LIGO and Virgo make first detection of gravitational waves produced by colliding neutron stars
Press release • October 16, 2017
For the first time, scientists have directly detected gravitational waves — ripples in space and time — in addition to light from the spectacular collision of two neutron stars. This marks the first time that a cosmic event has been viewed in both gravitational waves and light.
Gravitational waves from a binary black hole merger observed by LIGO and Virgo
News Release • September 27, 2017
The LIGO Scientific Collaboration and the Virgo collaboration report the first joint detection of gravitational waves with both the LIGO and Virgo detectors. This is the fourth announced detection of a binary black hole system and the first significant gravitational-wave signal recorded by the Virgo detector, and highlights the scientific potential of a three-detector network of gravitational-wave detectors.
LIGO Detects Gravitational Waves
Detection Portal • February 11, 2016
On September 14, 2015 at 5:51 a.m. Eastern Daylight Time (09:51 UTC), the twin Laser Interferometer Gravitational-wave Observatory (LIGO) detectors, located in Livingston, Louisiana, and Hanford, Washington, USA both measured ripples in the fabric of spacetime – gravitational waves – arriving at the Earth from a cataclysmic event in the distant universe. The new Advanced LIGO detectors had just been brought into operation for their first observing run when the very clear and strong signal was captured.
LIGO Designated APS Historic Site
News Release • June 15, 2018
On June 20th, LIGO's two detector sites will be designated historic sites by the American Physical Society. The two observatories - one in Livingston, Louisiana and one in Hanford, Washington - will receive plaques recognizing the historic nature of the first direct detection of gravitational waves.
