IceCube, the South Pole neutrino observatory, is a cubic-kilometer particle detector made of Antarctic ice and located near the Amundsen-Scott South Pole Station. It is buried beneath the surface, extending to a depth of about 2,500 meters. A surface array, IceTop, and a denser inner subdetector, DeepCore, significantly enhance the capabilities of the observatory, making it a multipurpose facility.


On December 18, 2010, just after 6 pm New Zealand time, the last of IceCube’s 86 strings was lowered into the Antarctic ice. Seven austral summers of construction had come to an end, and IceCube was completed a decade after the collaboration submitted the proposal.
