Well, it radiates in the infrared, I guess. But how exactly are these photons created? The atoms have some kinetic energy, which makes up the temperature. So while the atoms or molecules jitter a bit relative to each other, how does this spontaneously create a photon?

Hi Harald. Objects in a vacuum radiate by black body radiation. – John Rennie Sep 25 '15 at 05:37

The electrons are also jittering, and because these are charged particles they will emit light when accelerating. For example electrons will have certain rotational and vibrational modes of oscillation.
