The Northern Lights, which are produced by particles from the sun interacting with the earth's magnetic field and the upper atmosphere.

A glowing region in the atmosphere could refer to phenomena such as the auroras (Northern and Southern Lights) caused by the interaction of solar wind with the Earth's magnetic field. It may also refer to noctilucent clouds, high-altitude clouds that can appear to glow in the twilight sky due to their altitude and the way they scatter sunlight.
When air pressure is constant throughout a region of the atmosphere, the region is in a state known as "hydrostatic equilibrium".
The region beyond the atmosphere is called outer space. It begins where the Earth's atmosphere ends and extends into the vacuum of space.
The jet stream is strongest in the upper troposphere, which is the region of the atmosphere located between about 7 to 12 kilometers above the Earth's surface.
The coldest region of Earth's atmosphere is the mesosphere, which is located between the stratosphere and the thermosphere. Temperatures in the mesosphere can drop as low as -90 degrees Celsius (-130 degrees Fahrenheit).
The region of the atmosphere that is evenly mixed and behaves as if it were a single gas is the homosphere. This layer extends from the Earth's surface up to about 80 kilometers in altitude and includes the troposphere and most of the stratosphere. In the homosphere, gases are well-mixed due to turbulence and convection processes.
