Sunspot

Real World Example

Imagine hosting a party where one room feels cooler than the others because the heater isn't working properly. Just like that cooler room, a sunspot on the Sun appears darker because it's not as hot as the surrounding areas. In this analogy, the cooler room represents the sunspot, the party is the Sun's surface, and the broken heater is like the magnetic field that reduces the temperature, making the sunspot stand out as darker amidst the brighter, hotter surroundings.
