Why do sunspots appear dark? The sunspots are large concentrations of strong magnetic field. This magnetic field partially blocks some energy from getting though the surface.
Sunspots are temporary spots on the Sun's surface that are darker than the surrounding area. They are regions of reduced surface temperature caused by concentrations of magnetic flux that inhibit convection. Sunspots appear within active regions, usually in pairs of opposite magnetic polarity. [2]
The reason sunspots appear so much darker than the rest of the sun's visible surface, or photosphere, is because they are much cooler, and the gas underneath a sunspot emits about...
Occasionally, dark spots freckle the face of the Sun. These are sunspots, cooler regions on the Sun caused by a concentration of magnetic field lines. Sunspots are the visible component of active regions, areas of intense and complex magnetic fields on the Sun that are the source of solar eruptions.
Sunspots initially give the impression of being dark, sculptured holes on the face of the sun. On the surface of the sun (called the photosphere), the temperature is around 11,000...
Sunspots are areas that appear dark on the surface of the Sun. They appear dark because they are cooler than other parts of the Sun’s surface. Solar flares are a sudden explosion of energy caused by tangling, crossing or reorganizing of magnetic field lines near sunspots.
Sunspots are dark regions on the Sun that are about the size of Earth. They are caused by strong magnetic fields that emerge through the photosphere, or surface, of the Sun.
