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

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

When scientists make predictions, they sometimes seem wild, almost beyond the realm of possibility. Yet, over the years, many ...

Zachary Yarbrough, an LSU graduate student, explained the features of the Laser Interferometer Gravitational-Wave Observatory's control room to members of the Edward Livingston Historical Association ...

Trump administration proposes closing LIGO Hanford or LIGO Livingston, jeopardizing cutting-edge gravitational wave research near Tri-Cities, Washington.

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.

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.
