Europa is not a planet but rather one of Jupiter's largest moons. It is one of the four Galilean moons (named after their discoverer, Galileo Galilei) and is the smallest of them. Europa has a smooth and icy surface with long, linear cracks that seem to extend for thousands of miles. These cracks probably formed as a result of the moon's icy crust moving over a subsurface ocean of liquid water. Europa is of interest to scientists due to this subsurface ocean, which is potentially habitable. There are many ongoing missions and proposals to explore Europa to learn more about its subsurface ocean, including NASA's Europa Clipper and the ESA's Jupiter Icy Moons Explorer (JUICE) mission. The geologic activity on Europa also indicates that its interior is still warm, which could mean that there are hydrothermal vents on its seafloor. On Earth, these vents support unique ecosystems that could potentially exist on Europa as well. Overall, Europa is a fascinating astronomical o...
