So we’re still where we were two weeks ago: Betelgeuse might explode tomorrow. It might explode a hundred thousand years from now. But if it does explode soon, we will get the best look we’ve ever had at how stellar explosions work.
I was peripherally involved in this research, which detected some of the highest energy photons every seen from a gamma-ray burst.
GRBs are dangerous. They can kill. But it’s rare. There is one candidate nearby that could be dangerous. But we’re still figuring out whether it is.
I checked the calculations myself and this does appear to be accurate…
