The Supernova Early Warning System

Alec Habig and Kate Scholberg describe the Supernova Early Warning System (SNEWS), an international network of neutrino detectors set up to provide a fast alert to the astronomical community if the participating experiments detect the distinctive burst of neutrinos from a stellar core collapse in or near the Milky Way.
