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.
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.
Astronomers using the European Southern Observatory's Very Large Telescope with the SPHERE instrument released the clearest image yet of Betelgeuse B, a possible companion star, suggesting Betelgeuse is a binary system. Betelgeuse B is estimated to have 2–3 times the Sun’s mass. Follow‑up observations over a full orbit are needed to confirm the companion's path and to assess any influence on Betelgeuse’s future supernova.
A sharp image from ESO's Very Large Telescope reveals a faint companion near Betelgeuse, named Betelgeuse B: a young, hot star about 2.6–3.1 solar masses orbiting the red supergiant at roughly the Saturn–Sun distance. The finding, supported by two independent image-processing methods and strong statistical significance, suggests Betelgeuse is a binary/multiple system; although orbital motion still needs to be observed to confirm binding, the result has important implications for how massive stars form and how their winds and mass loss operate.
Astronomers using the Very Large Telescope’s SPHERE instrument in Chile captured the strongest direct evidence yet that Betelgeuse has a faint stellar companion, Betelgeuse B, making Betelgeuse a binary system. The image suggests Betelgeuse B is about two to three times the Sun’s mass—more massive (and brighter) than earlier predictions—though researchers will need to observe Betelgeuse B again in about a year to confirm it's gravitationally bound and to understand how its presence could influence Betelgeuse A’s future evolution.
