They are cooler than the surrounding surface of the sun.
Relatively cool to the surrounding erea.
Cooler than the average surface.
Because the sunspots are cooler spots on the sun. They are much different from the rest of the sun so the appear really dark.
In regular photographs, sunspots appear dark because the temperature of surrounding areas is so high that by comparison, sunspots are cool. In reality, they are still immensely hot.

Sunspots
Sunspots appear because of the magnetic fields, they appear black because they're slightly cooler than the surface of the rest of star.
Even though sunspots are fiery white hot, they are somewhat cooler than the part of the Sun around them. When you inspect the Sun through a very dark filter (The only safe way) the Sun itself does not look very bright, and sunspots appear dark in comparison.
A sunspot is a region on the Sun's photosphere that is cooler and darker than the surrounding material. Sunspots often appear in pairs or groups with specific magnetic polarities that indicate electromagnetic origins.
The sun spots are the cooler spots. They are darker because there isnt much heat compared to the rest of the sun
they may seem dark because there surroundings are cooler than the sun
Sunspots appear darker because they are "cooler" than the surrounding area.
Sunspots give off magnetic rays that affect terrestrial life. Then are just dark patches on the sun's surface that appear periodically. They are not as hot as other parts on the sun though.
This is because they are cooler.
