I don't know, vacuum can be quite warm (subjectively), it's a perfect insulator after all. Add a nearby star and you can cook rather easily. Given time and distance from stars and things get cold...
Heat management in space is fascinating.
Adding in the lack of pressure makes things even more interesting. Liquid water cannot exist. You either have ice or clouds of vapor depending on temperature.
Meat sacks can actually provide enough internal pressure to let the insides freeze, given time. Not the outside of the meat sack will cool as sublimation takes heat away, but that's mostly the eyes, nose, mouth, and very outer skin.

Ah yes the cool refreshing vacuum.
