Water is essential for life as we know it, and scientists have long been searching for water beyond Earth. Mars, for example, has evidence of ancient riverbeds and ice deposits, suggesting that liquid water once flowed on its surface. The search for water on Mars is a critical aspect of understanding whether the planet could have supported life in the past.
In addition to Mars, moons like Europa (one of Jupiter’s moons) and Enceladus (a moon of Saturn) are believed to harbor subsurface oceans of liquid water beneath their icy surfaces. These moons are prime targets for astrobiology research, as they could provide the necessary conditions for microbial life.
