The discovery of high-energy neutrinos of cosmic origin aims atproviding an unambiguous signature for acceleration of hadrons and this way con-tributing to address the question of the origin of cosmic rays. Due to the smallcross-section and low expected fluxes this is a difficult task and no indication ofcosmic neutrino signals has been collected so far. Here we review the perspectivesof opening a new observational window with the establishment of neutrino astro-physics.
