Those who live in densely populated urban space will rarely see the beauty of our night sky. The high concentration of light pollution protects us from viewing the Milky Way and also deny us the glare of the air that lies miles above us.
Yes, the air can shine. The phenomenon, also known as night light or night light, is likely to be known from Earth's Earth's records on the Earth's orbit, on which there is a mostly green stone.
An ISS astronaut photographed on October 7, 2018, 400 kilometers above Australia, which the atmosphere of our planet gives a warm orange:
Ignition occurs when the oxygen and nitrogen molecules are excited by ultraviolet (UV) radiation from the sun. In this way, they lock together and release energy in the form of light waves.
From the ground, the light of the night sky is also perceptible and reminds us of its appearance on the polar lights. Despite the visual similarity, both phenomena have completely different origins and offer researchers different information. While auror, faithful to his name, can be seen only by the poles, under the right conditions, the light of the sky is visible all over the earth.
Night lighting is a natural light source, which, among other things, is responsible for ensuring that the night sky is never dark. In fact, it is the strongest during the day, but it fades due to the sunshine.

Scientists can learn a lot from Airglow. According to NASA, night light allows researchers to gain new insights on particle motion at the Earth-to-Space interface and thus learn more about how space is related to earth's weather.
