The Laser Interferometer Gravitational-Wave Observatory (LIGO) is a large-scale physics experiment and observatory designed to detect cosmic gravitational waves and to develop gravitational-wave observations as an astronomical tool. Two large observatories were built in the United States to see gravitational waves by laser interferometry. These observatories use mirrors spaced four kilometres apart, which can detect a change of less than one ten-thousandth the charge diameter of a proton.
\nThe initial LIGO observatories were funded by the United States National Science Foundation (NSF) and were conceived, built, and operated by Caltech and MIT. They collected data from 2002 to 2010 but detected no gravitational waves.
\nThe Advanced LIGO Project to enhance the original LIGO detectors began in 2008 and continues to be supported by the NSF, with essential contributions from the United Kingdom's Science and Technology Facilities Council, the Max Planck Society of Germany, and the Australian Research Council. The improved detectors began operation in 2015. The detection of gravitational waves was reported in 2016 by the LIGO Scientific Collaboration (LSC) and the Virgo Collaboration with the international participation of scientists from several universities and research institutions. Scientists involved in the project and analysing the data for gravitational-wave astronomy are organised by the LSC, which includes more than 1000 scientists worldwide and 440,000 active users as of December 2016.
\nLIGO is the largest and most ambitious project ever funded by the NSF. In 2017, the Nobel Prize in Physics was awarded to Rainer Weiss, Kip Thorne and Barry C. Barish \"for decisive contributions to the LIGO detector and the observation of gravitational waves\".
