Join Professor Brian Cox and Dara O Briain to wonder at the night sky, with extraordinary images beamed in from telescopes across the globe. Learn how to observe and take pictures over three busy days in the celestial calendar, with a meteor shower, a partial eclipse of the sun and the biggest planet in our solar system, Jupiter, burning bright. Wannabe stargazer Jonathan Ross gets a crash course in planet spotting in his own back garden; while in Hawaii, Liz Bonnin reports from the edge of a volcano to help explain how the Earth was formed.

In the second of three live programmes, Professor Brian Cox and Dara O Briain look at images of the partial eclipse of the sun and investigate how stars are born. Liz Bonnin shows us the sun in a different light - live from Hawaii; while novice star spotter Jonathan Ross discovers the key to observing constellations. Plus astronomer Mark Thompson demonstrates how to find our nearest galaxy, Andromeda.

Jonathan Ross joins Professor Brian Cox and Dara O Briain at Jodrell Bank, home of one of Britain's biggest telescopes, for an hour of live stargazing. The search for extraterrestrial life is the subject of Liz Bonnin's report atop one of the world's highest observatories in Hawaii, Brian chats to the crew of the International Space Station as they orbit the earth at 17,500 miles an hour, and Dara experiences what it is like to be in space.
