IceCube neutrino detector completed

On 19 December, at the height of the antarctic summer, the IceCube neutrino detector was completed after a decade of planning, building, testing and melting holes into ice. The main IceCube detector, a massive ice-bound telescope that fills a cubic kilometre of deep Antarctic ice, now contains 5,160 optical sensors on 86 strings embedded two kilometres below the National Science Foundation’s Amundsen-Scott South Pole Station.
