Auroras spotted at the poles of Jupiter

Here on Earth, the ethereal light-shows known as auroras usually mirror each other at the north and south poles but hundreds of millions of miles across space - on Jupiter - the auroras are dramatically different.

Using x-ray observations taken by NASA, researchers built maps showing x-ray hot spots at Jupiter's north and south poles.

They found that the auroras behave independently of each other.

At the planet's south pole, the x-rays pulsated at consistent intervals but at the north pole, the emissions flared erratically, fluctuating in brightness.

The auroras are also much larger on Jupiter - with each one measuring about half the size of Earth.

To further study the auroras, scientists will combine new x-ray data with information from NASA's Juno Mission - which is currently orbiting Jupiter.
