Come on a cosmic journey of scientific discovery with one of the youngest female astrophysicists on the planet, Jo Dunkley. From the basics - like why the earth orbits the Sun - to astonishing facts about star catalogues and superclusters, this brilliant communicator teaches us all about our astonishing galaxy, hosted by multi-award-winning STEM journalist and Wiradjuri woman, Rae Johnston.

Along the way, we encounter some extraordinary, little-known women who defied the restrictions placed on them because of their gender, and whose pioneering research laid the foundations that Professor Dunkley has built on.
