[Interview+] We Don't See Supernovae In The Milky Way. Nobody Knows Why

📜 Uncovering the Next Galactic Supernova with the Vera C. Rubin Observatory https://arxiv.org/pdf/2601.12094
We should be getting 1-2 supernovae per century in a galaxy like the Milky Way. Yet, the last one observed was about 1000 years ago? Where are all the galactic supernovae? Why don't we see enough of them. Can Vera Rubin help? Finding out in this interview.

Fraser, Thank YOU!
I recall Jason Kendall stating that a massive neutrino flux -- ~10⁵⁶ -- finishes unbinding the star (not by pushing rather by heat.)

So you do get a warning before an ERB and maybe time to get under ground.
Meanwhile, the Milky Way is planning the perfect nearby supernova but in the Northern Hemisphere where Vera Rubin can’t look. And the astronomers are: “Huh. Go figure.”
I did a comprehensive survey: no astrophage in the MW. 😏
