Welcome to LIGO Hanford

• January 31, 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.
