The sky is blue due to the refraction of light (much like when passed
through a prism) through the slowly depleating ozone layer, which is
supposed to filter out the ultraviolet light.

>  - and the second is "is the sky blue" and the answer is YES !

Yes, except when the sun is down, then its a black or very dark gray,
depending on your eyesight :)

Preferably not :)
