When Carmen and Zane escape from the ship, you can see many bodies floating in space. The pressure in space is so infinitesimal that anything that is not very dense will basically explode(one reason for space suits other than the temperature being two degrees above absolute zero.)
Pressure in space is quite infinitesimal, true, but the difference with our own atmospheric pressure (1 bar) is only, well, 1 bar. That's about the same difference in pressure between a lake's surface and the pressure you'd feel at ten meters depth (someone with diving experience please correct me if i'm wrong); fishes don't explode if you catch them, and neither would we in space.
In recent years, deep sea divers found that there are fish that live in the deepest known waters, in amazingly high pressure. When these fish were brought to the surface, they exploded because of the sudden lack of pressure. Therefore, its fairly safe to assume that humans would react the same way to an extreme pressure change.
Boiling = when the pressure exerted by the liquid is greater than the pressure exerted on it. SO in space the pressure of our blood is higher than the pressure of space so our blood would boil and our bodies would explode.
(this shouldn't be that hard to figure out, i learned it in 9th grade physical science :P )
That humans explode in space is a myth. The air rushes out of your lungs, true, but this will only cause damage if you try to hold it. Your blood does NOT boil, your blood vessels are too well insulated. In fact you could be ejected in to space, become unconscious through lack of oxygen, be recovered five minutes later and be fine.
Lol! What are you talking about!? You must be like two years old. The only change noticable to the bodys from that distance would be that theirs skin as fragmented and borken off. (Temperature difference etc.) Your head won't explode, certainly not your enire body. Do us a favour and never add a slip-up cause you obviously don't know a thing...
