GermanyResearchers believe they have solved a decades-old mystery surrounding the red supergiant star Betelgeuse by identifying evidence of a companion star. The findings, published in 'The Astrophysical Journal Letters,' suggest the presence of a faint star orbiting Betelgeuse, which could explain some of its periodic brightness fluctuations. This discovery would resolve a question that has puzzled astronomers for over 100 years. Betelgeuse, located in the constellation Orion, has shown significant changes in brightness, including a notable dimming event in 2019–2020 known as the 'Great Dimming.' While this was initially thought to signal the star’s imminent supernova explosion, it was later attributed to a cloud of dust ejected by Betelgeuse. However, the new study suggests that a companion star might be responsible for other observed variations in light. The research used advanced imaging techniques at the Gemini-North Telescope, though atmospheric interference made the observations challenging.
