Thermal Radiation and Heat Engines

  1. Apr 6, 2009 #1
    Hey all,

    This is a simple question:

    Lets say we have a solid hot-body in outer-space thats emitting thermal radiation. Assuming that it doesn't sublimate, will it simply radiate black-body radiation until it reaches absolute zero? This doesn't sound right.

    well outerspace isnt absolute zero, i would assume it would reach equilibrium by radiating its heat. at that point it would be the temperature of space (somewhere like 4K i think)
