High Elevation Antarctic Terahertz telescope

Antarctica's newest far-infrared observatory is now in operation at Ridge A, the highest, driest, calmest place on the ice plateau. Established in a collaboration between the University of Arizona (US) and the University of New South Wales (Australia) the exceptional site is dedicated to international astronomical exploration. Building on the legacy of the AST/RO and Herschel observatories, the 60 cm HEAT telescope is constructing spectroscopic maps of the Milky Way in frequency bands from 0.5 to 2 THz (600 to 150 microns wavelength), where the extremely cold and dry conditions of the Antarctic plateau provide an exceptionally clear view. The HEAT telescope is exploring star forming regions, some of the most important yet enigmatic regions in our Galaxy, and aims to solve the mystery of how interstellar clouds are formed and evolve.
