WebbThe photosphere is the lowest of the three layers that make up the Sun's atmosphere. Because the two upper layers are transparent to most of the wavelengths of visible light, the photosphere can be easily appreciated. We can not see beyond the bright gases of the photosphere, so that everything underneath it is considered the interior of the Sun. WebbThe Sun has an atmosphere composed of three main layers. The lowest one is the photosphere and essentially all of the visible light we see from the Sun comes from this thin layer of gas. The Sun's density at the photosphere is very low and we can see about 400 km into the photosphere.
