Astronomers have spotted new aurorae, at visible wavelengths, on all four major moons of Jupiter -Io, Europa, Ganymede, and Callisto. Surprisingly, the Jovian moons show the same auroras seen at Earth's poles, which are caused due to oxygen molecules. However, since the gases on Jupiter's moons are thinner, the red color glow is intensified by nearly 15 times more than the familiar green one.
