Summary:
- The dwarf planet Ceres, located in the asteroid belt between Mars and Jupiter, is believed to have a subsurface ocean that is potentially habitable.
- Observations from NASA's Dawn spacecraft suggest that Ceres' interior is differentiated, with a rocky core and an icy mantle that may contain a briny, muddy ocean.
- The presence of this subsurface ocean, along with evidence of cryovolcanism and other geological activity, makes Ceres a potentially interesting target for future astrobiological exploration.
