Welcome to LIGO Livingston

• July 19, 2024

LIGO Livingston is located in Livingston Louisiana, in a vast, humid, loblolly pine forest. Home to one of LIGO's two gravitational wave detectors, our facility operates in tandem with LIGO Hanford to listen for the faint whispers of gravitational waves from the most energetic events in the universe. LIGO Livingston is also home to LIGO's Science Education Center, which hosts schools, teacher workshops, tours and monthly Science Saturdays - where the public is invited to explore the science and engineering that underpin our quest to study the universe via gravitational waves.
