Wind as the Earth to evolve into planets like Venus. Additionally, planets with hotter lower atmospheres could accelerate the loss rate of hydrogen. Rather than air, the solar wind is a stream of charged particles—a plasma—ejected from the upper atmosphere of the sun at a rate of . 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, in part because of the high temperature of the corona, but also because of high kinetic energy
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
