Video: The return of BBC Two's Stargazing Live It's that time of the year, when Professor Brian Cox and Dara O Briain brighten up the dark nights trying to convince us that the heavens are the most fascinating thing on Earth. For the next three evenings they broadcast live from the Jodrell Bank Observatory, calling on a galaxy of astronomy experts to explore (and explain) the wonders of the universe. There's an added poignancy this year following the death of TV's greatest amateur astronomer Sir Patrick Moore. Tomorrow's show will probe deep into the history of the universe with the help of NASA's newest telescope, while Wednesday's will be devoted largely to asteroids and comets. But tonight the search for life on Mars is the focus, with viewers invited to help explore an uncharted area of the planet from the comfort of their sofas, while Liz Bonnin will report from NASA's Jet Propulsion Lab about the latest Mars rover (see clip above). In a slightly different orbit, reporter Mark Thompson will be showing the best way to view Jupiter's moons and recreating one of pioneering astronomer William Herschel's 18th-century telescopes in Derby. In Stargazing Live: Back to Earth, which follows, the audience gets a chance to chip in and discuss the show's findings. 'Stargazing Live' begins tonight on BBC Two at 8.00pm
