A sunspot is a temporary phenomenon on the Sun's photosphere that appears as a spot darker than its surroundings. Sunspots are caused by the Sun's magnetic field becoming concentrated in certain areas, which reduces the energy flow from the interior of the Sun to its surface. Consequently, these areas are cooler than the rest of the Sun's surface, resulting in their darker appearance. Sunspots typically occur in pairs or groups and vary in size and lifespan.
