Claim: The Hanford Site hosts the LIGO Hanford Observatory, which detects gravitational waves.
Evidence: Besides the cleanup project , Hanford also hosts a commercial nuclear power plant , the Columbia Generating Station , and various centers for scientific research and development , such as the Pacific Northwest National Laboratory and the LIGO Hanford Observatory.
The Laser Interferometer Gravitational-Wave Observatory -LRB- LIGO -RRB- is a large-scale physics experiment and observatory to detect cosmic gravitational waves and to develop gravitational-wave observations as an astronomical tool.
