If I was able to colonize a portion of space with oxygen, would the sky still be black when sunlight passes?

Question

I do not intend to suggest filling the entire vacuum of outer space. I am just asking if I was somehow able to “colonize” a tiny portion of outer space with oxygen, would the “sky” still be black or would it be blue like it is here on Earth?

Answer 1

If you were able to create an Earth-like atmosphere on a planet, then it would scatter sunlight just as Earth's does and the sky would be blue and bright when the sun was on it. If you just have a pressurized dome (a more technologically feasible situation), there wouldn't be enough air to significantly scatter light and you could look out of the dome and see black sky.

Answer 2

I think that it would be black instead of blue. I think that the sky of the portion of space would be pitch black because the sky would be dependent on which planet you are on. If you look down on the planet earth from a satellite you would see blue because of the background color of earth. It is blue because the ocean is blue hence the background of earth is blue. However if you go to another planet like Mars the background is red because it has different gases on Mars. Therefore the sky on every single planets have different colors due to their background (their surface) and their gases. Pluto, Venus, Mars, Earth's gases are all different. In conclusion I believe that if you were to colonize a portion of space and sunlight passes throught it, it would be black because the Sun's arrays would reflect light to 'empty space' and hence no object to bounce the light back to give that particular color like blue on Earth or red on Mars. 'For example if you see a satellite picture of Northern Africa it is mild red because that area is covered with desert.'

Answer 3

A lot of oxygen or air would be required in order to scatter light effectively so that the sky looks blue.

Answer 4

sky is clear. during ozone layer don't let sun go thru all th way that's y it's blu, and night u see emptyness of the universe. and it would be same thing as if u could colonize prt of universe with oxygen. it just makes a planet bigger i think.
