This image kicked off a series about what really happens to a body exposed to space. Sci Fi has taken a lot of liberties with this topic, i.e. your face exploding or your blood boiling. This one is called Bodies in Space: Convection, on account of the fact that there is nothing to convect your body heat into in space. The only way to lose heat is through radiation, which is a slow process. So you don’t freeze instantly, like being shot out the airlock in Battlestar Galactica. You’d more likely hang out in your underwear and not feel cold.
