New ALMA images reveal hot regions and a boiling exterior on the star, which possesses nearly 20 times the mass of the sun. Astronomers are investigating a stunning anomaly in the star's appearance, suggesting that a nearby companion may be responsible for shaping these atmospheric patterns.Why it mattersBetelgeuse is a massive red supergiant. Understanding its atmospheric instability helps astronomers predict the behavior of stars nearing the end of their life cycles.What is confirmedBetelgeus
