There’s no need to worry about the stellar explosion. A supernova has to happen extremely close to Earth for the radiation to harm life — perhaps as little as several dozen light-years, according to some estimates. Betelgeuse is far outside that range, with recent studies suggesting it sits roughly 724 light-years away, well outside the danger zone.
But the supernova could still impact Earth in some surprising ways. For example, Howell points out that many animals use the moon for navigation and are confused by artificial lights. Adding a second object as bright as the moon could be disruptive.
