A Technological Civilization by Night

Of course, what gets my attention is that this is what a technological civilization -- the only one we know exists -- looks like by night to an approaching spacecraft. Will we one day have interstellar probes that can make a Rosetta-style pass around a world like this in another solar system? For that matter, will we ever have the kind of spectacular close-up images that could result from advanced sunshade concepts like New Worlds, showing us the lights of alien cities?
