Solar Wind

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The solar wind is a stream of charged particles ejected from the upper atmosphere of the sun. It consists mostly of electrons and protons with energies of about 1 keV. The stream of particles varies in temperature and speed with the passage of time. These particles are able to escape the sun''s gravity because of the high temperature of the corona and high kinetic energy of the particles. The solar wind creates the heliosphere, a vast bubble in the interstellar medium surrounding the solar system. Other phenomena include geomagnetic storms that can knock out power grids on Earth, the aurorae (northern lights) and the plasma tails of comets that always point away from the sun.
