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 latest operating run of the LIGO Hanford observatory near Richland hit the jackpot. The network of its twin gravitational wave observatory in Louisiana and a detector in Italy picked up ripples in ...

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 ...

Just shy of a century after Einstein penned his infamous paper on general relativity scientists finally confirmed a cornerstone of his predictions in 2015 — gravitational waves, little curvatures of ...

LIGO Hanford, along with other gravitational wave observatories, is reporting finding a “mystery object” in space. In the past they’ve detected evidence of black holes, created when the most massive ...

Scientists are certain they have detected the rare collisions of a black hole and a neutron star for the first time with the help of the LIGO observatory at Hanford in Eastern Washington. The violent ...

It took less than a second for the space observatory hidden in Louisiana woods to detect the most massive black hole ever observed. Only one tenth of a second to be exact. That's how long it took for ...

When the most massive stars reach the ends of their lives, they blow up in spectacular supernova explosions, which seed the ...

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 ...
