For more than a decade--in the most inhospitable place on Earth--scientists have been building an observatory to search for a "ghost." The IceCube Neutrino Observatory is a massive telescope embedded in the Antarctic ice near the South Pole. Its aim: to search for elusive subatomic particles called neutrinos that have made their way to Earth from distant cosmic events like supernovae and black holes. Neutrino research is pushing the astrophysics envelope, and should provide answers to key questions about dark energy and dark matter.
