Space oceans
Space oceans are vast bodies of liquid water hidden beneath the icy surfaces of moons and other worlds scattered throughout our solar system. These subsurface oceans exist on distant moons like Europa and Enceladus, kept warm by tidal heating from their parent planets. What makes them significant is their potential to harbor life. Scientists search for space oceans because they contain more water than Earth's oceans combined and may have the chemical conditions necessary for life to exist. Missions like Europa Clipper and JUICE are now exploring these ocean worlds to understand whether they could support microbial life beyond Earth.
