Australia's leading observatories for radio astronomy are used by astronomers from around the world, 24 hours a day, every day, to learn about our Universe.
The Australia Telescope Compact Array (ATCA), at the Paul Wild Observatory, is an array of six 22-m antennas used for radio astronomy. It is located about 25 km west of the town of Narrabri in rural NSW (about 500 km north-west of Sydney).
Made up of six identical antennas, the Australia Telescope Compact Array is used by astronomers to study the structure and evolution of our Universe.
A visit to our Australia Telescope Compact Array is a highlight of any trip to the north-west region of New South Wales.
Parkes Observatory, just outside the central-west NSW town of Parkes, hosts the 64-metre Parkes radio telescope, one of the telescopes comprising CSIRO’s Australia Telescope National Facility.
Our Parkes radio telescope has been in operation for more than 50 years. Thanks to regular upgrades, it continues to be at the forefront of discovery.
Whether you're travelling with your family, school or a tourist group, our Parkes radio telescope is a great place to visit.
