Neptune's Smog Hazes

This image of Neptune uses false colors to show where the smog is. The smog of Neptune can be seen in red along the edge of the image.

These hazes of smog are found at very high altitudes, over the clouds of Neptune. Even though the smog can only be seen in red along the edge of the picture, the smog exists through the entire atmosphere of Neptune.

The smog is composed of molecules called "hydrocarbons", as most smog is.

The bright, white clouds in this image are a patch of clouds very high in the atmosphere.
