So, there are interesting things going on in the night sky right now. Betelgeuse, the shoulder of Orion the Hunter, is the dimmest it has been. This is exciting for astronomers because it could be the prelude to Betelgeuse going supernova. Or not. (Or at least not yet.) It is, apparently, visibly dimmer than it was just a few weeks ago, which is a pretty big deal, astronomically-speaking.
