Astronomers Capture Clear Image of Betelgeuse's Hidden Companion Siwarha
Using ESO's Very Large Telescope with the SPHERE instrument, astronomers obtained the clearest image yet of Betelgeuse's suspected companion, Betelgeuse B (Siwarha), estimated at 2–3 solar masses. While it remains to confirm whether the companion is gravitationally bound, the discovery reshapes our understanding of Betelgeuse’s environment and could influence models of its future evolution and mass loss as it heads toward a supernova in the distant future.
