Europa is one of Jupiter's largest moons and is known for its smooth ice-covered surface, which suggests a subsurface ocean beneath. This ocean may harbor conditions suitable for life, making Europa a prime target for astrobiological studies. The moon's surface is marked by cracks and ridges, indicating geological activity. Europa's potential for hosting life has led to numerous missions planned for exploration, including NASA's upcoming Europa Clipper mission, which aims to study its ice shell and subsurface ocean in detail.
