IceCube Detects Neutrinos (image) DOE/Lawrence Berkeley National Laboratory Share Print E-Mail Caption IceCube's 5,160 digital optical modules are suspended from 86 strings reaching a mile and a half below the surface at the South Pole. Each sphere contains a photomultiplier tube and electronics to capture the faint flashes of muons speeding through the ice, their direction and energy -- and thus that of the neutrinos that created them -- tracked by multiple detections. At lower left is the processed signal of an energetic muon moving upward through the array, created by a neutrino that traveled all the way through the Earth.
