The Southern African Large Telescope (SALT)
Dartmouth's major ground-based facility is the Southern African Large Telescope (SALT) in Sutherland, South Africa which is used remotely via queue scheduling. SALT is the largest single optical telescope in the southern hemisphere and among the largest in the world. It has a hexagonal primary mirror array 11 metres across, comprising 91 individual 1m hexagonal mirrors.
MDM Astronomical Observatory
MDM is operated jointly by Dartmouth, the University of Michigan, Ohio State University, Ohio University, and Columbia University. MDM has 2.4-m and 1.3-m telescopes and a suite of state-of-the-art optical and infrared instruments.
For teaching purposes the Department has one 12 inch and one 14 inch Meade. These telescopes are located on the roof of Wilder Laboratory.
In addition to SALT and MDM, Dartmouth astronomers, faculty, and students make use of many more of the world's leading space- and ground-based observational facilities, including the Hubble, Spitzer, and Herschel space observatories, Chandra, XMM-Newton, NuSTAR, and Suzaku X-ray satellites, the Wide-Field Infrared Survey Explorer, W.M. Keck Observatory, MMT Observatory, and the Sloan Digital Sky Survey, as well as being involved in the planning of upcoming and proposed missions including WFXT. - See more at: http://physics.dartmouth.edu/research/astrophysics#sthash.MkV4NxCE.dpuf
