Commemorating ATCA construction
The CSIRO Space and Astronomy Radio School is being held this week at the Paul Wild Observatory near Narrabri, the site of the Australia Telescope Compact Array, on Gomeroi Country. Yesterday marked the 39th anniversary of the commencement of construction of the array, which was commemorated with the plaque above. The circle at left represents the Culgoora Radioheliograph, and shows the paths of the transmission lines that brought the signals from the 96 antennas to the central control building. The circle at the right is the back view of an ATCA antenna. In the middle is da Vinci's iconic Vitruvian Man, in two superimposed positions that are inscribed in both a circle and square. Barry Jones, Minister for Science at the time, is also a writer, lawyer, and quiz champion who is on the National Trust's list of Australian Living Treasures.
