The ISS image of the earth shows an unusual detail that is invisible to us

Those who live in densely populated urban space will certainly rarely see the beauty of our night sky. High concentration of light pollution protects us from the eye of the Milky Way and also deny us the light of air that is above us.

Yes, the air can sneak. The phenomenon, known as the light of radiation or the night sky, will probably be known from Earth's surface images from Earth's orbit, where the most commonly green veil lies above Earth.

The ISS astronaut recorded on October 7, 2018, 400 kilometers above Australia, where the atmosphere of our planet gives a warm orange:

Glowing occurs when the molecules of oxygen and nitrogen excite ultraviolet (UV) radiation from the sun. In this way, they smoother and give energy in the form of light waves.

From the ground, the lights of the night sky are also noticeable and remind us of its appearance on polar lights. Despite the visual similarity, both phenomena have completely different sources and provide different information to researchers. While Aurors, a faithful name, can only be seen near the poles, under the right conditions the sky light is visible everywhere on earth.

Night sky lighting is a natural source of light, which, among other things, is responsible for ensuring that the night sky is never completely dark. By the way, it is the strongest during the day, but it fades because of the brightness of the sun.

Scientists can learn much from Airglov. According to NASA, night sky light allows researchers to gain new knowledge of particle movement on the Earth-space interface and so learn more about how time is related to Earth's time.
