Caption: Sunspots, Solar Dynamics Observatory (SDO) footage. 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. The darkest regions (nearly vertical magnetic fields) are the umbras, surrounded by penumbras (bronze regions). The yellow background consists of convection cells called solar granules. The largest sunspots are larger than the Earth.
