Sunspots are magnetic in nature. They are the places (active regions) where the Sun's magnetic field rises up from below the Sun's surface and those magnetic regions poke through. 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. The sunspots have lifetimes of days or perhaps one week or a few weeks. Here is one scenario that some scientists think explains how sunspots form.
