The LIGO gravitational wave observatory in the United States is so sensitive to vibrations it can detect the tiny ripples in space-time called gravitational waves. These waves are caused by colliding ...

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.

The best place to observe the stars is among them, which is why Hubble and the James Webb Space Telescope have been deployed outside Earth's murky atmosphere. At least, that's the case when you're ...

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 ...

This is an aerial view of the Laser Interferometer Gravitational-wave Observatory (LIGO) detector in Livingston, Louisiana. LIGO has two detectors: one in Livingston and the other in Hanford, ...

RIVERSIDE, Calif. -- Finding patterns and reducing noise in large, complex datasets generated by the gravitational wave-detecting LIGO facility just got easier, thanks to the work of scientists at the ...

New mirror coatings will increase the volume of space LIGO can probe in its next run. Since LIGO's groundbreaking detection, in 2015, of gravitational waves produced by a pair of colliding black holes ...

The Indian government has granted the final approvals necessary for construction to begin on LIGO-India, a nearly identical version of the twin LIGO (Laser Interferometer Gravitational-Wave ...
