On Wednesday, one of the International Space Station astronauts took a photo showing bright orange light that surrounds the Earth's horizon. This orange light is known as the brilliance of the highest layers of the atmosphere that is caused by radiation.
This glow arises when the molecules in the atmosphere are charged 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 release energy in the form of light. The result is glittering above the Earth's horizon.
The photo is taken over Australia and at the forefront there is a part of the cosmic station, but in the background there is an orange glitter, millions of stars and the clouds of the Earth.
This brilliance allowed the researchers to take a look at how the Earth's atmosphere works, that is, as particles that enter into space from Earth interact with Earth's atmosphere.
