IceCube is an enormous particle detector located deep in the ice at the South Pole. IceCube is the world's largest neutrino detector, encompassing a cubic kilometer of ice. The IceCube telescope is a powerful tool to search for dark matter and could reveal the physical processes associated with the enigmatic origin of the highest energy particles in nature. Buried deep within the East Antarctic ice sheet at the South Pole, a giant high-energy neutrino observatory due for completion in 2009 could provide scientists, including from Europe, with an unprecedented window to the Universe, as well as a means to answer some of the most fundamental questions of astrophysics and cosmology
