The IceCube Neutrino Observatory encompasses a cubic kilometer of pristine ice deep below Antarctica's surface and next to the NSF Amundsen-Scott South Pole Station. In this illustration, based on an aerial view near the South Pole, an artistic rendering of the IceCube detector shows the interaction of a neutrino with a molecule of ice. The display pattern is how scientists represent data on recorded light. Every colored circle represents light collected by one of the IceCube sensors. The color gradient, from red to green/blue, shows the time sequence.
