Brian Cox and Dara O Briain return for another celebration of space and astronomy. This series they talk to British astronaut Tim Peake as he orbits 250 miles above the Earth. Tim reveals how he is settling into life on the International Space Station just one month after his launch into space. Brian and Dara also attempt to make a garden shed fly, as they explore what keeps the ISS in space.

Roving reporter Liz Bonnin reports live from the European Astronaut Centre in Cologne, where she finds out whether comedian John Bishop has the 'right stuff'. A lifelong astronomy fan, John will be following astronaut Tim Peake's training programme over three nights, starting with a live, simulated space-walk - underwater.

Brian and Dara are joined in the studio by NASA scientist Carly Howett to enjoy some spectacular new views from the surface of Pluto, as well as exploring some of the biggest planets and stars in the universe. They will also be asking for your help to find new pulsars - spinning stars that are heavier than the Sun, yet smaller than Manchester. Meanwhile, Professor Lucie Green will be on hand to guide you around the night sky and to show you how to photograph the International Space Station.
