Neutrinos are unique cosmic messengers that provide new ways to explore the
Universe. The IceCube Neutrino Observatory, located in the ice sheet at the
South Pole, is the largest operating neutrino detector in the world.
The scientific missions of IceCube include such varied tasks as the search
for sources of cosmic rays, the observation of Galactic supernova explosions,
the search for dark matter, and the study of the neutrinos themselves.
As neutral tracers of hadronic acceleration, neutrinos may offer a new and
unique window into the problem of the origin of cosmic rays. IceCube has
observed several extremely high-energy neutrinos with energies up to several
PeV that cannot easily be explained by processes occurring in cosmic-ray
showers in the Earth's atmosphere. These events represent the first evidence
for a population of high-energy neutrinos of extraterrestrial origin. In this
talk, I will discuss these results and give a general overview of the IceCube
detector and its physics goals.
