NASA - National Aeronautics and Space AdministrationGreenbelt, MD – NASA’s James Webb Space Telescope will use its infrared capabilities to study the “ocean worlds” of Jupiter’s moon Europa and Saturn’s moon Enceladus, adding to observations previously made by NASA’s Galileo and Cassini orbiters. The Webb telescope’s observations could also help guide future missions to the icy moons.

Europa and Enceladus are on the Webb telescope’s list of targets chosen by guaranteed time observers, scientists who helped develop the telescope and thus get to be among the first to use it to observe the universe. One of the telescope’s science goals is to study planets that could help shed light on the origins of life, but this does not just mean exoplanets; Webb will also help unravel the mysteries still held by objects in our own solar system (from Mars outward).
