Why Do Sunspots Appear Dark In Pictures Of The Sun
Olivia Luz
They are holes in the solar surface through which we can see through to deeper darker layers of the sun.
They actually are fairly bright but appear dark against the even brighter background of the surrounding photosphere. Fusion reactions in the sun have ceased. Sunspots usually appear in pairs of opposite magnetic polarity. Due to some magnetic field action convection currents are less there and so temperature is low so we see it as drk.
Sunspots appear dark because they are cooler than the rest of the surface of the sun but they are actually extremely bright. This causes the skin tone to appear uneven or discolored. Sunspots are temporary phenomena on the sun s photosphere that appear as spots darker than the surrounding areas. Why do sunspots appear dark in pictures of the sun.
They are irregularly shaped and tend to appear in clusters or groups always within five to 35 degrees north and south of the sun s equator. Sun spots have been studied for about the last two hundred plus. A they are holes in the solar surface through which we can see to deeper darker layers of the sun. They appear dark because they are cooler than other parts of the sun s surface.

These magnetic fields are so strong that they keep some of the heat within the sun from reaching the surface. The temperature of a sunspot is still very hot though around 6 500 degrees fahrenheit. In this image you can see an active region on the sun with dark sunspots. The reason a sunspot appears dark is that the gas inside the spot where the magnetic field is strongest is only emitting about 1 4 as much light as from the rest of the solar surface.
It s because they form at areas where magnetic fields are particularly strong. They are regions of reduced surface temperature caused by concentrations of magnetic field flux that inhibit convection. Why do sunspots appear dark in pictures of the sun.
