The Caltech Submillimeter Observatory (CSO) is a cutting-edge facility for astronomical research and instrumentation development. It is simultaneously one of the world’s premier submillimeter telescopes and one of the easiest to use. It consists of a 10.4-meter diameter Leighton radio dish situated in a compact dome near the summit of Mauna Kea, Hawai’i. The telescope is operated by Caltech under a contract from the National Science Foundation (NSF) and has been operating on a regular basis since 1988. It is open to the astronomical community, with most of the observing time available for non-Caltech observers.

The Caltech Submillimeter Observatory (CSO) is a cutting-edge facility for astronomical research and instrumentation development. It is simultaneously one of the world’s premier submillimeter telescopes and one of the easiest to use. It may also have the distinction of being the world’s only professional observatory without an operator. The astronomer is given full control of the telescope during observing. The CSO is located on “submillimeter ridge” near the summit of Mauna Kea, Hawai’i. The telescope is operated by Caltech under a contract from the National Science Foundation (NSF) and has been operating on a regular basis since 1988.
