  2. Ionosphere - Wikipedia

    en.wikipedia.org/wiki/Ionosphere

    Geomagnetic storms and ionospheric storms are temporary and intense disturbances of the Earth's magnetosphere and ionosphere. During a geomagnetic storm the F₂ layer will become unstable, fragment, and may even disappear completely. In the Northern and Southern polar regions of the Earth aurorae will be observable in the night sky.

  3. Stellar magnetic field - Wikipedia

    en.wikipedia.org/wiki/Stellar_magnetic_field

    The magnetosphere contains charged particles that are trapped from the stellar wind, which then move along these field lines. As the star rotates, the magnetosphere rotates with it, dragging along the charged particles. [13] As stars emit matter with a stellar wind from the photosphere, the magnetosphere creates a torque on the ejected matter.

  4. Magnetosphere - Wikipedia

    en.wikipedia.org/wiki/Magnetosphere

    The magnetosphere of Jupiter is the largest planetary magnetosphere in the Solar System, extending up to 7,000,000 kilometers (4,300,000 mi) on the dayside and almost to the orbit of Saturn on the nightside. [17] Jupiter's magnetosphere is stronger than Earth's by an order of magnitude, and its magnetic moment is approximately 18,000 times ...

    The ionosphere is an ideal place to look for the telltale signs of this particular form of dark matter, the scientists explain, because we already spend a lot of time and resources doing studies ...

  7. Heliophysics - Wikipedia

    en.wikipedia.org/wiki/Heliophysics

    Determine changes in the Earth's magnetosphere, ionosphere, and upper atmosphere in order to enable specification, prediction, and mitigation of their effects. Heliophysics seeks to develop an understanding of the response of the near-Earth plasma regions to space weather .

    Where and when you can see Jupiter in the sky. Jupiter is expected to go into opposition on Dec. 7, according to EarthSky.org.. Around sunset, look close to overhead -- but not directly -- to see ...

  9. Space weather - Wikipedia

    en.wikipedia.org/wiki/Space_weather

    Since the solar wind carries disturbances that affect the magnetosphere and ionosphere, IMP-8 demonstrated the utility of continuous solar wind monitoring. IMP-8 was followed by ISEE-3 , which was placed near the L 1 Sun-Earth Lagrangian point , 235 Earth radii above the surface (about 1.5 million km, or 924,000 miles) and continuously ...
