Smog on Jupiter?

The Juno spacecraft took this image of Jupiter’s northern latitudes during a close approach 17 February, 2020. Two long, thin bands run through the center of the image from top to bottom. Juno has observed these streaks since its first close pass over Jupiter in 2016. They are layers of haze particles floating above the cloud. We’re unsure of what these hazes are made of, or how they form. (There are no known SUVs on Jupiter.) There’s been speculation that jet streams in the planet’s atmospher may influence the formation of the hazes.
