The mesosphere contains different kinds of gases that are mixed in the air and a deep sodium layer. Most meteors from space burn up in this layer. A special type of clouds, called noctilucent clouds, sometimes forms near... More »

The mesosphere is important, in part, because it is the layer in which most asteroids burn up. Additionally, while scientists have yet to study the phenomenon in detail, strange clouds and lightening occur in the mesosph... More »

The mesosphere is the segment of the Earth's atmosphere residing between the stratosphere and the thermosphere. It is the least-studied and least-understood layer of the atmosphere. More »

Nitrogen and oxygen are the gases that make up the mesosphere. The temperature in the mesosphere is cold enough to create ice clouds that are visible from Earth. Electrical charges within the mesosphere are also sometime... More »

The thermosphere is a layer of the Earth's atmosphere situated directly above the mesosphere and below the exosphere. The thermosphere performs several important functions, such as temperature regulation and filtering po... More »

The mesosphere, which is the third innermost layer of the Earth's atmosphere, is comprised largely of nitrogen, oxygen and carbon dioxide. Its chemical composition differs very little from that of the innermost layers of... More »
