Anglo-Australian Telescope (AAT)
A 3.9-meter (153-inch) reflecting telescope
located at the Anglo-Australian Observatory.
It came into operation in 1974 and, among many others tasks, was used in
the Anglo-Australian Planet Search
and WiggleZ. The latter ran from 2006 to 2011, and used both the AAT and
NASA's GALEX space telescope to survey the
distribution of about 200,000 galaxies out to distances of 8 billion light-years.
