Temperature is a tricky concept in space, since you're in a vacuum and there's not much of a medium to really transport heat energy between objects. Therefore if you're in the light, it can heat you up. If you're in the shadow of something (or the side facing away from the light), it can get cold. This is why a lot of spaceships rotate to try and distribute the heat. Also getting rid of heat is tricky, since there's no air to heat around you (and therefore take the heat away from the object). You can also get rid of heat by radiating it, so the ISS for example has radiators with big surface area for getting rid of heat. In space though, you're also at risk of things like cosmic rays which could impact and destroy or damage DNA. If you're far enough away from a star, it's a couple of degrees above absolute zero, or about -270C.
