Astronomers found a companion star orbiting Betelgeuse, explaining its fluctuating brightness.
Astronomers have discovered a companion star orbiting Betelgeuse, a massive red supergiant in the Orion constellation.
The companion star, about 1.5 times the mass of the Sun, orbits Betelgeuse at a distance four times that between Earth and the Sun.
This discovery, made using the Gemini North telescope in Hawaii, explains Betelgeuse's varying brightness and provides insights into the star's life and expected supernova event.
