NASA’s heliophysics researches the ionosphere-thermosphere-mesosphere region where our neutral atmosphere transitions into the ionized plasma of space. In this thin shell that surrounds our home planet, the atmosphere is in constant motion, shaped by the influence of both solar activity and changes in the lower atmosphere and in near-Earth space.

13 Μαΐ 2019 · The ionosphere and thermosphere (IT) constitutes a coupled, complex and dynamical electromagnetic and photochemical system, which is sensitive to a combination of external factors: particle precipitation and electrical currents from the Earth's magnetosphere and incoming solar radiation produce dramatic effects in the IT and significantly alter ...
The ionosphere (/ aɪ ˈ ɒ n ə ˌ s f ɪər /) [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.
Thermosphere and Ionosphere Definitions. Thermosphere: neutrals. Layers are divided based on temperature gradient. Starting from the coldest region at mesopause to several hundred km. Ionosphere: plasma. Layers are divided based on plasma density. Starting from about 80 km to several hundred km. Thermosphere and Ionosphere Density Profiles.
10 Δεκ 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.
14 Δεκ 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.
Earth's atmosphere is composed of a series of layers, each with its own specific traits. Moving upward from ground level, these layers are called the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. The exosphere gradually fades away into the realm of interplanetary space.
