To detect neutrinos—nearly massless subatomic particles produced by radioactive decay—the IceCube Observatory is a particle detector constructed from Antarctic ice and extending approximately 2,500 meters below the surface. IceCube, the first gigaton neutrino detector ever built, is designed to observe the most intense neutrinos in the universe through the ice.Location and Structure of the IceCube ObservatoryAntarctica is a valuable location due to its extreme conditions—low temperatures, low hu
