It just gradually gets darker as you go higher. For that matter, the atmosphere itself doesn't have a well-defined boundary, it just keeps getting thinner until all you have is an occasional molecule of gas.

it depends what side the sun is on.if it was say 12 noon and you are looking straight up at the sun which is 93,million miles from us.their is nothing but pure light between it and us.their is no dark as such.you would have to travel to another solar system with no suns to have dark.you only see the moon at night because of the reflected light from the sun on it.the stars are a different matter.they are self illuminating suns like our own.its too great a subject to explain properly.
