They are cooler than the average surface temperature of the Sun.
Dark spots that appear on the surface of the sun are called sunspots. They are areas of reduced temperature caused by interactions with the sun's magnetic field.
Sunspots are dark spots visible on the sun that are caused by intense magnetic activity and causes the area where the sunspots are seen to cool the temperature at that area.
Sun spots.
sun spots are cooler parts of the sun
the sun spots like black little spots on the sun that explode every 11 years
Saturn may or may not have Saturn spots. Only the sun has sun spots.

Sun spots are not permanent, therefore it depends.
Sunspots are temporary areas on the sun's surface that appear darker than the surrounding areas due to their cooler temperature. They are not actual physical spots, but rather regions of intense magnetic activity that result in reduced surface temperature.
The black spots on the photosphere of the sun are called sunspots.
We call them sunspots, but dark and cool are relative terms. A sunspot is dark only relative to the surrounding solar surface, but still intensely bright compared to your common household light bulb. It's cooler than the surrounding solar material, but still hot enough to vaporize a spaceship and anyone inside it in a fraction of a second.
