Europa's icy shell has floating features, potential habitability

NASA's Juno mission is studying Jupiter and its moons, focusing on Europa's potential habitability. Juno's high-definition photos revealed a surprising discovery of large pits up to 30 miles wide on Europa's icy surface, indicating potential true polar wander. Images from Juno's Stellar Reference Unit suggest present-day surface activity, including possible ice volcanoes. This research aids future missions like NASA's Europa Clipper and ESA's Juice.
