Stargazing Live

Brian Cox and Dara O Briain return for their third night celebrating space and astronomy, with more updates from British astronaut Tim Peake. This time they explore what keeps Tim and his International Space Station crew-mates safe in the hazardous environment of space. Brian and Dara also welcome a very special guest to take the gravity challenge - and find out what it would feel like to walk on Mars and the Moon. Roving reporter Liz Bonnin once more reports live from the European Astronaut Centre in Cologne, where she tests whether comedian John Bishop has the 'right stuff'. A lifelong astronomy fan, John will be strapped into a giant centrifuge machine to experience how future astronauts will simulate gravity during missions into deep space. Brian and Dara are joined in the studio by Dame Jocelyn Bell-Burnell, to hear how she discovered the first pulsar star - giving astronomers all over the world one of their most precious tools for studying the universe. They also find out whether Stargazing viewers have discovered any new pulsars in their three-night search, training Jodrell's famous telescope onto them to reveal exactly what has been discovered, and how much that means to astronomers.

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.

With the solar eclipse just hours away, Dara O Briain, Brian Cox and special guest experts are back at Jodrell Bank to answer viewers' questions. Apollo 11 astronaut Buzz Aldrin is on hand to explain why he believes humans must walk on the surface of Mars.

Brian Cox and Dara O Briain host their final night of stargazing from Jodrell Bank Observatory where, following the day's extraordinary events, they have exclusive images from the solar eclipse. Brian also reveals the latest discoveries and solar secrets of our nearest star, whilst Liz Bonnin discovers how a new generation of missions to the sun will fly closer than ever before.

Brian Cox and Dara O Briain are back at Jodrell Bank Observatory, building up to one of biggest astronomical events of the decade - a solar eclipse. They are joined by legendary Apollo astronaut Buzz Aldrin, who tells them why he believes we must look beyond the moon for mankind's next giant leap.

Brian Cox and Dara O Briain host the second night of their three-day stargazing extravaganza from Jodrell Bank Observatory, where they are joined by two generations of astronauts. Walt Cunningham was one of the first ever crew to fly an Apollo spacecraft into orbit, while Commander Chris Hadfield recently returned from months aboard the International Space Station.

Dara and Brian's journey through the night sky continues with a look into the distant past, explaining how it is possible to chart the history of the universe by looking million of light years out into the depths of space. Meanwhile, Mark Thompson reveals what can be learned from the colours of the stars. At NASA, Liz Bonnin meets the team building the largest space telescope in the world, an instrument that's 100 times more powerful than the Hubble.

Dara and Brian's journey through the night sky continues with a look at black holes, the most mysterious and destructive objects in the whole universe. Liz Bonnin finds out how our galaxy the Milky Way was formed and Mark Thompson investigates the problems that are caused by light pollution.

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.
