Diagram of the Sun with a cutaway view of the interior showing the central core (white) where most of the fusion reactions take place. Circular arrows mark convection cells at various levels in the interior,the outermost of these cells produce the granular appearance of the sun. The figure also includes loop prominences & sunspots. The prominences,hot bright clouds of gas constrained by magnetic fields,appear as red,semi-circular features around the surface of the Sun. Sunspots are regions of cooler (hence comparatively dark) gas,often occurring in groups,that arise where a localised high magnetic field has suppressed the convection currents | |
