Why are green stars not commonly observed in the night sky?
Answer
Light from stars is spread across a broad spectrum
Stellar physics dictates that while a star might have a peak emission in the green part of the spectrum, it does not produce a pure green light. Instead, the light is spread across a broad range of wavelengths. The human eye interprets the combination of these various wavelengths as white, meaning green stars do not appear as distinct, pure colors.
