On Wednesday, one of the astronauts of the International Space Station made a photograph showing a bright orange light surrounding the Earth's horizon. This orange light is known as the brilliance of the highest atmospheric layers due to radiation.
This glow appears when the molecules in the atmosphere are filled with sunlight and ultraviolet radiation emitted by the sun. When atoms reach the radiation, they begin to move faster, and when they collide, they release energy in the form of light. The result is glittering over the horizon.
Photo taken over Australia and in the foreground is part of a cosmic station, in the background there is an orange glitter, millions of stars and clouds of the Earth.
This brilliance enabled the researchers to see how the earth's atmosphere works, that is, when particles entering the universe affect the Earth's atmosphere.
