It might only last for a few weeks, but we might be able to witness a celestial even that doesn’t come around too often. We may be able to see a sister star, along with our own, if Betelgeuse, one of the night sky’s brightest stars, continues to loose mass, collapses, and goes super-nova. That event would pretty much dwarf everything I’ve ever seen in the sky with my own eyes. Scientists aren’t sure exactly when it would happen and the star’s explosion could also cause a neutron star or result in the formation of a black hole, but it sounds like they are leaning toward Betelgeuse continuing to loose mass and eventually going super-nova.
