NASA’s Juno Spacecraft Detects Callisto’s Aurora, Completing Jupiter’s Galilean Moons Set

Juno finds final missing auroral signature from Jupiter's largest moons - Tech and Science Post

Jupiter hosts the brightest and most spectacular auroras in the solar system. Near its poles, these shimmering lights offer a glimpse into how the planet interacts with the solar wind and moons swept by Jupiter’s magnetic field. Unlike Earth’s northern lights, the largest moons of Jupiter create their own auroral signatures in the planet’s atmosphere—a phenomenon that Earth’s moon does not produce. These moon-induced auroras, known as “satellite…

NASA’s Juno Spacecraft Detects Callisto’s Aurora, Completing Jupiter’s Galilean Moons Set

NASA’s Juno spacecraft has captured Callisto’s elusive auroral footprint, completing the “family portrait” of Jupiter’s Galilean moons. Each moon carves its own aurora into the gas giant’s poles, revealing how they interact with Jupiter’s powerful magnetosphere. Callisto’s faint arc appeared during a 2019 flyby, finally confirming its mark.
