First image taken of Betelgeuse's elusive companion star

Astronomers have released the first image of Betelgeuse's elusive companion star, named Betelgeuse B, using observations from the European Southern Observatory's Very Large Telescope in Chile. The discovery, announced in a study published in the journal Astronomy & Astrophysics, confirms the presence of a stellar companion that is significantly more massive than previously thought—two to three times the mass of the Sun. This finding concludes a century-long search and challenges earlier assumptions about the star's behavior. The companion was detected during a period when it was farthest from Betelgeuse, allowing astronomers to capture clearer images despite initial concerns about Betelgeuse's intense brightness. While further observations are needed to confirm the findings definitively, researchers emphasize that the evidence strongly supports the existence of the companion.
