Jupiter's Europa is one of the largest moons of Jupiter, the fifth planet from the Sun. It is known for its smooth, icy surface, which is believed to cover a vast ocean of liquid water beneath. This ocean makes Europa a key target in the search for extraterrestrial life. The surface of Europa is marked by cracks and ridges, suggesting that the ice is constantly shifting. Scientists think that the interaction between the ocean and the moon's rocky mantle could create the right conditions for life. Future missions, like NASA's Europa Clipper, aim to explore this intriguing moon further.
