Sunspots are patches on the Sun's surface that look dark because they are cooler than the surrounding areas. They are associated with magnetic activity and can vary in size and number over time, typically appearing in cycles. Despite their name, sunspots are still quite hot compared to other celestial objects, but they appear darker than the hotter regions of the Sun's surface due to their lower temperature.
