Recall that red light has a relatively long wavelength, while blue light has a relative short wavelength. It turns out that shorter-wavelength light is more strongly affected by Rayleigh scattering in our atmosphere, causing the bluer shades of sunlight to be scattered far more than the redder shades. This causes the blue light from the sun to appear to come from all over the sky, while the rest of the colors mostly appear to be confined to the sun’s disc. Instead, the blue color of the sky has to do with an effect known as Rayleigh scattering.

So these particles scatter more effectively the light rays of shorter wavelength at the blue end than light of longer wavelengths at the red end. Space is black because there are no substances or objects to reflect back any color . That is also why the astronauts see the earth as we see it in photos, but the space around it is black. Sky from earth appears blue because the sun’s rays get reflected by the water and makes space look blue in colour.
