"Plumes" of outward flowing, hot gas in the Sun's atmosphere may be one source of the solar "wind" of charged particles. These images, taken March 7, 1996, by the Solar and Heliospheric Observatory (SOHO), show an ultraviolet image of the 1 million degree plumes and an ultraviolet image of the "quiet" solar atmosphere closer to the surface.
