Paula Chadwick of the University of Durham in England and her colleagues recorded flashes of blue light known as Cerenkov radiation, which is produced when Earth's atmosphere stops incoming gamma rays. 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. |
