  1. Aug 1, 2024 · Learn about the ionosphere, a part of the atmosphere where gases are excited by solar radiation to form ions. Find out how the ionosphere affects auroras, Earth's magnetic field, and space weather.

  2. Jul 23, 2024 · Plasma - Ionosphere, Upper Atmosphere, Electrons: At altitudes below about 2,000 kilometres, the plasma is referred to as the ionosphere. Thousands of rocket probes have helped chart the vertical structure of this region of the atmosphere, and numerous satellites have provided latitudinal and longitudinal information.
