This means LIGO would be able to detect gravitational waves even from merging neutron stars that are about 4 megaparsecs (roughly 13 million light-years) farther away than before.

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 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 ...

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

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

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 at MIT, Caltech, and elsewhere report a significant advance in quantum squeezing, which allows them to measure undulations in space-time across the entire range of gravitational ...

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 first became world-famous in Sept. 2015, when it detected gravitational waves from merging black holes for the first time. These ripples had traveled for around 1.4 billion years, squashing ...

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.

Could LIGO find alien spacecraft accelerating to near light speed? The gravitational wave detector LIGO has made hugely important discoveries. But what else might be hiding in the ripples’ of ...
