Summary:
- The Hubble Space Telescope has observed the wake of a hidden companion star to the famous red supergiant star Betelgeuse, located in the Orion constellation.
- The companion star is believed to be a smaller, more compact star that is orbiting Betelgeuse and interacting with the larger star's stellar wind, creating a visible wake or trail.
- This discovery provides new insights into the complex dynamics and interactions within binary star systems, which can help scientists better understand the evolution of massive stars and their eventual fates, such as supernovae explosions.
