Other Planets have Aurorae too! Even Mars!

With all the talk of the large geomagnetic storm of the past few days, it’s important to understand that other worlds have beautiful auroral activity as well.  Being on Earth and seeing the gorgeous displays that result from our magnetic field protecting us from harmful solar radiation, the best views come from Earth.  But there are several other places in our own solar system that have aurora.

Aurora are everywhere, and give us clues to the atmospheric and magnetic environments around planets and moons.
