Summary:
- The asteroid Bennu, which was visited by the OSIRIS-REx spacecraft, contains evidence of ancient water channels on its surface.
- The samples collected from Bennu's surface show that the asteroid was once a more geologically active body, with flowing water and potential for past habitability.
- These findings provide valuable insights into the early formation and evolution of our solar system, as well as the potential for life-supporting environments on other celestial bodies.
