NASA WEB-Vivid orange streamers of super-hot, electrically charged gas (plasma) arc from the surface of the Sun and reveal the structure of the solar magnetic field rising vertically from a sunspot. Astronomers are now studying the magnetic fields on solar-type stars using techniques of polarimetry.
