They are called sunspots. They are only "dark" in comparison to the brilliance of the rest of the Sun.
Sunspots sit on the sun's photosphere. The photosphere is the surface of the sun, and sunspots are dark regions on it that are visible. The photosphere's average temperature is about 5800 degrees Kelvin.
The name of the sun's surface layer is called the chromosphere. The other layers of the sun is called photosphere and convection zone.
The darkest part, where the magnetic field is approximately vertical to the sun's surface is called the Umbra.

Photosphere
Sunspots are the temporary dark spots on the surface of the sun, specifically the photosphere. Sunspots can get as big as 50,000 km long. Sunspots can interrupt terrestrial magnetism.
