The recently completed IceCube observatory is a 1 km3 neutrino detector with powerful capabilities to explore the Universe. The primary goal of IceCube is to observe cosmic neutrinos with energies in the TeV to PeV range. The IceCube detector consists of 86 vertical strings with optical sensors that are deployed at depths between 1.5 and 2.5 km in the glacial ice at the South Pole. The sensors detect Cherenkov radiation from charged particles produced in neutrino interactions. The surface array IceTop consists of 162 Cherenkov ice tanks and covers 1 km2 area. It is used for the study of cosmic rays with energies in the hundreds TeV to hundreds PeV range. IceCube has been collecting data since the deployment of the first string in 2005.Initial searches have been made for point sources of extra-terrestrial muon neutrinos and for diffuse fluxes of extra-terrestrial neutrinos of all flavours. Other topics include studies of atmospheric neutrinos, neutrino oscillations, indirect searches for Dark Matter and signatures of supersymmetry in neutrino interactions. The IceCube physics program and the latest results will be discussed.
