It's because they're cooler.
Sunspots appear darker than their surroundings because they are cooler regions on the sun's surface, which causes them to emit less light and appear darker in comparison to the hotter surrounding areas.
Sunspots are cooler than the surrounding areas of the Sun's surface, or photosphere. While the photosphere has a temperature of about 5,500 degrees Celsius (9,932 degrees Fahrenheit), sunspots can have temperatures around 3,500 degrees Celsius (6,332 degrees Fahrenheit). This temperature difference is what makes sunspots appear darker than their hotter surroundings.
Sunspots are dark because they are cooler than the surrounding area on the Sun's surface, known as the photosphere. The magnetic fields near sunspots inhibit the flow of hot gases from below, causing them to be cooler and appear darker in comparison.
Sunspots are actually cooler regions on the sun's surface compared to their surroundings. They appear darker because they are areas of intense magnetic activity that disrupts the normal flow of heat to the surface.
magnetic activity on the sun's surface that appear darker than their surroundings due to their lower temperature. They are temporary phenomena that occur in cycles and can affect space weather on Earth.
Sunspots are areas on the sun's surface where magnetic activity inhibits convection, causing them to be cooler and appear darker than their surroundings. The connection between two sunspots is a shared magnetic field. Sunspots often appear in pairs or groups, with oppositely charged magnetic fields connecting them.
This is because they are cooler.
sunspots
Sunspots appear darker than their surroundings because they are cooler regions on the sun's surface, which causes them to emit less light and appear darker in comparison to the hotter surrounding areas.
Because just like in a fire Sunspots a cooler than the rest of the surface, and as in a fire the cooler spots appear darker.
Sunspots are cooler than the surrounding gases on the sun, which is why they appear darker in comparison. They are caused by fluctuations in the sun's magnetic field, leading to areas of reduced temperature.
Sunspots are about 1200 Kelvin colder than the surroundings.
Sunspots are cooler than the surrounding areas of the Sun's surface, or photosphere. While the photosphere has a temperature of about 5,500 degrees Celsius (9,932 degrees Fahrenheit), sunspots can have temperatures around 3,500 degrees Celsius (6,332 degrees Fahrenheit).

Sunspots are dark because they are cooler than the surrounding area on the Sun's surface, known as the photosphere. The magnetic fields near sunspots inhibit the flow of hot gases from below, causing them to be cooler and appear darker in comparison.
They are colder and darker than the other areas
Sunspots are actually cooler regions on the sun's surface compared to their surroundings. They appear darker because they are areas of intense magnetic activity that disrupts the normal flow of heat to the surface.
