IceCube at the South Pole is the world’s leading high-energy neutrino observatory. Completed in 2010 and taking data continuously since then, IceCube has provided the first evidence for the existence of a diffuse flux of high-energy cosmic neutrinos, a billion times higher in energy than the neutrinos produced by our Sun. The discovery of cosmic neutrinos was named the “2013 Breakthrough of the Year” by the IOP journal Physics World. The distribution of the arrival directions of the cosmic neutrinos indicates extragalactic origin, although their progenitors remain a puzzle. Recently, IceCube succeeded in another breakthrough, identifying for the first time an astronomical high-energy neutrino source – with aid of a multi-wavelength campaign of observations by optical, infrared and gamma-ray telescopes. The two breakthrough discoveries open a new window on the high-energy universe. The colloquium will review the rationale for neutrino astronomy, discuss selected results from IceCube and the long-term vision for a second generation IceCube observatory.
