IceCube Neutrino Observatory

Definition

The IceCube Neutrino Observatory is a large-scale scientific facility located at the South Pole, designed to detect high-energy neutrinos produced by cosmic events such as supernovae and gamma-ray bursts. Utilizing a cubic kilometer of clear Antarctic ice as a detection medium, the observatory employs thousands of optical sensors embedded in the ice to capture light from neutrino interactions, providing critical insights into the universe's most energetic phenomena.
