Little-studied phenomenon is called “self airglow”.
The did astronaut Alexander Gerst from the ISS while flying over Australia.
Own the glow of the Earth’s atmosphere occurs because of the connection of the nitrogen atom with an atom of oxygen and ultraviolet radiation from the sun. As a result, there is a molecule of nitric oxide and photons, which emit a bright light.
From the Ground it’s like the Aurora, although it can be seen all over the world. Orange color as in the picture, gives the sodium layer, located at an altitude of about 100 kilometers above the Earth.
Research atmospheric glow allows scientists to understand the mechanisms of particle interactions and establish some connection between what is happening in the upper atmosphere and the weather at the bottom.
As reported by “Around the world. Ukraine”, NASA astronaut showed a meeting of the Aurora and the dawn.
