On Wednesday, one of the International Space Station astronauts took a photo showing a bright orange light that surrounded the Earth's horizon. This orange light is known as the highest brightness of the atmosphere caused by radiation.
This light appears when molecules in the atmosphere are filled with sunlight and ultraviolet radiation emitted by the sun. When atoms reach radiation, they begin to move faster, and when they collide with each other, they release energy in the form of light. The results sparkle above the Earth's horizon.
Photographs taken over Australia and at the forefront there are parts of the cosmic station, but in the background there is orange glitter, millions of stars and clouds of Earth.
This brilliance allows researchers to see how the Earth's atmosphere works, that is, as particles that enter space from Earth interact with Earth's atmosphere.
