The pics were taken by NASA astronauts from the International Space Station. At first, the pics were not interesting because all of them were blurred, but techniques and devices evolved over the years and now, you can have beautiful clear photos. One interesting thing is that Tokyo seen by night is rather green while other cities are more orange/yellow. In fact, the majority of the urban area in Tokyo has light green mercury vapour lamps instead of orange sodium vapour lamps.
And another thing you can see on these pics is that american cities are neatly squared but the european cities are showing some kind of growth from the center. Its very interesting to see
