Some possible places to find life in the solar system are Europa and Ganymede, moons of Jupiter, or Titan and Enceladus, moons of Saturn. These places may have liquid water. They may be too cold to support life on their surfaces, but if they have liquid water, the water must be warm enough to support life. Astrobiologists suggest that there may be a liquid water ocean under their surfaces.
