Betelgeuse’s Hidden Companion Star Appears to Be Plowing Through the Giant’s Atmosphere and Warping Its Shape
Nature World News | 07.11.2026 06:21Betelgeuse, the red star marking Orion's shoulder, appears to have a companion that orbits so close it travels through the giant's own atmosphere. New radio observations show Betelgeuse's outer layers stretching into an oval when the smaller star, named Siwarha, is at its widest point from the giant, and relaxing toward a circle when it passes in front of or behind it.
