Story summary

A groundbreaking study reveals that Mars's moons, Phobos and Deimos, might have originated from a cycle of debris rings instead of being captured asteroids. Researchers estimate Phobos is around 100 million years old, shaped by tidal forces that caused repeated moon formation and destruction. Future missions could validate this theory, transforming our view of Mars's past.
