In our atmosphere, there lives a small group of thin seasonal electric blue clouds!
Forming 50 miles above the poles(north and south) in summer, these clouds are known as noctilucent clouds. A recent NASA long-duration balloon mission observed these clouds over the course of five days at the mesosphere. The resulting photos, which scientists have just begun to study, will help the scientists better understand turbulence in the atmosphere. As well as in oceans, seas and lakes, and other planetary atmospheres, and may even improve weather science.

This is related to engineering because scientists and engineers, in the work field of weather, want to understand more about these type clouds.
