Ton orange these envelopes earth known as night luminescenceLight bands extending from 75 to 600 kilometers in our atmosphere.
phenomenon Generally, molecules (mainly nitrogen and oxygen) occur when sunlight is emitted by ultraviolet (UV) radiation. To release this energy, the atoms in the sub-atmosphere collide and lose energy in the collision. The result is a colorful glow.
night luminescence reveals some phenomena of the upper reaches of the atmosphere. It can help scientists to learn about the motion of particles. earth The location, including links between space air and the earth's climate. Satellites offer a way to study this dynamic region.
IONospheric Connection Explorer (ICON) Satellite NASAScientists, scheduled for November 8th, will help scientists understand the physical processes in the working environment of the atmosphere. earth Interacts with the nearby area.
