    Welcome to LIGO Livingston

    • October 9, 2020

    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.

    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.

Science Saturdays cancelled

News Release • January 7, 2021

LIGO Livingston Observatory is canceling its March 2020 through February 2021 Science Saturdays, as well as all other public events in order to reduce risks posed by COVID-19. This decision comes from following Louisiana and CDC guidelines limiting events involving large gatherings of people, especially in communal/small spaces. We apologize for any inconvenience this may cause, and we hope to resume our regular tour schedule in the future.
