(Visualization: NOIRLAB)]Betelgeuse - the red supergiant star in the constellation of Orion, has a companion or binary twin, astronomers have confirmed. Using the Gemini North telescope in Hawai‘i, NASA astronomers have directly imaged a faint companion hugging the swollen surface of Betelgeuse. “This can help unlock the great mysteries in our universe.”Howell plans to continue observations of Betelgeuse’s stellar companion to better understand its nature. The companion star will again return to its greatest separation from Betelgeuse in November 2027, a time when it will be easiest to detect, NASA said.
