A sunspot can appear dark because it is cooler than the surrounding areas of the Sun's surface, with temperatures around 3,000 to 4,500 degrees Celsius compared to about 5,500 degrees Celsius for the Sun's photosphere. Although sunspots emit less light due to their lower temperature, they can still be bright in absolute terms when compared to other celestial objects. The contrast with the brighter, hotter surrounding regions makes them appear dark to our eyes.
