How cold is it in space ?

Post  Admin on Sun Nov 13, 2011 4:02 pm

If we put a thermometer in darkest space, with absolutely nothing around, it would first have to cool off. This might take a very very long time. Once it cooled off, it would read 2.7 Kelvin.

2.7 Kelvin is equivalent to -455 degrees fahrenheit
