Gemini North telescope in Hawai‘i uncovers hidden companion to Betelgeuse, shedding light on ancient stellar mystery. Using the ‘Alopeke instrument on the Gemini North telescope—funded by NASA and the U.S. National Science Foundation—astronomers have identified a companion star in a very close orbit around Betelgeuse. This breakthrough, achieved through the International Gemini Observatory (operated by […]



Summary

Astronomers using the Gemini North telescope in Hawai’i discovered a hidden companion star orbiting Betelgeuse, potentially solving a long-standing mystery about the red supergiant. The ‘Alopeke instrument, funded by NASA and the NSF, enabled the team to detect the star in a close orbit. This discovery, made possible by the International Gemini Observatory, offers new insights into the complex dynamics and evolutionary processes of Betelgeuse and similar stars, providing crucial data for future research and a better understanding of stellar behavior.
