'Astrobiology’is a new field of science, encompassing research into the origins and limits of life on our own planet, and where life might exist beyond the Earth. There is every expectation that a new space telescope, Kepler, will discover dozens of Earth-like planets orbiting distant stars in just the next three years. Extraterrestrial plants and animals developing on these worlds would be subject to the same laws of physics and engineering constraints as us, but may have followed evolutionary paths unexplored by terrestrial life. So what might alien life really look like? And more importantly for the science of astrobiology, how will this understanding help us to actually detect signs of life on another world?
