Fake news.  All those photos are greatly edited.

"Since July of last year, NASA’s Juno spacecraft orbiting Jupiter has returned batch after batch of grainy, raw images. When a new set arrives, the images are quickly uploaded to a public website, where a band of space enthusiasts, sprinkled around the world, grab them and get to work. They stitch the images together, make a few color corrections, and start sprucing. Some adjustments to contrast here, a little brightening there. "

It looks like the colors are enhanced. That really doesn't take anything away from the photos.

Not much different than the Voyager photos from 1979.  Same concept, thousands of small images knitted together with computer enhancement in several spectrums so you can see details more easily.  Quite a bit more detail in in the weather patterns in some these photos, though.

I remember my first telescope when I was nine.  I was very disappointed that Orion's nebula didn't glow with visible gases everywhere, in warm hues of orange, yellow, and pink, like the pictures in my books did.  All I saw were vague hints of cold bluish and greenish wisps.   I didn't understand about time-exposure photos back then.

Nevertheless, it was still very cool to point my scope at Jupiter, be able to see one or two equatorial bands (not as dramatic as in the photos), and see at least two moons at any one time.  I could also see Saturn's rings pretty well.
