The Laser Interferometer Gravitational-Wave Observatory (LIGO), a collaboration between Caltech and MIT, is a facility dedicated to the detection and measurement of gravitational waves. Two installations, one on the east coast and one on the west, operate as a single simultaneous unit to trace the effects of "ripples in the fabric of space and time produced by violent events in the distant universe." From the homepage check out LIGO News, a blog that reports the latest from the laboratory. The Resources for Press & Media section leads visitors to LIGO photos, LIGO chronology, and a LIGO fact sheet, where Frequently Asked Questions are answered. LIGO is one of the great physics labs of our time, and this web site provides insight into the groundbreaking work happening there every day.
