AST/RO is a 1.7 meter diameter submillimeter-wave telescope in operation
at Amundsen-Scott South Pole Station since January 1995. Because of its exceptionally
cold and dry atmosphere, the South Pole is the best ground-based observatory site for
astronomical observations at submillimeter wavelengths. The scientific program
is currently focused on spectroscopic observations of atomic and molecular clouds
in the Milky Way and other galaxies. AST/RO invites
observing proposals from the astronomical community.
Since travel to the South Pole is not possible during Austral winter (Feb.-Oct.),
observations on AST/RO are performed by a winterover scientist in residence at
South Pole. The AST/RO facility (shown
in photo, with the main base and an LC-130 aircraft in the background)
is part of CARA: Center for Astrophysical
Research in Antarctica.
