The photosphere is the lowest layer of the sun's atmosphere — the innermost layer we can observe directly. The term photosphere means "sphere of light" and is the layer where most of the sun's energy is emitted. It takes about eight minutes for sunlight from the photosphere to reach Earth. The temperature of … Visa mer The layer above the photosphere is the chromosphere. The chromosphere emits a reddish glow as super-heated hydrogen burns off. But the red rim can only be seen during a total solar eclipse. At other times, light from the … Visa mer The third layer of the sun's atmosphere is the corona.
