Europa, one of Jupiter’s moons, has attracted attention for its subsurface ocean beneath an icy crust. This hidden ocean could harbor conditions suitable for microbial life. Missions like NASA’s upcoming Europa Clipper aim to study its surface and composition. Discovering life on Europa would revolutionize our understanding of biology and the potential for life beyond Earth. It raises questions about life’s adaptability and the uniqueness of Earth. Europa remains one of the most promising places in the solar system for finding extraterrestrial life.
