Hidden cozied up to Betelgeuse, a bright red star in the constellation Orion, astronomers may have finally found the giant star’s long-sought companion. This close-orbiting partner, first postulated over a century ago, matches some predictions and adds another piece to the puzzle of the mysterious supergiant star.
The images, to appear in the Astrophysical Journal Letters, show the companion only faintly. The astronomers, and others in the field, agree that the discovery, while exciting, is not definitive.
