As Stephen Hawking warns about contacting aliens this week, there's still time to get the facts and ask your own extraterrestrial questions in the Natural History Museum's event Is there Anybody Out There? tomorrow at 7pm.
Alien life is almost certain to exist elsewhere in the universe, says Stephen Hawking, one of the world's leading scientists. So, how do scientists search for extraterrestrial life and what do they look for?
Museum meteorite expert Caroline Smith, recently on the BBC's Museum of Life television programme, and astrobiologist Lewis Dartnell from University College London, answer these questions and more.
They will also explore what kind of life forms might be found and what impacts humans may have on this extraterrestrial life.
Caroline Smith will talk about some of the work that goes on behind the scenes at the Museum such as searching for evidence of the existence of life on meteorites.
There will also be video appearances from Margaret Race, from the SETI Institute (Search for Extraterrestrial Intelligence), who works on protecting planets, especially Earth and Mars. And also Zita Martins from Imperial College, who was part the of team who confirmed some of the earliest genetic material to have come from extraterrestrial sources.
This lively debate is part of the Nature Live Nights that take place in the Museum's state-of-the-art Darwin Centre on the last Thursday of every month.
Tickets cost £6 and the event starts at 19.00 on 29 April in the Attenborough Studio, a high-tech audio-visual venue in the Museum's state-of-the-art Darwin Centre.
