Explosions of Jupiter's aurora linked to extraordinary planet-moon interaction
Washington DC (SPX) Mar 26, 2015
On Earth, bursts of particles spewed by the Sun spark shimmering auroras, like the Northern Lights, that briefly dance at our planet's poles. But, on Jupiter, there's an auroral glow all the time, and new observations show that this Jovian display sometimes flares up because of a process having nothing to do with the Sun. Jupiter watchers have long known that the giant planet's ever-present polar auroras - thousands of times brighter and many times bigger than Earth - are powered by both electrica ... read more
