A considerable amount of work has been devoted in recent years to the
progenitors of the various types of stellar explosions, be it novae, supernovae
or gamma-rays bursts. Theoreticians are actively exploring the different
ingredients (mass, mass loss, metallicity, rotation, binarity, magnetic field)
affecting the appearance of a massive star just before the time of its explosion
(SNII, SNIb, SNIc, long gamma-ray burst), as well as the different pathways
leading to explosions in binary systems (novae, SNIa, short gamma-ray burst). On
the observationnal side, several progenitors of SNII have already been
identified in deep HST images of their host galaxies and tantalizing hints on
the role of metallicity in shaping the properties of SN types have been obtained
recently. Reliable statistics for various SN frequencies as a function of type
of the host galaxy have been established at low redshift and this type of work
is currently extended to higher redshifts.
