I did some arts on a damn interesting topic. What happens to a body exposed to outer space? It's not what usually happens in sci fi shows. No instant icicles on your nose, no exploding eyeballs, none of that. So what does happen? Follow me down to the pictures. They each illustrate one symptom of space exposure without containment. In reality they'd all be happening at once, to varying degrees.
Prints of all of the below are available here, so you can educate your friends through arts.
Bodies in Space: Boiling Blood
Liquids on the surface of her body will vaporize when exposed to the vacuum of space. Her skin, however, is sufficient to maintain her internal pressure, preventing any blood within her vascular system from boiling.

Bodies in Space: Phase Change
The boiling point of a given liquid is determined by both temperature and pressure. In the absence of atmospheric pressure, any surface liquids on her body (saliva on her tongue, sweat, moisture on her eyes, etc) boils instantly, without the addition of heat. The resulting vapor immediately desublimates into fine crystals.

Bodies in Space: Bruising
Being in a zero-pressure environment will cause swelling of your tissues. Not talking like Total Recall-swelling where your head explodes, but definitely a problem. I'm covering swelling in another picture, though. This one is a result of the swelling: bruises.

Bodies in Space: Cyanosis
Lack of oxygen is your main concern in space. You'd quickly lose consciousness and, as the oxygen supply in your blood runs out, your skin would take on a bluish tint. No joke, I think this is the most important thing I've ever done. The butt of this man. This man's ass.

Bodies in Space: Decompression
This one looks different than the others in the series because it is; this does not happen. Rapid decompression is not enough to rip your skin off, burst your eyes, or make your chest explode. You'd only be going from probably less than 1 atmosphere of pressure to none. Divers undergo pressure changes many many times more severe, albeit slowly, and they're fine. The eyes and chest exploding notions will get their own pictures, too. Until then, though, prints of this one are available here.

Bodies in Space: Sunburn
Another consequence of no protection from radiation in space: you'd get a sunburn very easily. If you're near a star.

Bodies in Space: Radiation
Another thing that happens in space, away from an atmosphere or space ship, is being bombarded by cosmic rays. Many many years after he dies of oxygen deprivation, he will die of cancer.

Bodies in Space: Convection
This is the first of a series called "Bodies in Space." This one illustrates that you don't freeze instantly in space, as if you've been launched out the airlock in Battlestar Galactica. On Earth you lose heat by convecting it into the air around you. In space, though, there is no medium into which you convect heat. Aside from evaporative cooling, the only way to lose heat is to radiate it, which is a far slower process. You'd be dead of something else long before you're cold. Neat!
