A sunspot is a dark spot on the surface of the Sun. The cause of these spots is magnetic phenomena that reduces the temperature of the Sun's surface. The largest sunspots are visible from Earth without a telescope, but they are certainly not viewable by merely looking at the son.

A sunspot is an area on the Sun that is abnormally cooler than its surroundings. As a result, it appears darker than the surrounding areas. Sunspots are also frequent places for solar flares to happen. For more information, search it up on Wikipedia.
