|Welcome to LIGO Hanford Observatory, located in the Columbia Basin region of southeastern Washington. LIGO, the Laser Interferometer Gravitational-wave Observatory, seeks to detect gravitational waves -- ripples in the fabric of spacetime. First predicted by Einstein in his theory of general relativity, gravitational waves are produced by exotic events involving black holes, neutron stars and objects perhaps not yet discovered. Use our links to explore LIGO science, public outreach and educational resources.

| LIGO's holiday tour will occur on Friday, December 27 from 3:00 to 5:00 PM. No, those aren't reindeer in the photo -- we were very surprised to see an elk herd at our doorstep early in December. We can't promise that large animals will present themselves during our tour, but we can guarantee a great look at LIGO's facility and an update on the progress of Advanced LIGO. Will you be hosting guests over the holidays? Keep our December 27 tour in mind. All ages are welcome (although tours work best for middle school ages and above). Admission is free and LIGO's facilities are wheelchair accessible.

|LIGO Magazine, Issue Three Read issue three (left) to learn of the challenges and successes of a multi-continent multi-decade research effort in squeezed light. Squeezing tests in the GEO600 detector and in LIGO Hanford's H1 detector have shown the promise of this method for boosting the sensitivity of gravitational wave interferometers. LIGO Magazine comes to you from the international LIGO Scientific Collaboration and delivers twice-yearly news of the worldwide effort to detect gravitational waves along with interesting features from related areas of astrophysics.|
|What do you want to know about LIGO? LIGO Hanford's list of Frequently Asked Questions (FAQ) now resides on our Web site. Surf our FAQ for responses to often-asked questions that cover various aspects of LIGO detector operations, data analysis, astronomy/astrophysics and working life at the Observatory. LIGO Hanford thanks students from Liberty High School and Sammamish High School for sending in the questions that started the LHO FAQ!|
|View recent Advanced LIGO progress at LIGO Hanford by sampling our updated photo galleries. LHO now has completed the first two tests of Advanced LIGO seismic and suspension subsystems and optical controls, exercising Advanced LIGO hardware between the main laser and one of the detector end stations. The next test, incorporating the other long arm and end station, will begin in November 2013. Commissioning of the full advanced H1 and L1 interferometers will begin in 2014 as the LIGO team moves toward a late 2014 return to detector operations. View the photo galleries|
