Betelgeuse Goes Supernova

Betelgeuse is roughly 640 light years from earth, located in the Orion Constellation. The left shoulder actually. Betelgeuse varies in brightness because it’s a dying, red supergiant star with a diameter some 700 times larger than our Sun. Humans would be able to see the supernova in the daytime sky for roughly a year, he says. And it would be visible at night with the naked eye for several years, as the supernova aftermath dims. It will turn into a Neutron star or a Black Hole. When will it happen? The answer has been: Maybe today. Maybe a thousand years from now. Any day now in Cosmological terms.
