LIGO - Laser Interferometer Gravitational Wave Observatory Icon

LIGO - Laser Interferometer Gravitational Wave Observatory

The Laser Interferometer Gravitational-Wave Observatory (LIGO) is a facility dedicated to the detection of cosmic gravitational waves and the measurement of these waves for scientific research. It consists of two widely separated installations within the United States, operated in unison as a single observatory. This observatory is available for use by the world scientific community, and is a vital member in a developing global network of gravitational wave observatories.

Funded by the National Science Foundation (NSF), LIGO was designed and constructed by a team of scientists from the California Institute of Technology, the Massachusetts Institute of Technology, and by industrial contractors. Construction of the facilities was completed in 1999. Initial operation of the detectors began in 2001.

LIGO will be used to delve into the fundamental nature of gravity, and as such will throw open an entirely new window onto the universe. Its observations will cross many borders and it will serve as an investigational tool for both physics and astronomy.
