Solar convection. Computer illustration of a section of the Sun's interior,showing the convective regions in the photosphere which give the Sun's surface its granulated appearance. The photosphere is the Sun's outer layer from which it seems to emit light. The movement of rising hot gases and sinking cooler gases is shown by the arrows,with the cells becoming smaller nearer the edge of the Sun. At the surface,the areas of rising gas are seen to be hotter and brighter (yellow) than those where the cool gas begins to sink (brown). A large dark sunspot is seen at lower left. Sunspots are cooler areas of the Sun's surface stabilised by a strong magnetic field | |
