Fred Lawrence Whipple Observatory
Encyclopedia
The Fred Lawrence Whipple Observatory is an astronomical
observatory
owned and operated by the Smithsonian Astrophysical Observatory
(SAO) and is their largest field installation outside of their main site in Cambridge
, MA. It is located near Amado, Arizona
on the slopes of Mount Hopkins
.
Research activities include imaging and spectroscopy of extragalactic, stellar, and planetary bodies, as well as gamma-ray
and cosmic-ray
astronomy.
Formerly known as "The Mount Hopkins Observatory," the observatory was renamed in late 1981 in honor of Fred Lawrence Whipple
, noted planetary expert, space science pioneer, and director emeritus of SAO, under whose leadership the Arizona facility was established.
, which is jointly run by SAO and the University of Arizona
and houses a 6.5-meter telescope. The observatory also has 1.5- and 1.2-meter reflectors and a second 1.3-meter reflector named PAIRITEL (Peters Automated IR Imaging Telescope, ex-2MASS ). Also on site is the HATNet (Hungarian-made Automated Telescope) network and the new MEarth project.
The observatory is known for its pioneering work in ground-based gamma-ray astronomy through the development of the Imaging Atmospheric Cherenkov
Technique (IACT) with the Whipple 10-meter Telescope during the early 1980s. The Whipple 10-meter is currently preparing to be decommissioned after forty years of service.
In April 2007, VERITAS
(a system of 4 IACT telescopes with 12-meter reflectors) started full operations at the FLWO basecamp. Subsequently, in September 2009, after a 4 month effort, one of the telescopes was moved to a new position, making the array symmetric and increasing its sensitivity.
