 In another false-color image obtained by infrared interferometry two large, bright star spots spanning ~10 milliarcseconds are visible on the surface of Betelgeuse, possibly representing enormous convective cells rising from below the supergiant's surface.Because of these, Betelgeuse appears to change shape periodically, with a complex, asymmetric envelope that is the product of a colossal ongoing loss of mass, as huge plumes of gas are continuously expelled from its surface (see "Tony and the Beetles" by Philip K. Dick, below).There is some evidence for the existence of close stellar companions of Betelgeuse, orbiting it "within" its gaseous envelope (see "From a Changeling Star" by Jeffrey Carver and the television series "Space Battleship Yamato", below).
