Molonglo Radio Observatory

Molonglo Radio Observatory

(mŏ-long -gloh) An observatory at Hoskinstown, New South Wales, Australia, run by the University of Sydney. The main instrument is a Mills cross antenna, operational since 1966 although now modified for use as an aperture synthesis instrument (the Molonglo Observatory Synthesis Telescope, MOST) by abandoning the N–S arm and phasing the E–W arm. The arms are about 1.6 km long and consist of a series of 12-meter-wide cylindrical parabolic reflectors. MOST operates at 843 megahertz.
