Tiny Enceladus exercises giant electromagnetic influence at Saturn

A major study by an international team of researchers using data from the NASA/ESA/ASI Cassini spacecraft has revealed a lattice-like structure of crisscrossing reflected waves that flow downstream behind the moon in Saturn’s equatorial plane, but also reach up to very high northern and southern latitudes. The analysis of data from four instruments aboard Cassini, collected over the mission’s 13-year duration, demonstrates the crucial role that Enceladus plays in circulating energy and momentum around Saturn’s space environment.
