Solar wind Solar wind The solar wind is a stream of charged particles released from the upper atmosphere of the Sun, called the corona. This plasma consists of mostly electrons, protons and alpha particles with kinetic energy between 0.5 and 10 keV. Embedded within the solar-wind plasma is the interplanetary magnetic field. The solar wind varies in density, temperature and speed over time and over solar latitude and longitude. Its particles can escape the Sun's gravity because of their high energy resulting from the high temperature of the corona, which in turn is a result of the coronal magnetic field. At a
Sun Stream Stakes, Britain's most prestigious race for two-year-old fillies. In a closely contested three-way finish she was beaten into third place by Sweet Cygnet and Neola. She was regarded as one of the best juvenile fillies to race in Britain in 1944. Sun Stream began her three-year-old season in the seven furlong Upwell Stakes, a now discontinued race which served as a trial for the 1000 Guineas, in which she finished second to Exotic. Two weeks later, on VE Day, Sun Stream started 5/2 favourite for the 1000 Guineas which, because of the war, was moved from its traditional venue on
