I know that space is a vacuum, has no air, and is very, very cold. From what I have seen in movies and TV shows when a space suit is exposed the oxygen will escape like a visible gas and the person would explode.
In the movie Event Horizon one of the characters is blown out of an airlock and one of his comrades tells him to expel all the air in his lungs and to curl up, as he does he seems to be bleeding a lot.
In the movie The Hitchhikers Guide to the Galaxy it says you can hold your breath for a little while before anything happens. Of course all these examples are science fiction so they may or may not be accurate.
I am wondering what would happen if a human body was exposed in space? Would it blow up like so many shows seems to hint? Would the person be frozen to death because of the temperature in space?
NOTE: I ask this as in a fan fiction I am writing, in one scene the main character's daughter is sucked out through a hull breach of the ship before her friend willingly jumps out and holds her as she teleports the two through space to the nearest planet. I want to explain how the adverse effects on an exposed human body are negated, but I can't do that if I don't know what I am negating.
