The Witch Head nebula is illuminated by light reflected from this Class B star, which some speculate may become an oxygen-neon white dwarf. Now brighter than the alpha star of its constellation, it has at least two companion stars and is perhaps the best example of a blue supergiant. Its name from Arabic calls it the left foot of its constellation, while its location can be interpreted as where Scorpio did its stinging. For ten points, name this star in Orion which is not Betelgeuse.
