Putting on my author's cap

Let's say Betelgeuse goes into Super Nova/explodes or something like that in the next few months, and (by all accounts) the vision of the explosive state in the sky remains for years
; it would/could create the image of second sun in the sky.

Aside from and possible affects the explosion might have, the sight of the star exploding and
a light remaining in the sky for years would help turn a lot of hearts and minds
