Juno View of Europa

Flyby of Jupiter’s ice moon Europa by the Juno spacecraft. Europa is one of the largest moons of Jupiter and is considered to be one of the most promising locations for the search for extraterrestrial life. It is believed to have a subsurface ocean of liquid water, kept warm by tidal forces generated by Jupiter’s gravity. This ocean is thought to contain more water than all of Earth’s oceans combined, and its potential habitability has been the subject of much scientific investigation. Scientists are particularly interested in Europa because it is believed that the ocean in contact with its rocky mantle may provide a source of energy and nutrients that could support life. Several missions to study Europa are being planned by NASA and other space agencies, with the goal of better understanding its potential habitability and the geological processes that have shaped this intriguing moon.
