One remarkable thing about this image is that not only did all the idividual photos that make it up have to be selected from night photos, but they had to further discriminate by eliminating all photos with clouds.
The most amazing thing about that picture is the very distinct line that is visible on the Korean peninsula. South Korea is very bright and North Korea is very dark.
I'd hope they had a few lights and development "The population of India as at 0:00 hours on 1st March 2001 stood at 1,027,015,247 persons. With this, India became only the second country in the world after China to cross the one billion mark. India's population rose by 21.34 % between 1991 - 2001."
