PHOTO: An ISA astronaut captures the earth and wrapped in a mysterious orange light



An astronaut from the International Space Station took on October 7 an extra photo taken from an altitude of about 400 kilometers across Australia, which shows our planet in an orange color.

NASA scientists explained that the orange tan that surrounds the earth is known as antenna rail. The phenomenon is caused by chemical reactions in the planet's atmosphere, especially when certain molecules (mainly nitrogen and oxygen) are energy-induced by ultraviolet radiation of sunlight, according to the space agency's website. To release that energy, the atoms that are in the lower atmosphere collide with one another and lose energy in the collision, and the result is a colorful glow.

In addition to its spectacular and colorful representation, the phenomenon can also Give the researchers another knowledge of how the upper atmosphere works. For example, it may throw lucs on how particles move near the interface between ground and space, and also on how space and terrestrial weather connects, "said NASA.

Researchers have already used satellites like NASA's Ionospheric Connection Explorer (ICON) to study the dynamic zone.
