From NASA Heliophysics. The number of sunspots increases and decreases over time in a regular, approximately 11-year cycle, called the sunspot cycle. The exact length of the cycle can vary. It has been as short as eight years and as long as fourteen, but the number of sunspots always incre

Sun Spots mark areas where light is trapped. Powerful electromagnetic forces interrupt the convective motion that brings hot, inner materials to the sun's surface. The largest sunspots can be over 10 times the size of Earth. | http://science.discovery.com/tv-shows/how-the-universe-works/
