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.
Welcome to LIGO Hanford
• August 5, 2015
LIGO Hanford is located in the Columbia Basin region of Central Washington near the Tri-Cities. Home to one of LIGO's two gravitational wave detectors, our facility operates in tandem with LIGO Livingston to listen for the faint whispers of gravitational waves from the most energetic events in the universe.
LIGO Hanford hosts site tours, school field trips and special public events. Use the menus above to see our tour and event schedules and to learn more about the science and engineering that are driving the search for gravitational waves.
New Video: LIGO: A Discovery that Shook the World
News Release • February 22, 2018
The National Science Foundation funded Advanced LIGO Documentary Project released a new video looking at information coming from first multi-messenger detection of colliding neutron stars. On August 8, 2017, LIGO joined forces with Virgo and over 70 astronomical observatories to look at a neutron star merger through gravitational waves and electromagnetic waves (light). This video explores the significance of that event.
