Aurora borealis occurs when supercharged particles are blasted from solar winds into Earth's atmosphere, delivering spectacular light shows over the north and south poles. But Earth isn't the only planet to experience the lights: NASA has documented the phenomenon on Jupiter, too, where the aurora may be up to 100 times brighter than on Earth.

Now, scientists using X-ray telescopes have observed emissions from outside the solar system they believe are caused by aurora displays on extrasolar planets. And the aurora coming from beyond the sun's orbit may be up to 100,000 times brighter than those seen on Earth, researchers at the University of Leicester in England told
