From ABC: Darkened Cities: The Night Sky You Don’t See

For city-dwellers, the night sky can be unimpressive because of light pollution. Cities are often awash in light, masking out all but the brightest of stars and planets. Step outside a major metropolis, though, and the heavens become a sea of stars.

French photographer Thierry Cohen has found a way to combine city and country views to show what urbanites have been missing. He photographs major cities, noting the precise time, angle, and latitude and longitude of his exposures. He then shoots the sky at the same angles from remote places at the same latitude, and digitally combines the images to show what the night sky would look like if we could turn out the lights.
