On Wednesday, one of the international space station astronauts took a photo of glowing orange light that surrounds the Earth's skyline. This orange light is known as the brightness of the highest atmospheric layers that is caused by radiation.
This glow occurs when molecules in the atmosphere are loaded with sunlight and ultraviolet radiation emitted by the sun. When the atoms reach the radiation, they begin to move faster, and when they collide with each other, they release the energy in the form of light. The result is shining above the Earth's horizon.
The picture is taken over by 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 the clouds of the Earth.
This glow allowed scientists to look at how Earth's atmosphere works, that is, the particles entering Earth's space interact with the Earth's atmosphere.
