During a total solar eclipse, the sun can sometimes appear to take on a greenish hue. This unusual phenomenon is primarily due to Rayleigh scattering, which is the same effect that makes the sky blue and sunsets red. When the moon completely covers the sun, the atmosphere scatters sunlight in such a way that shorter wavelengths, particularly blue and green light, are more prominently visible. This can create a striking contrast against the darkened sky, leading to a brief moment where observers may see a green sun. While this color is not commonly reported, it highlights the intricate interplay between light and atmospheric conditions, reminding us of the wonders of our natural world and the scientific principles at work during such celestial events.
