LIGO’s 20-month observation run 04 will officially start on May 24, and it will later be joined by Virgo and a new Japanese observatory – the Kamioka Gravitational Wave Detector, or KAGRA.

In September 2015, LIGO detected the first gravitational waves ever observed. "I will remember that day for the rest of my life. It was a great moment," Landry said.

The Laser Interferometer Gravitational Wave Observatory (LIGO) has seen over 300 black hole mergers in its short time in operation, and now it’s seen an event so large—and so rare—that it ...

LIGO detects this using a pair of 2.5-mile tunnels that meet at a right angle (see below). A laser is split to travel down each arm, reflect off a mirror, and return to the detector.

LIGO is comprised of two separate observatories, with one located in Hanford, Washington, and the other in Livingston, Louisiana. Each observatory is shaped like a giant L with two, 2.5-mile-long ...

Seven years ago, researchers with the Laser Interferometer Gravitational-Wave Observatory (LIGO) reported the first detection of gravitational waves. Now, the list of gravitational wave candidates ...

LIGO achieved its primary mission in 2015, and the roster of gravitational wave candidates has only grown. The project has even been able to capture the sound of two black holes merging.

Head to Livingston Parish for LIGO's Science Saturday for "Good Vibrations" from 1 p.m. to 5 p.m. The free event allows attendees to experience and experiment with gravitational waves and vibrations.

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 ...

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 ...

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.
