The Hanford Site hosts the LIGO Hanford Observatory, which detects gravitational waves.
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 .. physics. physics. Two large observatories were built in the United States with the aim of detecting gravitational waves by laser interferometry .. laser. laser. interferometry. interferometry. The initial LIGO observatories were funded by the National Science Foundation -LRB- NSF -RRB- and were conceived , built , and are operated by Caltech and MIT .. National Science Foundation. National Science Foundation. Caltech. Caltech. MIT. MIT. They collected data from 2002 to 2010 but no gravitational waves were detected .. The Advanced LIGO Project to enhance the original LIGO detectors began in 2008 and continues to be supported by the NSF , with important contributions from the UK Science and Technology Facilities Council , the Max Planck Society of Germany , and the Australian Research Council .. UK Science and Technology Facilities Council. Science and Technology Facilities Council. Max Planck Society. Max Planck Society. Australian Research Council. Australian Research Council. The improved detectors began operation in 2015 .. The detection of gravitational waves was reported in 2016 by the LIGO Scientific Collaboration -LRB- LSC -RRB- and the Virgo Collaboration with the international participation of scientists from several universities and research institutions .. LIGO Scientific Collaboration. LIGO Scientific Collaboration. Virgo Collaboration. Virgo interferometer. Scientists involved in the project and the analysis of the data for gravitational-wave astronomy are organised by the LSC , which includes more than 1000 scientists worldwide , as well as 440,000 active Einstein@Home users .. gravitational-wave astronomy. gravitational-wave astronomy. Einstein@Home. Einstein@Home. LIGO is the largest and most ambitious project ever funded by the NSF .
