Cold Astronomy
Astronomers are building a giant neutrino detector in the ice beneath the South Pole. Known as IceCube, it is located in the cluster of sheds and vehicles at right center of their aerial view. In this 2006 shot, IceCube was just beginning to take shape. Today, it is more than 75 percent complete, with more underway this month during the short southern summer. The detector consists of long strings of light detectors buried more than a mile beneath the ice. [Forest Banks/IceCube]
