"The Sun Is Actually White": Ex NASA Astronaut Confirms Space Fact

The real colour of the Sun is actually white and the reason the dwarf star generally looks yellow is because of a strange play of physics of light which makes the sun appear yellow utmost of the time. 

 

 For those who suppose that the Sun is actually yellow, that isn't its true colour. And on Tuesday, former NASA astronaut Scott Kelly verified this space fact. 

 The real colour of the Sun is actually white and the reason the dwarf star generally looks yellow is because of a strange play of physics of light which makes the sun appear yellow maximum of the time. The sun is basically all colours mixed together, which appear to our eyes as white. But this is only easy to see in filmmaking taken from space. 

 The sun appears yellow due to our atmosphere. But once you leave the Earth's atmosphere, the Sun appears white rather than any single colour. This is due to how our eyes see colour. 

 

 We're incapable to perceive a singular colour of the sun because the quantity of sun simply saturates the photoreceptor cells in our eyes, causing all the colours to be mushed together. When every colour of light is combined, you end up with white. therefore, the sun appears yellow on Earth and white in space. 

 On Earth, the atmosphere also plays a part in the colour of the Sun. According to NASA, since shorter wavelength blue light is scattered more efficiently than longer wavelength red light, we lose some of the blue shades of the sun as sun passes through the atmosphere. In addition, all wavelengths of visible light passing through our atmosphere are downgraded so that the light that reaches our eyes doesn't incontinently saturate the cone receptors. 

This allows the brain to perceive colour from the image with a little lower blue-yellow. Though it doesn't affect what our eyes see, allx-ray and gamma- shaft radiation is filtered out before it comes near to the ground. utmost UV is absorbed by stratospheric ozone( above 10 km) and utmost IR is absorbed by water vapour and other molecules withnon-zero dipole moments," the US space agency explained.

 Additional, it also added that when the sun passes through a lot of atmospheres as is the case of sunrises and evenings, indeed more, blue light is scattered and a much lesser chance of the longest wavelength( red) light makes it to our eyes.
