A new telescope, the Antarctic Muon and Neutrino Dtector Array (AMANDA), at the South Pole is attempting to collect 'ghost' particles from some of the highest energy sources in the universe. The goal is to transform a piece of the south-polar icecap into a telescope that will map the locations of high-energy neutrinos in the sky. Ten kilometer-long strings beaded with 20 multiplier tubes along their lower 200 meters make up AMANDA. Occasionally a neutrino, racing through the 3-km-thick Antarctic icecap, interacts with an atom and spawns a muon, which emits an expanding cone of Cherenkov light as it continues along nearly the same track as the neutrino itself. By timing when this light is detected by various photomultipliers, the neutrino's origin in the sky can be determined. AMANDA records light flashes from muons created by neutrinos that have passed through the Earth to arrive at the South Pole from the northern sky. If the neutrinos come from enduring sources, such as black holes, detections will cluster around 'hot spots' in the sky. Background 'noise' from neutrinos born in Northern Hemisphere cosmic-ray showers will be distributed randomly. Other aspects AMANDA are discussed.
