CONFIRMED *** GANYMEDE IS THE ONLY MOON IN OUR SOLAR SYSTEM THAT HAS A MAGNETIC FIELD ***

Interesting possibility for a future human habitat.

Some scientists have seen the ultimate sky show, and the fact that the sky isn't ours only makes it cooler. Gas giant Jupiter features some epic aurora beyond-borealis (and ultra-australis) and the causes make ours look like two small sparklers in a bucket of water.



On Earth auroras are caused by the interaction between the solar wind and the upper atmosphere. Energetic particles slam into the upper atmosphere, slowing down and losing energy to electrons in the atoms already there. More electrons gain energy from magnetic fields in the solar wind particles violently rewiring themselves and our magnetosphere. Excited electrons from both processes then fall back down to their original state, emitting light as they go - different colors coming from different materials in the atmosphere.
