Jupiter and Saturn's Icy Moons Confirmed as Subsurface Ocean Worlds

Several moons orbiting Jupiter and Saturn are now understood to harbor vast liquid water oceans beneath their frozen surfaces. These so-called ocean worlds have become a major focus of planetary science due to their potential to support life. Moons such as Europa, Ganymede, and Enceladus have shown compelling evidence of subsurface seas through spacecraft observations. The discovery reshapes our understanding of where habitable environments might exist in the solar system. Scientists continue to study these icy bodies as prime candidates in the search for extraterrestrial life.
