At least five moons of planets in the outer solar system may harbor subsurface liquid water oceans. The total volume of liquid water on these worlds is likely in excess of 100 times the volume of all the liquid water on Earth. These oceans have persisted for much of the history of the solar system and as such they present highly compelling worlds in our search for life beyond Earth. In this presentation Dr. Hand will explain the science behind why we think we know these oceans exist and what we know about the physical and chemical conditions that likely persist on these worlds.
