Ionosphere - Wikipedia
The ionosphere is a shell of electrons and electrically charged atoms and molecules that surrounds the Earth, [16] stretching from a height of about 50 km (30 mi) to more than 1,000 km (600 mi). It exists primarily due to ultraviolet radiation from the Sun.
10 Things to Know About the Ionosphere - NASA Science
Dec 10, 2019 · The ionosphere stretches roughly 50 to 400 miles above Earth's surface, right at the edge of space. Along with the neutral upper atmosphere, the ionosphere forms the boundary between Earth's lower atmosphere — where we live and breathe — and the vacuum of space.
The Ionosphere | Center for Science Education
Regions with higher concentrations of ions and free electrons occur at several different altitudes and are known, as a group, as the ionosphere. There are three main regions of the ionosphere, called the D layer, the E layer, and the F layer.
Ionosphere | NASA Space Place – NASA Science for Kids
Aug 5, 2024 · What is the ionosphere? The ionosphere is a very active part of the atmosphere, and it grows and shrinks depending on the energy it absorbs from the Sun. The name ionosphere comes from the fact that gases in these layers are excited by solar radiation to form ions, which have an electrical charge.
ionosphere and magnetosphere - Encyclopedia Britannica
Ionosphere and magnetosphere, regions of Earth’s atmosphere in which the number of electrically charged particles—ions and electrons—are large enough to affect the propagation of radio waves. The charged particles are created by the action of extraterrestrial radiation (mainly from the Sun) on.
What is the ionosphere? (And who is Steve?) | Space
Feb 8, 2021 · A dense layer of molecules and electrically charged particles, called the ionosphere, hangs in the Earth's upper atmosphere starting at about 35 miles (60 kilometers) above the planet's surface...
Ionosphere | NOAA / NWS Space Weather Prediction Center
The Ionosphere is part of Earth’s upper atmosphere, between 80 and about 600 km where Extreme UltraViolet (EUV) and x-ray solar radiation ionizes the atoms and molecules thus creating a layer of electrons.
Revolutions in Understanding the Ionosphere, Earth’s Interface ... - NASA
Dec 14, 2016 · Scientists from NASA and three universities have presented new discoveries about the way heat and energy move and manifest in the ionosphere, a region of Earth’s atmosphere that reacts to changes from both space above and Earth below.

Plasma - Ionosphere, Upper Atmosphere, Electrons | Britannica
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.
