On Wednesday, one of the astronauts of the International Space Station took a picture of the bright orange light surrounding the horizon of the Earth. This orange light is known as the brightness of the highest layers of the atmosphere caused by the radiation.
This luster occurs when the molecules in the atmosphere are loaded with sunlight and ultraviolet radiation emitted by the sun. When atoms reach radiation they start to move faster and when they collide with each other, they emit energy in the form of light. The result is brilliant over the world's horizon.
The photo is taken over Australia and there is a part of the cosmic station in the foreground, but in the background there is an orange glow, millions of stars and clouds of the Earth.
This luster allowed the researchers to see how the Earth's atmosphere worked, that is, how the Earth's particles interacted with the Earth's atmosphere.
