Astronomers have finally confirmed what scientists suspected for nearly a century — Betelgeuse, one of the brightest and most famous stars in the night sky, isn't alone! Using the European Southern Observatory's Very Large Telescope (VLT), researchers captured the clearest image yet of its companion star, nicknamed "Betelbuddy." This groundbreaking discovery could explain why Betelgeuse's brightness has puzzled scientists for decades. 🔭✨

In this video, we break down what this companion star means for our understanding of Betelgeuse, why it took 100 years to find, and what it could reveal about other binary star systems in our galaxy.
