Air pollution stretches from Beijing to Shanghai, as seen from space

NASA’s Terra satellite captured this image of a long belt of smog stretching from Beijing (in the upper third of the image) to Shanghai (in the bottom right corner). That distance is roughly 1,200 km or about the distance from Boston, MA to Raleigh, NC. While smog and air pollution is fairly routine, it is less common to see smog stretch so far south.
