But, at our distance, we won't be in any danger because the vast amount of energy released by the supernova will be spread over a bubble of space with a surface area of more than a million square light-years.
Betelgeuse is a red supergiant that has evolved from an O-type main sequence star. Its core will eventually collapse, producing a supernova explosion and leaving behind a compact remnant. The details depend on the exact initial mass and other physical properties of that main sequence star. The initial mass of Betelgeuse can only be estimated by testing different stellar evolutionary models to match its current observed properties. The unknowns of both the models and the curr…
