The Stanford experiment confirmed that invisible, microwave Cerenkov radiation does exist.
Aside from black-body radiation, they listed a number of other possible sources of illumination: crystalloluminescence, produced when chemicals crystallize; sonoluminescence, powered by the sound of bubbles collapsing; triboluminescence, created when rock crystals crack; and Cerenkov radiation and scintillation, both caused by the radioactive decay of elements in the vent water.
Analogous to a shock wave, this light, called Cerenkov radiation, appears when the speed of particles exceeds that of light in the medium through which they're moving.
