Is space cold?

    Temperature is a measure of how much thermal energy a substance has, and thermal energy is the movement of molecules. Because space is devoid of molecules, it therefore has no temperature whatsoever.

    Anything in space, however, is constantly bombarded by radiation coming from stars. This radiation imparts heat energy when it strikes an object (like the Earth) so anything in space would not necessarily get cold.

    If you were to put a thermometer in the darkest region of space (where there is no light), it would read about 2.7 Kelvin, or about -271 degree Celsius.  Like spiderplant said above, space itself has no temperature, but objects in space (like a thermometer) do.
