NASA’s James Webb Space Telescope will use its 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...
