The Solar Wind (Artist's conception)
Solar Wind

The Solar Wind is the name given to the consant stream of particles emitted by the explosions that fuel the sun. The density of the solar wind varies depending on the level of solar activity at any given time. As the solar wind nears the Earth, it first hits the Earth's Magnetosphere. The particles of the solar wind are charged because they are in the Plasma state; so, they are attracted to the magnetic lines of the magnetosphere. These lines travel around the Earth, and come down sharply at the poles. When the particles come down to the Earth's poles, they can cause radio interference and problems with power grids. One of the more beautiful results of the solar wind is the Auroras.
