The Australia Telescope, also known as the Australia Telescope Compact Array is a radio telescope at the Paul Wild Observatory, 25 kilometres west of the town of Narrabri, Australia. The Parkes 64 metre radio telescope in New South Wales, Australia (the bigger of the two shown) In contrast to an ordinary telescope, which produces visible light images, a radio telescope sees radio waves emitted by radio sources, typically by means of a large parabolic (dish) antenna, or arrays of... A number of major astronomical facilities are located at the Paul Wild Observatory near Narrabri, Australia, including: The Australia Telescope Compact Array radio telescope The Narrabri Stellar Intensity Interferometer (now decommissioned) The Sydney University Stellar Interferometer (see http://www. ... Narrabri is a town of approximately 8000 persons and a Local Government Area in north-central New South Wales. ...

The telescope is an array of six identical dishes, which commonly operate in aperture synthesis mode to produce radio images. Aperture synthesis is a type of interferometry that mixes signals from a collection instruments to produce measurements having the same angular resolution as an instrument the size of the entire collection. ...

The compact array is a part of the Australia Telescope National Facility network of radio telescopes. The array is frequently operated together with the 64m dish at the Parkes Observatory and a single dish at Mopra, to form a very long baseline interferometry array. The Australia Telescope National Facility (ATNF) is a division of the Commonwealth Scientific and Industrial Research Organisation (CSIRO) of Australia, and is a government-operated research facility dedicated to radio astronomy. ... The Parkes Observatory in New South Wales, Australia The big dish The Parkes Observatory is a radio telescope observatory, 20 kilometres north of the town of Parkes, New South Wales, Australia. ... Very Long Baseline Interferometry (VLBI) is a type of interferometry in which the data received at each antenna in the array is paired with timing information, usually from a local atomic clock, and then stored for later analysis on magnetic tape or hard disk. ...
