Extreme UV and X-rays are produced (left of wavelength range) but comprise very small amounts of theSun'stotal output power (area under the curve). Spectral distribution of sunlight. The different curves reflect 3 different equally valid ways of characterizing the same sunlight.
Thecolorof thesunreveals a range of information about our star including the stages of its life and how it interacts with the atmosphere of Earth. Color, though, is how our brain interprets the full mix of light wavelengths entering our eyes. Thesun'speak intensity is at a green wavelength.
But green is just one of manycolorsof light thesunemits. Sunlight spans the whole light spectrum — from long-wavelength radio waves to short-wavelength X-rays. Learn whatcolortheSunis and why it appears differentcolorsfrom Space, the Earth, and in photographs.
TheSungives off light that has even more energy than purple. One type of this light is called ultraviolet (UV) and it can give you a sunburn. Another type of light with a lot of energy are X-rays, just like you get when you go to the dentist.
X-rays are light too! We just can't see them. TheSunwould have to emit only green light for our eyes to perceive it as green. This means the actual colour of theSunis white.
So, why does it generally look yellow? This is because the Earth's atmosphere scatters blue light more efficiently than red light. Thesun'srayswarm the blackened ring more than they do the whitened one, and this temperature difference produces an electromotive force that is nearly proportional to the sunlight's intensity. The electromotive force is automatically measured and recorded and yields a continuous record of the duration and intensity of the periods of ...
TheSunis a different colour depending on how you observe it. These three images are, from left, NASA's NuSTAR seeing high-energy X-rays; the Japanese Aerospace Exploration Agency's Hinode mission seeing lower energy X-rays; and NASA's Solar Dynamics Observatory seeing ultraviolet light. Thecolorof thesunis dependent on a number of factors, such as thesun'ssurface temperature, Earth's atmosphere, and how the human eye seescolor.
The'colorof thesun'is the spectrum ofcolorspresent in sunlight, which arises from a complex interplay of all parts of thesun.
