MadSci Network: Earth Sciences |
When we feel nice and warm on Earth it is because we are surrounded by an ansulating blanket - the atmosphere. The air around us becomes warm from the sunshine and when the air touches our skin we feel the warmth. If there were no air, as in outer space, we would loose heat through the skin and freeze badly in a short time. In direct sunshine in outer space things can get very hot because the objects pick up and store the heat from the suns rays, but on the side where there is shade (on the back of a space-ship, say) it quickly gets very cold.
