WEBApr 22, 2024 · The Short Answer: What are sunspots and solar flares? 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.

Sunspot - Wikipedia
WEBSunspots 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.

Sunspots | Center for Science Education
WEBSunspots are dark, planet-sized regions that appear on the surface of the Sun. They are caused by twisting, chaotic magnetic fields from within the Sun’s convective zone. These powerful magnetic disturbances produce active regions on the Sun, which can often create solar flares and coronal mass ejections (CMEs).

WEBSunspots are dark areas that become apparent at the Sun’s photosphere as a result of intense magnetic flux pushing up from further within the solar interior. Areas along this magnetic flux in the upper photosphere and chromosphere heat up, and usually become visible as faculae and plage – often times termed active regions.
What are Sunspots and What Causes Them? | High Point Scientific
WEBOct 4, 2023 · Author: Richard Bartlett. Views: 766. At some time or another, you’ve probably seen photos of the Sun with dark spots on its surface. These markings, known as sunspots, have been studied for hundreds of years, but what are they? What causes them? And is there a way to safely see them for yourself? What Are Sunspots?
