Brian Cox goes down under and stares up at southern skies; Rio Ferdinand explores grief and emotional struggles. Plus: Jim Al-Khalili investigates gravity

For this new series, Brian Cox and Dara O Briain trade Jodrell Bank for its equivalent on the other side of the world: the Siding Spring Observatory, situated on a mountaintop in New South Wales. As the dawn approaches, Brian and Dara are joined by Liz Bonnin to discuss what they spotted overnight, along with input from outback astronomer Greg Quicke, who is acting as their guide to the sprawling southern skies.
