Earth lit by electric lights!!

The picture above is courtesy of NASA. It depicts earth being lit by electric lights at night time. I was very excited to find this picture and will do everytime I look at it. How about you? Wondering how the whole world can be dark at once? No, this is not a straight photograph, but this is a composition of data taken from various sources.
