Velcroman1 (1667895) writes "Researchers at the University of Wisconsin are putting the finishing touches on the IceCube Neutrino Detector, a giant underground telescope buried beneath the South Pole to help understand said phenomenon. Accordingly called the IceCube Neutrino Observatory, completion is expected to occur at 8 p.m. CST, once the last of more than 5,000 optical sensors is buried as much as two miles below the permanent ice cap covering Antarctica. The sensors are buried over one square kilometer of Antarctica's frozen tundra; weight-wise, that's a gigaton of ice. "The detection of these neutrinos will resolve the century-old question of the origin of cosmic rays," said researcher Francis Halzen in an interview from his cold base at the South Pole. "Other missions include the search for dark matter and for supernova explosions inside our own Galaxy. It is however a discovery instrument, and surprises are what we really hope for.""
