Outer Space Exposure

So you know how in science fiction movies they sometimes talk about people exploding in space? Like if an astronaut gets a hole in their spacesuit, the pressure of the atmosphere will be too intense for the human body to handle, so the person will just explode? I recently saw a part of an old Arnold movie called Total Recall, and when one of the astronauts popped his helmet off, his head exploded. Afterwards I couldn’t stop replaying movie scenes in my head of Luke Skywalker and images of space suits floating in the galaxy and thinking—is that whole concept really legit? As odd as it was googling “people exploding in space”, I got an answer to my question. (By the way, I love how “googling” is an actual word now.) People do die from the outside pressure when exposed to the atmosphere of outer space, however, it is not nearly as tramautic and instantaneous like the way that the film industry portrays it. A great article from NASA explains that your eyes don’t exactly pop out of your head, but “death arises from the response of the free gasses trapped within the tissues.” The pressure causes all of your fluids to turn into vapor, allowing your eyes and mouth to quickly dry out and the moisture in muscles and soft tissues to evaporate. These tissues increase to nearly twice their normal size and your outer skin to turn blue. The sad thing is that during all this, your brain is still functioning and your heart still beating. A person has about a minute and a half to save themselves if they find administered oxygen. If saved, for the most part, there is actually no irreversable damage, only some minor injuries. So you could actually survive! However, if you do not save yourself within that time, your blood will begin to boil and your heart would stop beating. :(
