Core-collapse supernovae (SNe) are powerful neutrino sources and as such
important targets for the growing array of neutrino observatories. We review
the current status of SN theory and the expected characteristics of the
neutrino signal. After recalling what we have learned from SN 1987A and general
SN properties we review the physics potential of a future galactic SN
observation.Comment: Contribution to TAUP 200
