"At only 600-or-so light years distant, Betelgeuse will be far closer than any supernova ever recorded by humanity. It's fortunately still far away enough that it poses no danger to us." But it would be the closest star to go supernova in human history and will thus be a dramatic sight to see. "Some models "only" have Betelgeuse getting as bright as a thick crescent moon, while others will see it rival the entire full moon. It will conceivably be the brightest object in the night sky for more than a year until it finally fades away to a dimmer state."

I remember the energy in the physics department for Supernova 1987A: i can't imagine the energy and anticipation regarding Betelgeuse.
