Its first use was to set the State's latitude & longitude, as well as the State's standard time; from 1901 it was then used to create a standard star reference frame of 420 stars for the Perth Astrographic Catalogue covering the declination zone -32°S to -40°S. The Perth Observatory in Western Australia provided a crucial southern

The opening of the Australia Telescope in September 1988. Photo Nick Lomb The opening of the Australia Telescope in 1988 was very important to the further development in radio astronomy in Australia. The core of the radio telescope is the Australia Telescope Compact Array (ATCA) at Narrabri, NSW. Four of ATCA’s six 22-m dishes are shown in the image above taken at the opening of the telescope by then Prime Minister Bob Hawke. To find out more about how Astronomy changed in Au
