- One of the night sky’s brightest stars may have been hiding a secret
Astronomers have found clear evidence of a faint companion star, Betelgeuse B, orbiting the red supergiant Betelgeuse in Orion. Using the European Southern Observatory’s Very Large Telescope, researchers detected the companion, which is more massive than previously predicted, potentially explaining Betelgeuse’s unusual behavior and offering insights into its eventual supernova.
