MAGNETOSPHERE
| Pronunciation (US): |  | (GB): | |
I. (noun)
Sense 1
Meaning:
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
Classified under:
Nouns denoting natural phenomena
Hypernyms ("magnetosphere" is a kind of...):
flux; magnetic field; magnetic flux (the lines of force surrounding a permanent magnet or a moving charged particle)
Context examples:
Its magnetic field axis points 60 degrees away from that spin axis, so as the planet spins, its magnetosphere - the space carved out by its magnetic field - wobbles like a poorly thrown football.
(The ice giant Uranus appears to be losing a bit of its atmosphere to space, NASA)
Typically, magnetospheres are shaped by the pressure of supersonic solar wind particles flowing past them.

A better understanding of the magnetosphere could provide detailed information about how Earth and other planets interact with the space environment.

Coming face-to-face with the gas giant, Juno will begin to unravel some of the greatest mysteries surrounding our solar system's largest planet, including the origin of its massive magnetosphere.

On Earth, auroras are created when charged particles from the solar wind enter our planet's magnetosphere, a region where Earth's magnetic field accelerates and sends them toward the poles.

Measurements of the massive planet’s magnetosphere, from Juno’s magnetometer investigation (MAG), indicate that Jupiter’s magnetic field is even stronger than models expected, and more irregular in shape.
(First Science Results from NASA’s Juno Mission, NASA)
Nestled there, it’s protected from the solar wind, making its shape different from other magnetospheres in the solar system.

The waves, called electromagnetic ion cyclotron (EMIC) waves, reveal the temperature and density of plasma particles in the magnetosphere.

If it were visible in the night sky, Jupiter's magnetosphere would appear to be about the same size as Earth's full moon.
(Juno Peers Inside a Giant, NASA)
While most planets in our solar system, including Earth, have magnetic environments — known as magnetospheres — no one expected a moon to have one.
