Kat, the shots that show night views in this series is a combination of technical data from USAF satellites that were designed for detection of missle launches and other nefarious activities and computer generated maps of the globe. They are NOT photographs. (You may note that there are no clouds anywhere on the planet.)
In the real world you would not be able to view the sunlit and nighttime areas at the same time...too much difference in brightness for even the wonderous human eye to record in the same instant.
Also, the night images are amplified compared to what you would see with unaided eyes. That's not to say that you could not see lights of cities, towns and villages. Just not this bright.
On the other hand, isn't it a lovely planet?
