Space is dark and yet we see blue Sky's between earth and the moon when visible. Why is that?
- StratmanLv 41 decade agoFavorite Answer
It really has nothing to do with the Moon itself. Sunlight is relected and refracted as it passes through Earth's atmosphere. The portion of the light spectrum you see is usually blue, but at times we see reds, pinks, etc. like at sunset, due to atmospheric conditions. The other colors of the visible spectrum are absorbed, and not reflected to be seen by the naked eye.
Basically, we see blue because we have an atmosphere.
There you have it.

It is visible, but only if you know what you are looking for. The atmosphere is very thin compared to the size of the Earth. Looking down through it the brightness of the the things below is more than enough to show through it clearly. If you look at images of the Earth's limb taken from low Earth orbit you can see the layer of blue atmosphere right at the edge.

Any light source travels in space. but we can the light only if we have a reflecting medium. we see blue sky only in the the atmosphere on the earth. This is possible due the refleection of earth.

Ions in the upper atmosphere absorb UV and blue light then reemit that light scattering the light and giving the atmosphere a blue tint

Because the Sun's rays reflect the oceans blue color and projects it on the atmosphere.
