Webb5 mars 2024 · The sunspots are caused by the sun's magnetic fields. The photosphere is one of the most visible layers of the sun from the surface of the earth. There is a temperature of around 10,000 °F (5,538 °C) in this area. Light and heat are sent to Earth through this layer, which resembles a bright disc. Webb11 aug. 2014 · The photosphere is the visible surface of the Sun that we are most familiar with.
