The LIGO Hanford Observatory near Richland is expected to detect 60% more cataclysmic cosmic events — like colliding neutron stars and black holes — thanks to a quantum limit breakthrough.

The LIGO Hanford observatory was set to officially start another operating run Wednesday, but it may have already made another significant detection of a violent event long ago in outer space.

To measure it, LIGO was created. The observatory, operated by the California Institute of Technology, consists of two stations -- one in Livingston, La., and the other at Hanford, near Richland.

first as a graduate student at MIT and then as a scientist at the LIGO Hanford Observatory beginning in 2013. "Squeezing was first thought of in the late 1970s, but it took decades to get it right." ...

On May 24, scientists at the Laser Interferometer Gravitational-Wave Observatory (LIGO) began an 18-month campaign to detect the most distant collisions between black holes and neutron stars ever ...

The LIGO Hanford observatory and Columbia Basin College’s Planetarium plan a viewing event and activities on the LIGO campus near Richland. If skies are too cloudy to see the eclipse ...

We asked Elenna Capote, LIGO Scientific Collaboration fellow working at the LIGO Hanford Observatory some questions about gravitational waves. All gravitational systems can create gravitational waves.
