mag•ne•to•sphere

(mægˈni təˌsfɪər)

n.

1. the outer region of the earth's ionosphere where the earth's magnetic field controls the motion of charged particles, as in the Van Allen belts.

2. such a region of another planet.

[1959]

mag•ne`to•spher′ic (-ˈsfɛr ɪk) adj.

magnetosphere

The region near the planet possessing a magnetic field, which determines the motion of the charged particles in this region. Earth, Saturn, Jupiter, Uranus, and Mercury are the solar system planets known to have magnetospheres.

ThesaurusAntonymsRelated WordsSynonymsLegend:

Noun

magnetosphere - the magnetic field of a planet; the volume around the planet in which charged particles are subject more to the planet's magnetic field than to the solar magnetic field

magnetic field, magnetic flux, flux - the lines of force surrounding a permanent magnet or a moving charged particle

Uni Memorial Lecture speaker revealed

Auroras are produced by glowing oxygen and nitrogen atoms in Earth's upper atmosphere, excited by charged particles streaming in from the near-Earth magnetic environment called the magnetosphere. Scientists didn't know if STEVE was a kind of aurora, but a 2018 study found its glow is not due to charged particles raining down into Earth's upper atmosphere.

It was the first satellite dedicated to observing the magnetosphere of the Earth and producing global images of plasma in the inner magnetosphere.

Space scientists at US universities and national laboratories explore conditions on the Sun and in the solar wind, magnetosphere, ionosphere, and thermosphere that can influence the performance and reliability of space-born and ground-based technological systems, and can endanger human life or health.

Juno is the first mission dedicated to the study of the planet's interior to learn more about its origins, structure, atmosphere and magnetosphere. Aerojet Rocketdyne provided 26 propulsion devices and six pressurant tanks aboard the United Launch Alliance (ULA) Atlas V rocket during its 2011 launch, as well as 12 propulsion devices on the spacecraft during its five-year journey through space.
