TL;DR Summary

Astronomers using ESO's VLT and its SPHERE instrument captured the clearest image yet of Betelgeuse B, the long-suspected stellar companion to Betelgeuse, now estimated to be 2–3 solar masses; this finding helps explain Betelgeuse's brightness changes and could affect its future evolution and supernova, with further observations needed to confirm its orbit.
