The ionosphere ( / aɪˈɒnəˌsfɪər /) [ 1][ 2] is the ionized part of the upper atmosphere of Earth, from about 48 km (30 mi) to 965 km (600 mi) above sea level, [ 3] a region that includes the thermosphere and parts of the mesosphere and exosphere. The ionosphere is ionized by solar radiation.
Dec 10, 2019 · NASA explores the unknown in air and space, innovates for the benefit of humanity, and inspires the world through discovery. Everything you need to know about the Ionosphere, the boundary between Earth's lower atmosphere — where we live and breathe — and the vacuum of space.
Aug 1, 2024 · 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.
The Ionosphere. Regions of the ionosphere, showing the D, E, and F layers. UCAR/Randy Russell. Earth's atmosphere contains a series of regions that have a relatively large number of electrically charged atoms and molecules. As a group, these regions are collectively called the ionosphere.
Apr 21, 2016 · There’s a strange glow in the night sky, and it’s coming from a dynamic layer of the atmosphere at the boundary between Earth and space—what scientists call the ionosphere. The layer extends from about 50 to 360 miles above the planet’s surface, and swells in response to incoming solar radiation.
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.
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...
Nov 7, 2017 · Learn about the features of the ionosphere! This little-explored region exists between space and Earth. It is home to the aurora, the international space station, a variety of satellites, and radio communication waves.
May 31, 2018 · Stretching from roughly 50 to 400 miles above Earth’s surface, the ionosphere is an electrified layer of the upper atmosphere, generated by extreme ultraviolet radiation from the Sun. It’s neither fully Earth nor space, and instead, reacts to both terrestrial weather below and solar energy streaming in from above, forming a complex space ...
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.
