A dwarf planet has dirty depths, model suggests
Briefly

Recent modeling of Ceres suggests that beneath its surface lies a frozen ocean composed mainly of pure water ice, but as you delve deeper, ice becomes increasingly mixed with impurities. This gradual transition from purity to a dirtier state aligns with previous research that had produced conflicting results regarding the ice's composition. The stratification observed within Ceres indicates a complex geologic history and potentially insights into its formation and evolution.
This study serves to bridge the conflicting evidence surrounding Ceres' icy content, providing a clearer picture of its internal structure. The idea of a layered ocean under the surface offers implications not only for Ceres itself but also for understanding other similar celestial bodies in the solar system. As we explore further, the chemical interactions occurring in the deeper segments of its ocean could reveal clues about the conditions that prevailed during Ceres' development.
