Searching for Water in the Solar System and Beyond: As our missions explore our solar system and search for new worlds, they are finding water in surprising places. Water is but one piece of our search for habitable planets and life beyond Earth, yet it links many seemingly unrelated worlds in surprising ways.

In this artist's concept, the moon #Ganymede orbits the giant planet Jupiter. The Hubble Space Telescope observed aurorae on the moon generated by Ganymede's magnetic fields. A saline ocean under the moon's icy crust best explains shifting in the auroral belts measured by Hubble.
