IceCube is a large scientific experiment located at the South Pole, designed to detect high-energy neutrinos, which are tiny, nearly massless particles that travel close to the speed of light. The facility consists of over 5,000 optical sensors buried deep in the Antarctic ice, arranged in a cubic kilometer. These sensors capture the faint light produced when neutrinos interact with the ice. The primary goal of IceCube is to help scientists understand cosmic phenomena, such as supernovae and black holes, by studying the neutrinos they emit. This research can provide insights into the fundamental processes of the universe and the origins of cosmic rays.
