The bright, cool supergiant Betelgeuse became historically faint in February 2020. Various explanations have been offered for its unusual behavior - including conjectures this foreshadows an imminent supernova event. Direct imaging, spatially resolved spectroscopy, polarization measures, infrared, optical and ultraviolet spectra and more help us to unravel what happened to the star. The current state of the star as well as new results from spectroscopic observations with HST will be reported in advance of the next optical minimum expected in the spring of 2021.
