Supernova 1987A became a milestone in physics and astronomy. The most important things that have been learned from it, the most important problems yet to be solved and the prospects for learning important new physics from future observations of nearby supernova explosions are shortly summarized.

We reanalyse the limits on the gravitino mass m 3/2 in superlight gravitino scenarios derived from arguments on energy-loss during gravitational collapse. We conclude that the mass range 10 −7 eV ≤ m 3/2 ≤ 2.2 × 10 −6 eV is excluded by SN1987A data. In terms of the scale of supersymmetry breaking Λ, the range 70GeV ≤ Λ ≤ 300GeV is not allowed.
