   Could water sustain extraterrestrial life?

   • Water has been a major driver of exploration of the solar system. Essential to the formation of all known life, evidence of stable liquid water elsewhere could indicate an environment beyond Earth that could sustain the formation of extraterrestrial life.

   What is extraterrestrial liquid water?

   • Extraterrestrial liquid water is water in its liquid state that naturally occurs outside Earth. It is a subject of wide interest because it is recognized as one of the key prerequisites for life as we know it and is thus surmised to be essential for extraterrestrial life.

   Does water vapour exist?

   • Water vapour is sometimes considered conclusive evidence for the presence of liquid water, although atmospheric water vapour may be found to exist in many places where liquid water does not. Similar indirect evidence, however, supports the existence of liquids below the surface of several moons and dwarf planets elsewhere in the Solar System.

   Why are scientists interested in extraterrestrial bodies?

   • Beyond Mars and the Moon, scientists have hypothesized sources of water further afield from Earth. The large outer planets of our solar system, Jupiter and Saturn, have been viewable by telescope for centuries, as have many of their very large moons. As such, scientists have been fascinated by these extraterrestrial bodies for some time.

   Both show strong evidence of a global subsurface ocean beneath a kilometers-thick water-ice crust—but how can we access this liquid water? Various concepts for ocean access have been investigated over the past decades, ranging from robots that descend through crevasses to drills of varying types.

   Extraterrestrial liquid water in the Solar System is likely uncommon, although it has been hypothesized to exist in some of its moons, and to have formerly existed on Mars and Venus. Extrasolar liquid water has not yet been confirmed to exist. The following list contains candidates that meet the following criteria:
