All about Sunspots
Sunspots are cooler, darker patches on the surface of the Sun. They are caused by strong magnetic activity that stops heat from rising. Sunspots come and go in cycles that last about 11 years.
Sunspots can be many times larger than Earth. Large sunspots are often linked to solar flares and bursts of charged particles, which can affect satellites and radio signals.
