Why Stars Shine in Many Colors but Never Green

quick Summary

• Stars exhibit various colors like blue, white, yellow, orange, and red based on their surface temperature.
• the hottest stars are blue with temperatures between 10,000 to 50,000 Kelvin (K). Cooler stars appear yellow or red.
• The Sun is technically white but appears yellow due to the EarthS atmospheric scattering.
• Twinkling of stars is caused by the distortion of their light passing through Earth’s atmosphere.
• Examples of colorful stars include:

– red: Betelgeuse in Orion constellation
– Blue: Rigel in Orion constellation
– Yellow: Capella in Auriga constellation
– Reddish-orange: antares in Scorpio constellation

• Optimal stargazing requires avoiding light pollution and using tools like binoculars or telescopes.
• Green stars do not exist because human eyes interpret mixed wavelengths of green with other colors as white or a different shade. Stars typically emit varied wavelengths that influence perceived color.
