Most people believe the Sun is yellow since it appears yellow from the ground, but after reading this tweet, we may have to rethink our views.
This space truth was recently confirmed by NASA astronaut Scott Kelly in a widely shared tweet. The Sun's true colour is actually white, and the explanation the dwarf star typically seems yellow is due to an odd interaction between light physics that causes the sun to look yellow the majority of the time.
Our atmosphere causes the sun to appear yellow. But once you are outside of the atmosphere of the Earth, the Sun appears to be all white. NASA claims that this is because of way our eyes see colour.
Sunsets and sunrises seem red, yellow, or orange because the sun's light must traverse through all of Earth's atmosphere to reach the surface when it is lower in the sky than when it is directly overhead.
According to NASA, shorter light wavelengths, like blue, are more likely to be scattered through the atmosphere as time goes on, whereas longer light wavelengths, like red, can go considerably farther.
Since the amount of sunshine merely inundates the photoreceptor cells in our eyes, blending all the colours together, we are unable to distinguish a single colour from the sun. White is the result of combining all colours of light. As a result, the sun appears white in space and yellow on Earth. DailyBangladesh/RAH, Source: https://www.daily-bangladesh.com/
