and the related question is why is the sky blue during the day?
The answer is Rayleigh Scattering. http://en.wikipedia.org/wiki/Rayleigh_scattering

Red and orange light is scattered less than other colors by air (and all gases). This is becasue of a phenomenon called Rayleigh scattering.
The light that reaches your eye from the sun at sunrise and sunset has to pass through a much longer layer of atmosphere, since it passes through obliquely rather than straight down from above. This results in so much scattering of the other shorter-wavelngth colors that only red and orange light remain from the direction of the sun. The rest of the light is scattered away to the give blue sky its color.
