Understanding the Color of the Sun

The video explores the true color of the Sun, debunking the common belief that it is yellow. It explains that the Sun appears white when viewed from space, and its perceived color changes due to atmospheric scattering. The video also discusses how the Sun's color is crucial for astronomers, who use spectroscopy to analyze the composition and temperature of stars. The Sun's color is affected by its position in the sky and atmospheric conditions like pollution.
