Ganymede, the largest moon in our solar system and even bigger than Mercury, holds a fascinating secret beneath its thick, icy crust—a vast underground ocean of salty water. Scientists believe this hidden ocean could contain more water than all of Earth’s oceans combined, making it one of the most promising places in the solar system to search for extraterrestrial life. The immense pressure and potential warmth from the moon’s core may allow liquid water to exist beneath the frozen surface, creating an environment where microbial life could potentially thrive. This discovery has turned Ganymede from just another icy moon into a key target for future space missions seeking to unravel the mysteries of life beyond Earth.
