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.

The LIGO detector in Hanford, Wash., uses lasers to measure the minuscule stretching of space caused by a gravitational wave. LIGO Laboratory LIGO is comprised of two separate observatories ...

But since then, LIGO, and its partner gravitational wave detector Virgo, have detected signals from far more merging black hole pairs, colliding neutron stars, and mixed mergers between the two.

Astronomers have unearthed fresh evidence supporting the existence of intermediate-mass black holes, a category between ...

The Laser Interferometer Gravitational-Wave Observatory (LIGO), which has two massive detectors in Hanford, Washington, and Livingston, Louisiana, is now restarting with improved sensitivity after ...

In the world of black holes, there are generally three size categories: stellar-mass black holes (about five to 50 times the ...

In 2015, a piece of equipment at an observatory in the US moved one quintillionth (10-18) of a meter. This tiny movement was ...

Jackie explains that a laser inside the tubes is split, bounces off mirrors, and goes straight back to sensors at the center ...

While current gravitational wave detectors — such as Laser Interferometer Gravitational-wave Observatory (LIGO) and its sister site Virgo — have proven very successful, a new study argues ...

"Black holes are the ultimate cosmic fossils," Jani said. "The masses of black holes reported in this new analysis have remained highly speculative in astronomy. This new population of black holes ...
