    Brandonord, the sky is blue due to scattering of the light from the sun by dust, particles, and gas molecules in the air. When light hit dust and other particles in the air it get reflected, but that reflected light is still white light. When light hits gas molecules most of the shorter wavelengths of light such as the violet, blue, and green colors are absorbed by the molecules and the blue light is the predominant color emitted or radiated from the molecule. This blue light is scattered in all directions as the white was initially and since our eyes are more sensitivity to blue light we see the sky as blue in color. Once we get beyond the earth's atmosphere space is black because there are not enough particles in space for light to hit, therefore there is nothing to see but black. Keep in mind we only see light if it is visible light emitted from a light source or reflected from an object.

    1. Outer space contains virtually no gas/dust to scatter light.

    Outer space is black.

    2. The sky is blue because that's the colour of air (mostly nitrogen), which is not totally colourless. You can see this effect looking at distant (10 km-plus) mountains. They have a blue tinge (caused by the intervening air between you and the mountains) known as atmospheric perspective.

    3. If the sky's colour was due reflection from the oceans, then it would be white above Antarctica, which is snowy white.

    The sky has a special refraction effect on the sun that blue light is reflected and the other colors are absorbed. Outer Space is black because it has only stars to light it up and since stars produce so much light, outer space remains black. Outer Space actually is bright in its own way.
