Not only is the picture slightly sci-fi and weird, it's also wrong. I mean, my thought processes on seeing it went something like this: "Oh, hey, it's a ringworld. Presumably this is meant to hint at the glorious future that might be ahead of us if we don't get wiped out, and therefore the importance of not getting wiped ou ... no, wait a moment, it's kinda like a ringworld but it's really really really small. Much smaller than the earth. What the hell's the point of that?"

Yes. The part that looks like a sky in the picture is some transparent material that holds the atmosphere in.
