    Earth’s Magnetosphere and Plasmasheet

    The Earth, surrounded by lines shooting out in many directions. They are labeled Interplanetary Magnetic Field Lines, which flow toward Earth. A bend in on of those lines is a Bow Shock. Lines looping out from Earth are labeled magnetosheath, magnetopause, magnetotail. Shaded areas billowing out from Earth are the Plasmasphere, Radiation Belts, and Plasma Sheet.

    A magnetosphere is that area of space, around a planet, that is controlled by the planet's magnetic field. The shape of the Earth's magnetosphere is the direct result of being blasted by solar wind. The solar wind compresses its sunward side to a distance of only 6 to 10 times the radius of the Earth. …

    The Sun, with layers labeled: Core, radiative zone, Convection zone, chromosphere, and corona. Features, including a solar prominent, subsurface flows, sunspots, flare, and a corona hole are labeled.

    The Sun and its atmosphere consist of several zones or layers. From the inside out, the solar interior consists of: The Core – the central region where nuclear reactions consume hydrogen to form helium. These reactions release the energy that ultimately leaves the surface as visible light. The Radiative Zone – extends outward from the …
