Anglo-Australian Telescope (AAT)
It came into operation in 1974 and, among many others tasks, is used, in conjunction with a high-resolution échelle spectrometer, to carry out the Anglo-Australian Planet Search – an ongoing survey that began in 1998 to search for extrasolar planets around 240 relatively nearby stars in the southern hemisphere. The AAT was also used in the WiggleZ program, which ran from 2006 to 2011, and also employed NASA's GALEX space telescope to survey the distribution of about 200,000 galaxies out to distances of 8 billion light-years.
