Video What is the real colour of Sun White or Yellow ?

The Sun appears yellow when observed from Earth. 

However, if you were to view the Sun from space, it would actually appear white. 

When we see it from Earth, it often looks yellow, orange, or red because of how its light scatters in our atmosphere, especially during sunrise or sunset. 

But if you were to observe the Sun from space, where there’s no atmosphere to filter its light, it would appear as a bright, pure white. 

This is because the Sun emits light across all visible wavelengths more or less equally, and when combined, that mix of colors gives us white light. 

This is because the Sun emits light across the entire spectrum, and in the absence of the Earth's atmosphere, all the colors combine to produce white light. 

The yellow color we see from Earth is due to the scattering of shorter wavelengths (like blue and violet) by the Earth's atmosphere, leaving the longer wavelengths (yellow and red) to dominate.

The Sun sported a whole slew of substantial sunspots over the past 11 days (July 1-10, 2014). 

This movie and still show the Sun in filtered white light speckled with more and larger sunspots than we have seen in quite some time. 

Sunspots are darker, cooler regions on the Sun created by intense magnetic fields poking through the surface. 

The Sun may have passed its peak level of activity, but it will still be producing many more sunspots and solar storms during the rest of this solar cycle.
