Astronomy Cast Ep. 750: Supernova Early Warning System

https://www.youtube.com/watch?v=AEugVwlTunc


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.
