The sun is truly white, not yellow, as former NASA astronaut Scott Kelly verified on Twitter after a space fact saying the same was shared by the "Latest in Space” account.
The earth’s atmosphere causes the dwarf star, which is truly white, to seem yellow. As a result, the sun looks white once a person has passed through our planet’s atmosphere.
NASA claims that blue light is better attenuated by Earth’s atmosphere than red light.
"The human eye interprets the colour of the Sun as yellow because of the minor blue light shortfall.”
All x-ray and gamma radiation is filtered away before it reaches humans on the ground, according to NASA.
Numerous comments were made underneath the astronaut’s tweet by online users. While some people agreed, others remained doubtful, and other people answered in jest.
