Abstract
The appearance in February 1987 of a naked-eye supernova in a nearby galaxy to our own was the first supernova of this brightness for 383 years. Neutrinos detected from the supernova marked the start of the subject of neutrino astronomy. The light from the star was a uniquely bright probe to the regions of interstellar space, in our Galaxy and another, and to the intergalactic space between them.
