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 ...

Short video featuring commentary by David Sibeck, project scientist for the THEMIS mission, discussing a visualization of reconnection fronts. A substorm , sometimes referred to as a magnetospheric substorm or an auroral substorm , is a brief disturbance in the Earth's magnetosphere that causes energy to be released from the " tail " of the ...
The plasmasphere, or inner magnetosphere, is a region of the Earth's magnetosphere consisting of low-energy (cool) plasma. It is located above the ionosphere . The outer boundary of the plasmasphere is known as the plasmapause , which is defined by an order of magnitude drop in plasma density.
The planet's magnetosphere, though small enough to fit within Earth, [97] is strong enough to trap solar wind plasma. This contributes to the space weathering of the planet's surface. [104] Observations taken by the Mariner 10 spacecraft detected this low energy plasma in the magnetosphere of the planet's nightside. Bursts of energetic ...

Magnetic pulsations are extremely low frequency disturbances in the Earth's magnetosphere driven by its interactions with the solar wind. [1] These variations in the planet's magnetic field can oscillate for multiple hours when a solar wind driving force strikes a resonance. [2] This is a form of Kelvin–Helmholtz instability. [1]
According to NASA, Earth's magnetosphere and the Sun's magnetic field are constantly pressed against one another on the dayside of Earth. Approximately every eight minutes, these fields briefly merge, forming a temporary "portal" between the Earth and the Sun through which high-energy particles such as solar wind can flow. The portal takes the ...
