Explore the icy mysteries of Ceres, the largest object in the asteroid belt and only dwarf planet to be orbited by a spacecraft, in this 36-minute scientific presentation. Discover how planetary scientists solved the puzzle of why Ceres shows signs of an ice-rich interior yet its heavily cratered surface doesn't behave like soft, ice-laden terrain. Learn about groundbreaking research published in Nature Astronomy that used simulations and updated models of impure ice deformation to reveal that Ceres once hosted a subsurface ocean that froze from the top down. Understand how this freezing process concentrated impurities as the ocean solidified, creating a gradient from ice-rich surface layers to a rockier interior. Gain insights into the evolution of dwarf planets and the complex processes that shape icy worlds in our solar system through detailed analysis of this fascinating celestial body.
