GoKawiilSix Icy Moons Confirmed as Hidden Ocean Worlds, Reshaping Search for Life
Data from the Voyager, Galileo and Cassini missions, combined with modeling and observations from Hubble and Webb, has revealed that at least six moons and dwarf planets in the outer solar system—including Europa, Enceladus, Titan, Mimas and Callisto—harbor liquid water oceans beneath their icy surfaces. Even Pluto is now considered a candidate ocean world, suggesting many undiscovered Kuiper Belt objects could conceal similar hidden seas.
