Does Betelgeuse even rotate? Maybe not

Betelgeuse is the well known red giant star in the corner of Orion the hunter. The name translated in some languages means “armpit of the giant,” which, I think of all the star names, is simply the best! Betelgeuse has been fascinating observers of late not only because it unexpectedly faded a few years ago but more recently a study shows it’s super fast rotational speed which is, when compared to other supergiants, is like nothing seen before.
