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.

After the country stopped to enjoy the solar eclipse, Dara O Briain and Brian Cox are live at Jodrell Bank for a final 30 minutes of Stargazing to answer viewers' questions with the help of special guests. They also highlight the dates in 2015 when the night sky will provide the greatest show on Earth.

Brian Cox and Dara O Briain are joined by a panel of stellar guests to delve deeper into the universe after a night of Stargazing Live. NASA's Carly Howett discusses 2015's New Horizons mission to Pluto, sharing some of the astonishing discoveries made possible by the images and data still being sent back from the probe. Also in the studio, Professor Chris Lintott explores the strange world of pulsars - spinning stars that are heavier than the Sun, yet smaller than Manchester - and explains how Stargazing viewers can make their own contribution to astronomy by discovering new ones over the next three nights. The panel will be answering viewers' questions, as well as enjoying their photographs of the night sky, including the International Space Station.
