First Fridays: The Mystery of Betelgeuse

As a star, Betelgeuse is no secret. The incredibly bright shoulder of Orion the Hunter is easy to spot and carries a distinctly red hue. Still, much remains a mystery about this relatively close hypergiant star. Its sheer size makes it difficult to determine its precise distance. This makes other features of this star difficult to determine as well. However, there is no doubt that Betelgeuse is nearing the end of its stellar life cycle, and several months of consistent dimming have brought the timing of its inevitable collapse into question. In this talk, we’ll consider possible causes of this dimming, and the likelihood of seeing the supernova in our lifetime.
