Sunspots and convection cells on Sun's surface, illustration. Sunspots are areas of magnetic activity that are cooler than the rest of the Sun's surface. They range in size from hundreds to thousands of kilometres across. Sunspots form where magnetic field lines (one shown here) become twisted and entangled. The red arrows mark convection cells called solar granules, each around 1000 kilometres across.
