Laser Interferometer Gravitational-Wave Observatory (LIGO)
The LIGO or the Laser Interferometer Gravitational-Wave Observatory is a big-scale physics experimentation and observatory designed to detect gravitational waves. It aims to develop and use gravitational-wave interpretations as an astronomical instrument. The first such observatories were sponsored by the National Science Foundation or the NSF. They were designed, constructed and functioned by Caltech and the Massachusetts Institute of Technology (MIT). The NSF supports the Advanced LIGO Project which was started in 2008 to augment the original LIGO detectors. This project receives major contributions from the UK Science and Technology Facilities Council, the Australian Research Council and Germany’s Max Planck Society. The Advanced LIGO had enhanced sensitivities and this led to the first detection of gravitational waves. This was done in 2016 in collaboration with LIGO Scientific Collaboration and the Virgo Collaboration, along with scientists from all over the world.
