A Digital Optical Module (DOM) is lowered into a hole in the ice at Amundsen-Scott South Pole Station as part of the IceCube project. IceCube will search for neutrinos from distant astrophysical sources, in a quest to answer questions about the origins of the universe. While trillions of neutrinos pass through the earth every second, they are difficult to detect. IceCube will use the earth as a filter, looking through the planet to the northern hemispheric skies. Eighty holes will be drilled into the ice with each hole 2.4 km deep. Sixty DOMs will be lowered into each hole and frozen into place. When neutrinos pass through ultra clear blue ice the collision produces a particle - called a muon - which radiates blue light. The DOMs will detect this light and send back data, via the Internet, to scientists around the world. Visit the IceCube website for more information.
