On Wednesday, one of the astronauts of the International Space Station took a photo showing the bright orange light that surrounds the horizon of the Earth. This orange light is known as the shine of the highest atmospheric layers due to radiation.
This glow arises when molecules in the atmosphere are charged 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 Earth's horizon.
Photographs are taken from Australia, and in the foreground is part of the cosmic station, but in the background there is an orange glitter, millions of stars and Earth clouds.
This clarity allowed scientists to look at how Earth's atmosphere works, that is, the particles that enter Earth's cosmos communicate with Earth's atmosphere.
