Review & Frequenly Asked Questions:

The LIGO Hanford Observatory is the world's largest gravitational wave observatory featuring two gigantic laser interferometers that detect and understand the origins of gravitational waves through the exploitation of light and space.

The interferometers are located in Hanford and Livingston, Louisiana, while two primary research centers can be found in Pasadena, California, and MIT in Cambridge, Massachusetts, which are part of the Observatory.

LIGO Hanford offers free public tours of the observatory on the second Saturday of each month, which includes a public talk by a LIGO staff member.
