The mesosphere of Uranus is a region of balance between warming and cooling. That essentially means that nothing happens there. Except for diffusion
, the atmosphere is still. Upper reaches of the atmosphere, such as the mesosphere, can sometimes be detected by looking at the limb of a planet, as shown in this image. Unfortunately, nothing of the mesosphere can be seen in this image. For a picture showing how the temperature changes in the mesosphere, click here
