NASA Telescopes Capture First-Ever Companion Star Orbiting Massive Red Supergiant Betelgeuse

Astronomers have detected a small companion star orbiting the red supergiant Betelgeuse using Hubble and Chandra observations. Dubbed “Betelbuddy,” the discovery reveals an extreme binary system that challenges existing models of stellar evolution and may offer clues to Betelgeuse’s future.Astronomers have detected a small companion star orbiting the red supergiant Betelgeuse using Hubble and Chandra observations.
