Astronomers from Carnegie Mellon University have confirmed that Betelgeuse has a hidden companion star, nicknamed 'Betelbuddy,' which is a young solar-sized star. This discovery, made using NASA's Chandra X-ray Observatory and the Hubble Space Telescope, helps explain Betelgeuse's six-year brightness cycle and challenges existing models of binary star formation due to the significant mass difference between the two stars.
