VIDEO: What Would We See If Betelgeuse Went Supernova?

You might remember a few years back when Betelgeuse dimmed considerably, likely because it expelled a large amount of matter. But this video contends that the star has destabilized and, for that reason, it may go supernova sooner rather than later. But the video also shows what it would look like from Earth, with Betelgeuse being so bright for a few months that it would be visible in the daytime and bright enough that you would cast a double shadow. Fortunately, it is far enough away that there is no danger to us from gamma rays or other radiation.
