Today we hear about the Parkes radio telescope's role in the search for alien life. Our guide is the irrepressible John Sarkissian, the scientist who's had his eye on The Dish since childhood.
Today we hear about some of the fascinating space research underway at Siding Spring Observatory – and how, despite gruelling hours and endless paperwork, astronomers retain their sense of wonder for the night sky. Shutterstock

Each dot is a galaxy, with around 300,000 radio galaxies observed as part of the GLEAM survey. Natasha Hurley-Walker (Curtin / ICRAR) and the GLEAM Team

What the universe looks like when viewed with radio eyes

To the naked eye the universe we can see on a clear night is dotted with thousands of stars. See through radio eyes, then things look very different.
