They are called sun spots, dark areas that are cooler than the rest of the surface.

Sunspots
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.
The dark spots on the Sun's surface are called Sunspots. These are formed by the sun's magnetic field because these areas have less convection underneath the sun's surface. Convection is how the sun's energy gets to the surface from the core in a circular motion. This reduces the heat in the area and makes the area appear darker than the surrounding sun. However, these spots are still extremely hot and can be many times the size of Earth!
