Ice Cube: 10 Years of Neutrino Research from the South Pole

It was the beginning of a grand experiment unlike anything the world had ever seen. Ten years ago, on May 13, 2011, the IceCube Neutrino Observatory fully opened its eyes for the first time. Over the course of the previous seven years, dozens of intrepid technicians, engineers, and scientists had traveled to the South Poleone of the coldest, driest, and most isolated places on Earthto build the biggest, strangest telescope in the world. Crews drilled 86 holes nearly twoandahalf kilometers deep and lowered a cable strung with 60 basketballsized light detectors into each hole. The result was a hexagonal grid of sensors embedded in a cubic kilometer of ice about a mile below the surface of the Antarctic ice sheet. On December 18, 2010, the 5, 160th light sensor was deployed in the ice, completing the construction of the IceCube Neutrino Observatory. The purpose of the unconventional telescope was to detect signals from passing astrophysical neutrinos: mysterious, tiny, extremely lightweight pa
