CSIRO's Australia Telescope Compact Array is a world leading instrument for radio astronomy and deep views into the universe.
Just 25 kilometres west of Narrabri on the Yarrie Lake Road (which is fully sealed), in rural New South Wales, the array consists of six 22 metre dish antennas, weighing 270 tonnes each, located on a six kilometre road and railway track to simulate one very large antenna!
Open seven days a week, admission is free. Visitors can enjoy panoramic views of the antennas and wander through indoor and outdoor astronomy exhibits. A theatrette features free films on space and astronomy.
Visits by the general public are always welcome.
