You could help scientists look through thousands of images of the moon's surface in a bid to find proof of alien existence.
Physicists Paul Davies and Robert Wagner have proposed an online search for alien evidence on the surface of the moon by studying in detail thousands of photographs taken by NASA's Lunar Reconnaissance Orbiter.
They say: "If it costs little to scan data for signs of intelligent manipulation, little is lost in doing so, even though the probability of detecting alien technology at work may be exceedingly low.
Volunteers are being called in to look for any sign at all that aliens might have been to the lunar surface.
The physicists, who work at Arizona State University, believe there may be signs of extra terrestrial life in the form of messages, scientific instruments, waste or evidence of mining that could be spotted by human telescopes and orbiting spacecraft. More info.
