When an area of the sun's gases is cooler than the surrounding gases, the phenomenon known as sunspots becomes visible. Sunspots are dark areas on the surface of the sun caused by magnetic activity. These regions have a lower temperature compared to the surrounding gases, making them appear darker and cooler. Sunspots can vary in size and can last from a few days to several weeks. They are often accompanied by other solar phenomena such as solar flares and prominences, which are also related to intense magnetic activity on the sun's surface. However, of the options provided, sunspots are the specific feature that becomes visible when there is a contrast in temperature on the sun's surface.
