SUMMARY

Stars emit light across a broad spectrum of wavelengths, which is why green stars do not exist. Our eyes perceive colors based on specific narrow wavelength bands, and the light emitted by stars does not fall within the precise range required for green perception. This phenomenon is rooted in the physics of light and human vision, explaining the absence of green stars in the universe.

PREREQUISITES
  • Understanding of electromagnetic spectrum
  • Basic knowledge of human vision and color perception
  • Familiarity with stellar classification
  • Concept of light emission in astrophysics
NEXT STEPS
  • Research the electromagnetic spectrum and its implications in astronomy
  • Study the physics of light and color perception in humans
  • Explore stellar classification and the characteristics of different star types
  • Investigate the properties of light emission in various celestial bodies
USEFUL FOR

Astronomy enthusiasts, astrophysicists, educators in physics, and anyone interested in the science of light and color in the universe.

Stars seem to occur in almost every color, from red to near violet, but not green. Why are there no green stars?
 
Astronomy news on Phys.org
Because our eyes perceive things as green only if the light emitted is in a very narrow wavelength band. Stars emit light in broad bands.
