Supernovae are the most luminous souce of neutrinos in the universe. It was shown that neutrinos have finite masses and convert each other from the solar and atmospheric neutrino observations. The time profile and energy spectrum of neutrino burst from supernovae should be greatly modified by this effect. We review how this conversion happens in a supernova mantle and how the burst will be detected by SK (Super-Kamiokande) and SNO (Sudbury Neutrino Observatory). We show that implications for neutrino parameters (mass hierarchy and the mixing angle between mass eigenstate ν1, ν3), are obtained if a supernova appears at Galactic Center. We also discuss effects of neutrino oscillation on the supernova relic neutrino observations. In the end, we discuss the anisotropic neutrino radiation from the rotating stellar cores, which will be important to clarify the explosion mechanism of core collapse supernovae.
