The Birth of Radio Astronomy Tour

We will start at Rodney Reserve, Dover Heights. This is the site of the first discovery of solar activity using an interferometry technique. In 1946 Ruby Payne Scott used the cliff interferometer to discover that radio waves from the sun were coming from sunspots. Ruby Payne-Scott was the first woman in Australia working in radio astronomy. The Dover Heights site was used by scientists from the CSIRO for experimental radar work. The four discoveries made here at Dover Heights changed our understanding of the Universe.
