For this reason, Earth looks orange in this photo

On October 7, 2018, an astronaut aboard the International Space Station (ISS) took this photograph while orbiting at an altitude of more than 400 kilometers above Australia.

The tone orange which involves the Earth It is known as night luminescencediffuse bands of light that extend from 75 to 600 kilometers in our atmosphere.

O phenomenon It usually occurs when molecules (mainly nitrogen and oxygen) are energized by ultraviolet (UV) radiation from sunlight. To release this energy, the atoms in the lower atmosphere collide with each other and lose energy in the collision. The result is a colorful glow.

O night luminescence reveals some of the phenomena of the upper reaches of our atmosphere. It can help scientists learn about the movement of particles near the interface of the Earth and space, including connections between space weather and Earth's climate. Satellites offer a way to study this dynamic zone.

The IONospheric Connection Explorer (ICON) satellite, NASA, whose launch is scheduled for November 8, will help scientists understand the physical processes at work, where the atmosphere of the Earth interacts with the next space.
