Europa's Moons and Missions

The video explores Europa, one of Jupiter's Galilean moons, known for its icy surface and potential subsurface ocean. Observations from spacecraft, particularly NASA's Galileo, reveal Europa's smooth surface and mysterious features like lenticuli. Evidence suggests a global salty ocean beneath the ice, possibly supporting life. Future missions, including NASA's Europa Clipper and ESA's JUICE, aim to further investigate Europa's habitability.
