The giant star Betelgeuse may have a companion that dives straight into its outer layers. Every 2000 days, it rushes through the gaseous envelope, leaving a fiery trail like a boat on water. This explains the star's mysterious pulsations and will help predict when it will go supernova.
🎯 Betelgeuse is so vast that if you placed its center where the Sun is, its surface would reach the orbit of Jupiter.
🎬 In the novel 'The Hitchhiker's Guide to the Galaxy,' one of the planets orbits Betelgeuse.
