The image of the Earth with the ISS shows some strange details that are invisible to us

Due to light pollution, many celestial phenomena remain invisible to us.Shutterstock

Those living in densely populated urban areas will certainly rarely see the beauty of our night sky. The high concentration of light pollution protects us from the view of the Milky Way and also prevents us from shining in the air that is miles away.

Yes, the air can shine. The phenomenon, also known as sky or night sky, will probably be revealed by recordings of the Earth's surface from a terrestrial orbit, on which a predominantly green veil is placed on the Earth.

The glow occurs when the oxygen and nitrogen molecules are excited by the ultraviolet (UV) rays of the sun. In doing so, they stick together and release energy in the form of light waves.

From the earth, the lights of the night sky are also perceptible and remind us by their appearance on polar lights. Despite the visual similarity, the two phenomena have completely different origins and provide different information to researchers. While auroras faithful to their name can be seen only near the poles, in the right conditions, the light of the sky is visible everywhere on the earth.

Night sky lighting is a source of natural light that must ensure that the night sky is never completely black. Incidentally, it is the strongest of the day, but it fades with the brightness of the sun.

Scientists can learn a lot from Airglow. According to NASA, the light of the night sky allows researchers to better understand the motion of particles at the Earth-space interface, and thus better understand the connection between the space weather and the Earth's weather.
