Sunspots are darker than the surrounding areas because they are expending less energy and have a lower temperature. Sunspots often have poles ("polarity") like the south and north poles of magnets. Sunspots are formed continuously as the Sun's magnetic field actively moves through the Sun. read more
Sunspots, temporary disturbances in the Sun's photosphere, are the most visible advertisement of the solar magnetic field. They appear dark because temperatures are considerably lower than in surrounding areas. Sunspots occur where the magnetic field lines emerge from the inside of the Sun to form expanding loops above its surface. read more
Sunspots appear as dark marks, because they release less energy and have a lower temperature than surrounding regions. The darkest region at the center of the sunspot is called the umbra. The penumbra surrounds the umbra and has a lighter color. The average temperature of sunspots is 2240.3 degrees Fahrenheit. read more
