The wispy particles can not be observed directly, however, so the 39 - meter - diameter, 41 - meter - high observation tank is filled with water and lined with photomultiplier tubes that can catch a distinctive glow, known as Cerenkov radiation, produced when neutrinos smash into atomic particles in the water.

Besides the advantage of needing far fewer photomultiplier tubes to detect high - energy neutrinos, Domogatsky pointed out that only a detector in the Northern Hemisphere could see neutrinos from the center of our galaxy.
