Astronaut from the International Space Station took an extraordinary photo on October 7, taken from the height of the eye 400 kilometers across Australia, which shows our planet in orange color.
NASA scientists have explained that the orange color surrounding the Earth is known as air glow, The phenomenon is caused by chemical reactions in the atmosphere of the planet, especially when it is determined molecules (mainly nitrogen and oxygen) energized by ultraviolet radiation sunlight, according to the space agency website. To free this energy, the atoms present in the lower atmosphere collide with each other and lose energy in collision, resulting in a colorful glow.
Behind his spectacular and colorful representations, such a phenomenon could have been to provide scientists with knowledge of the functioning of the upper atmosphereFor example, a port can be thrown in the way particles move near the interface between Earth and Space, and even how to connect space and Earth weather, NASA says.
Researchers have already used satellites such as NASA's Ionospheric Connection Explorer (ICON) to study this dynamic zone.
