Astronomy Cast Ep. 750: Supernova Early Warning System

Streamed live on Mar 31, 2025.

Hosted by: Fraser Cain and Dr. Pamela L. Gay

When enormous stars detonate as supernovae they release a burst of neutrinos that can be the first sign of a coming explosion. Now, astronomers have built a network to watch for that flash of neutrinos, and help direct their telescopes for when the sky show begins. Supernovae explosions occur in stages, with neutrinos being emitted hours before photons. If we can accurately detect those neutrinos, we might just be able to get on target before the light show even starts.... Maybe.
