      Great question. The Sun is a black body (near enough) meaning it emits radiation for the full spectrum of Electromagnetic radiation. When the light hits our atmosphere, it is travelling through a different medium and is scattered. Blue is shorter than the other colours of the visual part of the spectrum and therefore scattered more than the others, which is why we see a blue sky most of the time.
