  1. LIGO

    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 with the aim of detecting gravitational waves by laser interferometry. These observatories use mirrors spaced four kilometers apart which are capable of detecting a change of less than one ten-thousandth the charge diameter of a proton.The initial LIGO observatories were funded by the United States National Science Foundation (NSF) and were conceived, built and are operated by Caltech and 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 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 the analysis of the data for gravitational-wave astronomy are organized by the LSC, which includes more than 1000 scientists worldwide, as well as 440,000 active Einstein@Home users as of December 2016.LIGO 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".Observations are made in "runs". As of January 2022, LIGO has made three runs (with one of the runs divided into two "subruns"), and made 90 detections of gravitational waves. Maintenance and upgrades of the detectors are made between runs. The first run, O1, which ran from 12 September 2015 to 19 January 2016, made the first three detections, all black hole mergers. The second run, O2, which ran from 30 November 2016 to 25 August 2017, made eight detections, seven black hole mergers, and the first neutron star merger. The third run, O3, began on 1 April 2019; it was divided into O3a, from 1 April to 30 September 2019, and O3b, from 1 November 2019 until it was suspended on 27 March 2020 due to COVID-19. The O3 run made the first detection of a merger of a neutron star with a black hole.The gravitational wave observatories LIGO, Virgo, and KAGRA are coordinating to continue observations after the COVID-caused stop and as of September 2022, plan to start the O4 Observing run together in March 2023 (launch of LIGO Livingston's interferometer planned for February 2023 ). LIGO projects a sensitivity goal of 160–190 Mpc for binary neutron star mergers (sensitivities: Virgo 80–115 Mpc, KAGRA greater than 1 Mpc).


  1. LIGO

    LIGO, which stands for the Laser Interferometer Gravitational-Wave Observatory, is a large-scale physics experiment aiming to directly detect gravitational waves. Cofounded in 1992 by Kip Thorne and Ronald Drever of Caltech and Rainer Weiss of MIT, LIGO is a joint project between scientists at MIT, Caltech, and many other colleges and universities. It is sponsored by the National Science Foundation. At the cost of $365 million, it is the largest and most ambitious project ever funded by the NSF. Observations at LIGO began in 2002 and ended in 2010; no unambiguous detections of gravitational waves have been reported. The original detectors were disassembled and are currently being replaced by improved versions known as "advanced LIGO", scheduled to be operational by 2014. The international LIGO Scientific Collaboration is a growing group of researchers, over 800 individuals at roughly 50 institutions, working to analyze the data from LIGO and other detectors, and working toward more sensitive future detectors. The current spokesperson for the LIGO Scientific Collaboration, re-elected in March 2013, is Louisiana State University Professor of Physics and Astronomy, Gabriela González.

Examples of ligo in a Sentence

  1. Todd Thompson:

    Immediately, everyone was like' wow,' because it was such a spectacular thing, not only because it proved that LIGO worked, but because the masses were huge. Black holes that size are a big deal -- we hadn't seen them before.

    I realy think you need to update this article. Gravity waves were first detected at the Livingston, Louisiana LIGO facility in September 2015 ,and 7/1,000,000 of a second later, at the Washington state LIGO facility. Being first at detecting gravity waves in Livingston Parish has prompted the locals to brag that Livingston is First in Gravity Wave Detection, and some are organizing a "Gravity Wave Festival" in which there will be much drinking, music, and acting stupid, which is a tradition in Louisiana dating back at least 200 years.. However, prior to detecting gravity waves, most residents of Livingston Parish did not even know of the existance of LIGO.
