What does a Martian look like?

Fictional aliens come in all shapes and sizes - but what would a creature from another planet really look like? Would we even recognise one if we met it? In a new book published this month, science fiction writers Jack Cohen and Ian Stewart set out to find the answers.
The first thing to get straight when thinking about life on other planets, according to Jack Cohen, is that it will almost certainly not be humanoid.
"We've got to get away from all those comfortable ideas that aliens will be just like us, except for a few minor differences that don't challenge our imagination."
"They might look exactly like people. Or cats. Or houseflies. Or they could be invisible, or lurking just outside our space time continuum."
Considering the amount of planets in the universe, chances are high that extra-terrestrial life does exist. The only question is if they have the technology to cross the enormous distances (and if they want to visit, of course).
