Bennu sample reveals how water flowed through the newly forming asteroid
A study analyzing a sample from asteroid Bennu reveals that water flowed through the asteroid in restricted channels during its formation, creating distinct chemical domains. The findings provide insights into the early solar system's history and the role of water in shaping asteroids.
