The neutrino, the lightest and most weakly interacting particle of the
Standard Model has revealed itself as the messenger of the most
exciting news of the last decade in particle physics: there is Physics
Beyond the Standard Model. All this thanks to the quantum-mechanical
phenomenon of flavour oscillations which is intrinsically connected to
the question of neutrino mass and which has been observed in: (i) The
deficit of neutrinos born in nuclear processes that make the sun
shine;(ii) The deficit of neutrinos of produced in the Earth
atmosphere by cosmic ray interactions;(iii) The disappearance of
neutrinos produced at reactors and accelerators after traveling over
hundreds of kilometers.  Neutrinos have also an important role in
Astrophysics and Cosmology as well as in the study of our own planet.
In this talk I will present some of these observations which have
made of the neutrino a central player in the area of Astroparticles
during the last years.
