We now know of thousands of planets orbiting other stars. But we know of only planet that hosts life – the Earth. Most scientists think that life elsewhere in the Universe is likely to exist, but so far there is no evidence that extra-terrestrials exist or that they have visited us. However, we can search for signs of life on distant planets and we are even using radio telescopes to look for messages sent to us by extra-terrestrial civilisations. If there is life out there, it probably doesn’t look anything like us. However, if a planet has the capacity to create and sustain life – whether as bacteria or as little green men – it is fairly certain that, like ourselves and other life forms on our own planet, alien life forms have evolved to survive and prosper in that environment. Just for fun, take the tests below to see if you can imagine what kinds of beings might live on the four planetary environments suggested. By clicking and dragging each one, take items from the pool of possible body parts, and attach them to the blank alien’s head, bearing in mind the conditions on each planet, and – build your own alien.
