Space discoveries reveal complex histories of Ceres and the Moon

New scientific data from recent space missions are reshaping our understanding of the early solar system and celestial bodies.

Analysis of data from the Dawn mission suggests that the dwarf planet Ceres is a complex world with an internal structure potentially consisting of a core, mantle, and crust. Researchers have identified evidence of a subsurface brine reservoir approximately 50 kilometers deep near the Occator crater. This finding may explain bright surface deposits, suggesting that cryovolcanic eruptions once brought saline material to the surface. While Ceres is currently cold and geologically quiet, it may have once possessed a subsurface ocean and conditions favorable for simple life.

Separately, geological samples returned by China's Chang’e-6 mission from the far side of the Moon are challenging the
