Jupiter has a MUCH stronger magnetic field than Earth does, and the Aurora’s it produces have been known about for a while. This image above from Hubble though is one of the most incredible I’ve seen!
More from NASA/Hubble HERE. Next week a new spacecraft named JUNO will go into orbit around Jupiter, and we will learn a lot more about the large gas giant.
FYI- Jupiter is on the far side of its orbit from us and appears about as dim as it gets, but you can see it in the evening sky. See the image below from Sky and Telescope Magazine.
