In a white light photo, the part of the Sun that we see is called the photosphere. It has a temperature of about 6000 degrees Celsius, much cooler than the corona. Sometimes there are notable dark spots.These sunspots come and go, so look at the Sun again in a few days to see how its appearance has changed.n a white light photo, the part of the Sun that we see is called the photosphere.

Take away concepts. 1  The sun emits mostly visible light. 2  Visible light, or the colors that we see are parts of the electromagnetic radiation spectrum. 3  The Earth emits mostly longer wavelength infrared radiation that we cannot see. Sunlight made up of visible light passes through the atmosphere on the way into Earth, but the greenhouse gases in the Earth's atmosphere absorb infrared radiation going out to space.
