Gravitational Wave Observation Facility "LIGO Louisiana, U.S.A. (November 16, 2012)
LIGO gravitational wave detector optics. Fibre welds for a test mass (mirror) being used at the Laser Interferometer Gravitational-Wave Observatory (LIGO). LIGO compares measurements between two detector sites 3000 kilometres apart in Washington and Louisiana, USA. Each site uses laser interferometers to monitor light beams bounced between mirrors, looking for small changes caused by gravitational waves. LIGO has been operating since 2002, with an advanced upgrade (aLIGO) operating since 2015. This is the X-arm input test mass (ITMX) at the LIGO Livingston site, Louisiana, USA. Photographed on 16 November 2012.
