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 ...

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 ...

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.

LIGO Hanford has a new partner in its search for gravitational waves created by violent events in space. Scientists are expecting the expanded network to lead to more detections of ripples through ...

We need to add “generate ripples in spacetime” to LIGO’s resume. Gravitational waves are ripples that are produced when massive objects warp spacetime. They essentially stretch out space, and ...

LIGO, the Laser Interferometer Gravitational-Wave Observatory, has done it again. Astronomers announced they have detected another gravitational wave tearing through spacetime. The occasion marks the ...

Listening out: an upgrade to the Advanced Laser Interferometer Gravitational-wave Observatory in Hanford, Washington and Livingston, Louisiana could allow the twin detectors to spot gravitational-wave ...

Today, scientists announced that, for the first time in history, gravitational waves have been detected. Gravitational waves are ripples in spacetime throughout the universe. What’s truly remarkable ...
