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. [1]
The LIGO Exploration Center or LExC (sounds like “Lexi”) is a Washington state-funded outreach center at the Richland observatory, aimed at K-12 students and the general public.
The center was established on October 13, 2023, to combine the various groups working on the LIGO Scientific project. [1] [2]The LIGO research at Syracuse began with theoretical contributions from Peter Bergmann, Joshua N. Goldberg, and Roger Penrose, [1] and Syracuse had a comparatively large number of collaborators on the team that made the first observation of gravitational waves in 2015.
Northern arm of the LIGO Hanford Gravitational-wave observatory. Direct observation of gravitational waves was not possible for many decades following their prediction, due to the minuscule effect that would need to be detected and separated from the background of vibrations present everywhere on Earth.
The LIGO Hanford Observatory near Richland is expected to detect 60% more cataclysmic cosmic events — like colliding neutron stars and black holes — thanks to a quantum limit breakthrough ...
Tours of the LIGO Hanford observatory are being planned the same day with tickets required. Ticket signup ends Oct. 13 and all tickets for tours of two of the four tour times are already gone.
Currently, the most sensitive ground-based laser interferometer is LIGO – the Laser Interferometer Gravitational Wave Observatory. LIGO is famous as the site of the first confirmed detections of gravitational waves in 2015. LIGO has two detectors: one in Livingston, Louisiana; the other at the Hanford site in Richland, Washington.
The LIGO Hanford Control Room. As a young area of research, gravitational-wave astronomy is still in development; however, there is consensus within the astrophysics community that this field will evolve to become an established component of 21st century multi-messenger astronomy. [50]
