Juno Captures Moon Shadow on Jupiter

An observer at Jupiter's cloud tops within the oval shadow would experience a total solar eclipse. Total eclipses are more common on Jupiter than on Earth — for several reasons. Jupiter has four large moons (Galilean satellites) that regularly pass between Jupiter and the Sun: in seven days, Ganymede crosses once, Europa twice, and Io four times. And since Jupiter's moons orbit in a plane close to Jupiter's orbital plane, the moon shadows are frequently cast on the planet.
