Story summary

Research reveals that dwarf planet Ceres may have once possessed key life-supporting elements, such as liquid water and organic molecules.
Data from NASA's Dawn mission indicates a subsurface ocean heated by radioactive decay, possibly sustaining life for hundreds of millions of years.
Ceres's habitable period likely spanned 2.5 to 4 billion years ago.
Currently, Ceres lacks hydrothermal activity and appears barren.
Future missions could analyze surface salts for isotopic evidence of past life, expanding the search for life beyond Europa and Enceladus.
