Auroras' lengths probably relate to activity in the magnetosphere
, and smaller magnetic waves might energize particles to create the narrower (1-km-wide) curtains.
The exact position of this shock front changed over time: at times of intense solar activity, Saturn's magnetosphere
tended to become compressed and so the shock front moved inwards, but at times when the solar wind was weaker, its magnetosphere
tended to expand outwards.
In order to investigate the degree to which results from one set of experiments or observations are actually applicable to other environments, researchers in magnetospheric physics, solar physics, and astrophysics consider the significance of findings about particle acceleration in the laboratory, in Earth's magnetosphere
, in the solar wind, at the Sun, and beyond in the astrophysical plasma.
Auroras, such as Earth's northern lights, arise when charged particles from space strike a planet's magnetosphere
, the bubble-shaped region defined by a planet's magnetic field.
And this fall, the sun's peaking 11-year activity cycle will shower aurora borealis, or northern lights, over the Northern Hemisphere: "Sky Show" provides a great hook to interest students in "solar max" and Earth's magnetosphere
Terrestrial aurorae are produced when charged particles, known as coronal mass ejections (CMEs), enter Earth's magnetosphere
- a region of space formed by the interaction between stellar winds and the planet's magnetic field.
Open Competition: Creating a small spacecraft to study the interaction of waves and particles at the external borders of the Earth's magnetosphere
and the solar wind interaction with the magnetosphere
(Code MF OCD: "Resonance" (resonance-ICA))
Over the next few days, this solar wind is likely to impact Earth's magnetosphere
and possibly cause displays of aurora.
5 ( ANI ): Researchers have been left searching for potential plasma loss mechanisms from Saturn's magnetosphere
For example, during the 8- to 12V2-day Apollo missions, Earth's magnetosphere
provided the astronauts a modicum of protection from space radiation.
After a brief historical review of early ring current studies, 32 papers on the physics and structures of the earth's inner magnetosphere
are organized into sections that deal with the sources and losses of plasma and energetic particles in the inner magnetosphere
, energetic particle acceleration mechanisms, external driving mechanisms of the inner magnetosphere
, observational aspects of inner magnetosphere
dynamics, and large-scale modeling efforts of the inner magnetosphere
