PITTSBURGH (KDKA) - I like to think of the atmosphere as sort of a big sandwich since the atmosphere isn't just one layer. It has many distinct layers from the ground all the way into space. This ...

The composition and great density of 'hot Saturn' exoplanet Smertrios are a challenge to planet formation models that the ...

When the sun is relatively inactive — as it has been in recent years — the outermost layer of Earth's atmosphere cools dramatically, new observations find.

The highest layers of the Earth's atmosphere are cooling and contracting, most likely in response to increasing levels of greenhouse gases, according to a new study by scientists at the Naval ...

That reduced the density of gas at high levels where many satellites orbit, explained Thomas Woods of the University of Colorado, a co-author of the report. The decline in high-level density was ...

Lower density inthe thermosphere, which is the highest layer of the atmosphere, would reduce the drag on satellites in low Earth orbit, allowing them to stay airborne longer.

Earth’s atmosphere has five major and several secondary layers. From lowest to highest, the major layers are the troposphere, stratosphere, mesosphere, thermosphere and exosphere. "The Snow ...

When talking about the atmosphere, all weather occurs in the troposphere, the layer closest to the Earth.

These layers cool down with increasing CO 2, causing the atmospheric layers to contract. In the short-term, lower atmospheric density at high altitudes isn’t a huge concern.
