Ice CubeNeutrino Detector
atSouth Pole
QuickTime™ and a decompressor
are needed to see this picture.
Up to 86 strings of 60 optical sensors each
Depth between 1450 m and 2450 m in clear ice
If a high-energy cosmic neutrino interacts, measure Čerenkov light from showering secondary particles
Monitors all directions of sky 24 hours per day
Could it detect SETI neutrinos?
