Astronomers believe that Betelgeuse will go supernova within 100,000 years. Or, it has already but we won’t know for up to 600 years. When it does, and being so close, it will outshine everything but the Sun. At least until the radiation sweeps across the solar system, killing all life forms except cockroaches and Keith Richards.
