This image of Neptune uses false colors to bring out the hazes of smog, which can be seen in red along the limb of Neptune, at the edge of the picture.

These hazes of smog are found at very high altitudes, over the clouds of Neptune, throughout the planet's atmosphere.

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

The bright, white clouds in this image are a patch of high altitude clouds.

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.

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.

This smog haze is found very high up in the atmosphere, 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.

A patch of bright, white clouds, very high in the atmosphere, can also be seen in this image.
