What Happens to a Human Body in a Vacuum?

Do the movies get it right? Well, not actually. Most of them depict messy, explosive endings, or other dramatic events. The truth is while being in space without a spacesuit WILL kill whoever is unlucky enough to be in that situation (unless the person gets rescued very, very quickly), their body probably won’t explode. It’s more likely to freeze and suffocate first. Still not a great way to go.
