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. Since the ...

The Trump administration wants to close one of the nation’s two cutting-edge observatories — one of them in the Tri-Cities — that made scientific history and launched a new way to study the universe.

After a prolonged absence from the gravitational-wave-detection scene, the massive LIGO project is back up and running. The Laser Interferometer Gravitational-Wave Observatory (LIGO) works in ...

The first observation of neutron stars colliding happened in August 2017 and was notable for showing that both gravitational waves and light were generated by the event. The more recent observation of ...

Trump budget proposal seeks to close one of two U.S. LIGO observatories by 2026. LIGO facilities detected first gravitational waves and advanced multi-messenger astronomy. Proposed closure risks ...
