Jupiter and its aurora

An article published in the journal “Science” describes a research on the influence shown on the aurorae at Jupiter’s poles by its moons Io and Ganymede. A team led by Alessandro Mura of the National Institute for Astrophysics in Rome, Italy, analyzed data collected in particular from the NASA’s Juno space probe’s JIRAM instrument, discovering that Io leaves a series of long traces in Jupiter’s aurorae while Ganymede leaves a double “shadow” in them.
