One of the most famous stars in the sky has been hiding a secret for a century. 🔭⭐
Astronomers have suspected for 100 years that Betelgeuse — the bright red star in Orion's shoulder — wasn't alone. Using the European Southern Observatory's Very Large Telescope, scientists just captured the clearest image ever of its hidden companion, "Betelgeuse B." Betelgeuse itself is a dying supergiant, and when it finally explodes, it'll be visible in broad daylight for weeks.
Key facts:
• Companion star confirmed: July 2026, via ESO's VLT
• Betelgeuse B: 2-3x the mass of our Sun
• Betelgeuse: 724 light-years away, nearing a supernova explosion
