New research is shedding light on what researchers call "lite" intermediate-mass black holes, which are smaller, but still ...

This means LIGO would be able to detect gravitational waves even from merging neutron stars that are about 4 megaparsecs ...

Since then, LIGO has detected hundreds of events, including black holes merging and neutron stars colliding. The Hanford site continues to refine its tools and push science forward.

LIGO detected the first-ever confirmed gravitational waves in 2016. Around the same time, its operators were thinking about ways to weed out the quantum disturbances.

LIGO researchers are particularly excited for the new upgrade, however, because this pushes the instrument beyond what is called the "quantum limit" — a first for a gravitational wave detector.

Trump administration proposes closing LIGO Hanford or LIGO Livingston, jeopardizing cutting-edge gravitational wave research near Tri-Cities, Washington.

LIGO Executive Director David Reitze, who oversees both observatories and is based at the California Institute of Technology, said in an email that LIGO is preparing for a 39.6% budget reduction ...

Cities, the Vera C. Rubin and LIGO observatories reveal cosmic secrets, one capturing light and the other listening for the ...

The LIGO detectors in the states were meant to be joined by a third, the Virgo detector, which is located near Pisa, Italy. However, that detector wasn’t ready to go operational, ...

LIGO is a U.S. science megaproject built to detect ripples in spacetime known as gravitational waves. The ones we can detect are largely created by the mergers of black holes and neutron stars.

The twin LIGO gravitational-wave detectors at Hanford, Wash., and Livingston, La., will be joined for O4 by the Virgo detector in Italy as well as the KAGRA observatory in Japan.
