On October 7, 2018, an astronaut aboard the International Space Station (ISS) took this photograph while orbiting at an altitude of over 400 kilometers above Australia.
tone orange which surrounds earth is known as nocturnal luminescence, diffused light strips extending from 75 to 600 kilometers into our atmosphere.
phenomenon This usually happens when molecules (mainly nitrogen and oxygen) are energized by ultraviolet (UV) radiation from sunlight. To release that energy, atoms in the lower atmosphere collide with each other and lose energy in collision. The result is a colorful glow.
nocturnal luminescence reveals some of the phenomena in the upper part of our atmosphere. It can help scientists learn about particle motion near the interface earth and space, including the links between space weather and the climate of the earth. Satellites offer a way to study this dynamic area.
The IONospheric Connection Explorer (ICON) satellite GODMOTHER, the launch of which is scheduled for November 8, will help scientists understand the physical processes at work where the atmosphere earth interact with the nearby space.
