Webb1 nov. 2024 · Abstract The Sun is often racked by short-term violent events such as flares and coronal mass ejections (CMEs) but these two phenomena are often confused. Both are caused by the release of energy due to the reconnection of stressed and unstable magnetic fields. Flares bathe the solar system in electromagnetic radiation from gamma rays to … Webb25 maj 2024 · The visible surface of the sun, or the photosphere, is around 6,000°C.

WebbThe temperature in the chromosphere rises from 6000 K to about 20,000 K, making it hotter than the photosphere but not as hot as the higher atmosphere, the corona. This base layer of the sun's atmosphere requires more energy to heat than the million degree corona itself and provides all the material to the corona and heliosphere.
