Is the Sun White in NASA?
The Sun is actually white. This is confirmed by NASA and various sources. While it appears yellow or even orange from Earth due to atmospheric scattering, in space, the Sun's true color is revealed.
-
Earth's Atmosphere: The Earth's atmosphere scatters shorter wavelengths of light (blue and violet) more effectively than longer wavelengths (red and yellow). This scattering causes the Sun to appear yellowish or reddish during sunrise and sunset, and generally less white during the day.
-
Spectral Emission: The Sun emits light across the entire visible spectrum. When all these colors combine, they create white light. As noted by NASA, the Sun emits most of its energy around 500 nm, which is close to blue-green light, however, the combination of all wavelengths results in white light. https://eclipse2017.nasa.gov/what-color-sun

Space Observations: Images and observations from space clearly show the Sun's white appearance, free from the distorting effects of the Earth's atmosphere. https://www.ndtv.com/world-news/the-sun-is-actually-white-ex-nasa-astronaut-confirms-space-fact-3340514

NASA's Perspective: While NASA uses various color filters and imaging techniques to study different aspects of the Sun (like temperature and regions), their findings consistently support the Sun's true color being white. https://svs.gsfc.nasa.gov/vis/a010000/a013800/a013859/script_31299_00.html
