Webb’s observations of extreme debris disks offer clues to the early Earth-Moon system

Bookmark this story

Astronomers are using the James Webb Space Telescope to study young star systems and their extreme debris disks, seeking evidence about how planetary systems evolve. The observations may help test theories about the early solar system, including the hypothesis that a Mars-sized body called Theia collided with the infant Earth.
