Astronomers suspected Betelgeuse wasn't alone — and in 2024, they finally proved it. Its companion star, Siwarha (Betelgeuse B), only becomes visible at one precise point in its ~6-year orbit: maximum elongation, when it swings farthest from the supergiant's blinding glare. That's exactly when ESO's Very Large Telescope caught it on camera. The next chance to catch it again? Spring–late 2027, when it reaches the opposite side of its orbit. 🔭✨
