Those who live in a densely populated urban spot rarely see the beauty of our night sky. The high concentration of light pollution disrupts the appearance of the Milky Way and also denies the glow of the air that lies a mile above us.
Yes air can shine. The phenomenon, also known as air lights or night light, is likely to be known from recordings of Earth's surface of the Earth's orbit, which is largely green on the ground.
ISS's astrons took a shot on October 7, 2018, 400 kilometers above Australia, where the atmosphere of our planet gives a warm orange away:
Glowing occurs when oxygen and nitrogen molecules are excited by ultraviolet (UV) radiation from the sun. In doing so, they get stuck together and give them the best of energy, in the form of light waves.
From the ground, nightlight lights also discover and remind us of their appearance on polar lights. Despite the visual similarity, the phenomena have a completely different source of origin and provide different information to researchers. Although a auroras, loyal to its name can not be seen, close to the poles, under the correct conditions, air light is visible everywhere on the ground.
Nightlight is a natural light source, which is among other things, which is responsible for ensuring that night air is never completely dark. By the way, this is the strongest daytime, but it disappears due to the brightness of the sun.

Scientists can learn a lot of the Airglow. According to NASA, nightlight light allows researchers to have a new insight into moving the particles in the Earth interface to space, thereby learn more about how the weather is related to Earth's weather.
