SOLAR SYSTEM

Detailed explanation-1: -Sunspots are areas that appear dark on the surface of the Sun. They appear dark because they are cooler than other parts of the Sun’s surface.

Detailed explanation-2: -Sunspots appear dark because they are cooler than their surroundings. Large sunspots are thousands of degrees cooler than the areas that surround them (about 4, 200 °C for a sunspot compared to 6, 000 °C for the photosphere surrounding it). Sunspots are only dark in contrast to the bright face of the Sun.

Detailed explanation-3: -As well as being a darker area on the sun, a sunspot is an area that temporarily has a concentrated magnetic field. This magnetic force inhibits the convective motion, which ordinarily brings hot matter up from the interior of the sun, so the area of the sunspot is cooler than the surrounding plasma and gas.

Detailed explanation-4: -Sunspots are dark blotches on the Sun in which magnetic forces are very strong, and these forces block the hot solar plasma, and as a result sunspots are cooler and darker than their surroundings.
