They will look fake because the frequencies in the images have been adjusted so we can see the aurora.
Nice find. OK, I'll go with that explanation, especially since I confirmed it elsewhere...
This is an image composite of two different Hubble observations. The auroras were photographed during a series of Hubble Space Telescope Imaging Spectrograph far-ultraviolet-light observations taking place as NASA's Juno spacecraft approaches and enters into orbit around Jupiter. The full-color disk of Jupiter in this image was separately photographed at a different time by Hubble's Outer Planet Atmospheres Legacy (OPAL) program, a long-term Hubble project that annually captures global maps of the outer planets.
NASA admits that they Photoshop almost all of their space images, but it says they have to, due to limited fields of view per photo, blur removal, and so on, and I have no problem with that per se. What I have a problem with is that the original photos are never available to the public, as far as I know, so the public is prevented from ever checking on the validity of what NASA hands them. That is a system that is begging for abuse and cover-ups, and just fuels a lot of conspiracy theories.
