientific Collaboration to be submitted to Astrophysical Journal Letters has shown that no more than 4 ...

Scientists believe if the Trump administration's proposed budget is approved, a Louisiana space observatory could be on the chopping block and "cripple" its scientific mission.

Gravitational waves detected at LIGO Hanford Observatory in Washington reveal a puzzling black hole merger, the heaviest detected. Trump calls for LIGO closure.

The LIGO Hanford observatory near Richland has detected gravitational waves in space from 4 more black hole collisions. The black hole detections were in collaboration with Virgo and LIGO Livingston.
