A POPULATION GONE VIRAL
November 26, 2013
The photo of earth, a composition of satellite images taken in1985 and originally posted as an APOD photo, later was replaced in the APOD archives with (I think) the 2010 image similarly constructed. Fortunately, I already owned the poster of the original posting and have used it numerous times to show the increase in population from 1985 to 2004. the next image issued as a poster by NASA. The 1985 image is virtually unique in showing the aurora borealis. APOD's treatment of its archive has made me very cynical.
