The Anglo-Australian Telescope (AAT), which was opened in 1974 by HRH Prince Charles, is operated by ANU.

The AAT is an equatorially-mounted telescope and, with a 3.9m-diameter mirror, is the largest optical telescope in Australia.  It is equipped with a robotic spectrograph that can simultaneously observe hundreds of galaxies and stars.  It has also been used to carry out several important southern sky surveys, and plays an important role in the search for planets around other stars.
