More about this image
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 Earth every second, they are difficult to detect. IceCube will use 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--that radiates blue light. The DOMs will detect this light and send back data, via the internet, to scientists around the world.
