Sun. Composite image of the Sun's visible surface (photosphere,orange) and its atmosphere (corona,purple/white). The corona can only be seen when the light from the photosphere is blocked,as happens during a total solar eclipse. The corona is a low density cloud of plasma (hot ions),and is formed into the patterns seen by the effect of the Sun's magnetic field. The corona is constantly losing mass in the form of the solar wind. On the surface of the Sun,sunspots are cooler regions that appear dark against their brighter,hotter surroundings. They are thought to be formed by magnetic field effects | |
