They are cooler than the surrounding surface of the sun.
Because the sunspots are cooler spots on the sun. They are much different from the rest of the sun so the appear really dark.
Sunspots appear dark in color because they are cooler than the surrounding areas on the Sun's surface, which are much hotter. The cooler temperature of sunspots is due to magnetic activity inhibiting the flow of heat from deeper within the Sun.
Sunspots
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.
Even though sunspots are fiery white hot, they are somewhat cooler than the part of the Sun around them. When you inspect the Sun through a very dark filter (The only safe way) the Sun itself does not look very bright, and sunspots appear dark in comparison.
Dark spots that appear on the surface of the sun are called sunspots. They are areas of reduced temperature caused by interactions with the sun's magnetic field.
Sunspots appear because of the magnetic fields, they appear black because they're slightly cooler than the surface of the rest of star.
Dark areas on the photosphere of the Sun are called sunspots. They appear dark because they are cooler regions compared to their surrounding areas, which results in decreased luminosity. Sunspots are temporary phenomena that occur in 11-year cycles as part of the Sun's magnetic activity.
Sunspots are the temporary dark spots on the surface of the sun, specifically the photosphere. Sunspots can get as big as 50,000 km long. Sunspots can interrupt terrestrial magnetism.
Sunspots appear dark in color because they are areas on the Sun's surface that are cooler compared to the surrounding areas. This temperature difference causes them to appear darker when observed against the hotter background of the Sun.
The sun spots are the cooler spots. They are darker because there isnt much heat compared to the rest of the sun
A sunspot is a region on the Sun's photosphere that is cooler and darker than the surrounding material. Sunspots often appear in pairs or groups with specific magnetic polarities that indicate electromagnetic origins.
