• Betelgeuse, a red supergiant, has a close-orbiting companion star causing it to take on an egg-like shape.
• The companion star, Siwarha, is responsible for the subtle atmospheric disturbances in Betelgeuse.
• These disturbances could help explain the varying brightness of Betelgeuse.
• New radio images provide insights into the interaction between Betelgeuse and its companion star.
• The observations suggest that the companion star's gravitational pull is causing the disturbances in Betelgeuse's atmosphere.
