As it grows, it can develop a distinct structure with a dark umbra and a lighter penumbra. This magnetic energy is generated by the motion of charged particles in the plasma.
Magnetic Fields and Sunspots in the Photosphere
This layer has a temperature of approximately 5,500 degrees Celsius at its base, cooling as it extends outward. Sunspots often appear in pairs or groups, corresponding to the north and south magnetic poles.
Sunspots are among the most visually striking features on the solar surface, appearing as dark blemishes that traverse the bright disk of the Sun. A sunspot typically begins as a small, intense magnetic flux tube.
Magnetic Fields and Sunspots in the Photosphere
This stark temperature difference is why sunspots appear dark; they are dimmer and emit less visible light compared to the hotter, brighter photosphere. The core is the central region where nuclear fusion occurs, but this is not where sunspots are found.
More About What layer of the sun do sunspots occur
Looking at What layer of the sun do sunspots occur from another angle can help expand the discussion and give readers a second clear paragraph under the same section.
More perspective on What layer of the sun do sunspots occur can make the topic easier to follow by connecting earlier points with a few simple takeaways.
