NASA has posted a recent satellite photo of Beijing and Tianjin at night. The photo actually shows a large swathe of the area that Greater Beijing would encompass. NASA’s population number for Beijing is wrong; Beijing already has nearly 20 million residents.
I wonder how many more lights there will be in a similar photo taken in 2020?
UPDATE: NASA has the picture reversed. I flipped it so that Beijing is in the upper left corner of the photo. END UPDATE
