High energy neutrinos from the Cosmos? Recent results from the IceCube Neutrino Telescope

The neutrino observatory IceCube is opening a new observational window
to the Universe. IceCube, which has been fully constructed in the
icecap at the South Pole, is taking data since Spring 2011 in full
configuration. The first years of data reveled the existence of
extremely high neutrinos at the PeV scale. The observed diffuse
neutrino flux is with high probability of astrophysical origin. In
this talk I will summarize the recent observation and discuss the
prospect for point source searches.
