Welcome to LIGO Hanford

• November 16, 2020

LIGO Hanford is located in the Columbia Basin region of Eastern Washington near the Tri-Cities of Richland, Kennewick, and Pasco. Our facility operates in tandem with the LIGO Livingston detector 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 and study of gravitational waves.

LIGO-Virgo Finds Mystery Object in "Mass Gap"

News Release • June 23, 2020

LIGO and Virgo report the observation of a merger involving a black hole of 23 solar masses and a compact object of 2.6 solar masses, detected during LIGO’s and Virgo’s 3rd observing run on August 14, 2019. The merger resulted in a final black hole of about 25 solar masses, located about 800 million light-years from Earth.
