Extensive winds of gaseous metals were identified in a massive cloud that blocked the star’s light for nearly nine months. This finding provides an exceptional opportunity to study the chaotic and dynamic processes shaping planetary systems long after their formation. Data suggest the cloud is gravitationally bound to a secondary object orbiting the star in the outer regions of its planetary system. GHOST has opened a new window to study hidden phenomena in distant stellar systems, providing key insights into the long-term evolution of planetary systems and the formation of disks around ancient stars. “This event shows that even mature planetary systems can experience large-scale dramatic collisions.
