Sunspots are areas on the sun's photosphere which appear black in telescopes. In actuality, they are bright but are cooler than the surrounding photosphere and so appear darker.

They are magnetic storms on the surface of the sun, and the hot plasma is shunted towards either the negative or positive poles, thereby creating a 'cool spot' on the photosphere. These storms have an 11-year cycle which has yet to be well understood.
