Fred Lawrence Whipple Observa
tory Fred Lawrence Whipple Observatory, Amado, Arizona
The major instrument on Mt. Hopkins is the MMT Observatory's 6.5-m-diameter optical telescope (operated jointly by SAO and the University of Arizona). Others include a 10-m gamma-ray airshower Cerenkov telescope as well as the Peters Automated Infrared Imaging Telescope (PAIRITEL), a 1.3-m infrared telescope (formerly the northern 2MASS telescope, now operated by SAO); a 1.2-m imaging optical/infrared telescope; and the 1.5-m Tillinghast spectroscopic telescope. FLWO is also home to HAT, the Hungarian-made Automated Telescope, and MEarth, an array of telescopes used for robotic searches for exoplanets.
Magellan Magellan Telescopes
The Las Campanas Observatory on Cerro Las Campanas in Chile, operates twin 6.5-m optical telescopes for a consortium of institutions, which includes Harvard University, the Carnegie Observatories, MIT, the University of Michigan, and the University of Arizona. Separated by 60 m, the twin telescopes afford fine "natural seeing," from an elevation of 2400 m (8000 feet) in the Chilean Andes and unparalleled access to the Southern Hemisphere skies for astronomers.
MMT Observatory MMT Observatory
The MMT Observatory, a 6.5-meter-diameter optical telescope, is located on the summit of Mt. Hopkins at the Fred Lawrence Whipple Observatory, 30 miles south of Tucson, Arizona. The telescope (operated jointly by SAO and the University of Arizona) includes a suite of advanced wide-field imagers and spectrographs developed and deployed for the MMT by SAO scientists.
VERITAS (Very Energetic Radiation Imaging Telescope Array System) is a new major ground-based gamma-ray observatory with an array of four 12m optical reflectors for gamma-ray astronomy in the GeV - TeV energy range . The telescope design is based on the design of the existing 10m gamma-ray telescope of the Whipple Observatory near Tucson, Arizona. It consists of an array of imaging telescopes that permit the maximum versatility and give the highest sensitivity in the detection of light created by cosmic gamma rays striking the earth's atmosphere.
