    on earth we see the sky through a lot of AIR

    and that acts as a filter to give the blue tint

    but notice at other times there may be any other colors present

    its just a matter of the angle of the light passing through &

    the water vapor present ( etc...)

    in space, there isn't any air to filter the light so its either light

    where there is a light source ( like the sun ) or its dark because

    there isn't any air.

    The sky appears blue to us on a clear day, because the atoms of nitrogen and oxygen in the atmosphere separate the suns white light into its many colors, and scatter them throughout the atmosphere. The wavelength of the blue light scatters better than the rest, predominates over the other colors in the light spectrum, and makes the sky appear blue to us. The scientific name for this phenomenon is the Tyndall effect, more commonly known as Rayleigh scattering.

    the solar interacting with the Earth's ecosystem makes the sky blue. In outer area the astronauts see blackness with the aid of fact outer area has no ecosystem. solar contains sunshine waves of various wavelengths, each of it is considered as a diverse shade. The minute debris of count number and molecules of air interior the ambience intercept and scatter the white gentle of the solar. a greater element of the blue shade in white gentle is scattered, greater so than the different shade with the aid of fact the blue wavelengths are the shortest. while the size of atmospheric debris are smaller than the wavelengths of the colors, selective scattering happens-the debris in straight forward terms scatter one shade and the ambience will seem to be that shade. Blue wavelengths distinctly are affected, bouncing off the air debris to come lower back into sight. it particularly is the reason the solar seems yellow (yellow equals white minus blue). At sundown, the sky modifications shade with the aid of fact with the aid of fact the solar drops to the horizon, solar has greater ecosystem to bypass with the aid of and loses greater of its blue wavelengths. The orange and crimson, having the longer wavelengths and making up greater of solar at this distance, are maximum in all probability to be scattered with the aid of the air debris.

    The colour of space is actually Beige - http://www.dailyrecord.co.uk/news/weird-news/2009/...

    The sun rays shines into our atmosphere the blue particles in the spectrum get trapped into our atmosphere thus giving the sky a blueish look, this is also why water is bluish too :D

    Long story short: Blue light is easily seen in our atmosphere and once you're out of our atmosphere, the sun's visible light spectrum is faltered.

    The earth's atmosphere reflects the blue color from our beautiful oceans.

    because of the way light scatters in the atmosphere
