New imagery from the Very Large Telescope (VLT) indicates that the bright star in the Orion constellation is actually a binary system, consisting of two stars rather than a single stellar giant.
VLT Imagery Confirms Binary System
The discovery relies on high-resolution images that provide the clearest evidence to date of an elusive companion orbiting Betelgeuse. According to reporting from Reuters and Live Science, these images reveal that the red supergiant is not alone, effectively disguising two stars as one to previous observers.
Betelgeuse is a red supergiant, a class of star characterized by immense size and luminosity. This finding follows centuries of research into the star’s behavior, including its irregular dimming events.
