A3 2 Mr Blue Sky

Abstract

This paper outlines what makes the sky appear blue and what changes would need to be made to the Sun in order to create a vastly different coloured sky. We found that a solar system similar to ours could have a sky dominated by any given colour in the visible spectrum. Assuming the size of the star was comparable to our Sun, a surface temperature between 4,458 K and 7,245 K would cover the entire visible electromagnetic spectrum from Red to Violet.
