When satellites take pictures of Earth at night, how much of the light that they see comes from streetlights? A team of scientists from Germany, the U.S., and Ireland have answered this question for the first time, thanks to “smart city” lighting technology that allows cities to dim their lights. The results were published today in the journal Lighting Research & Technology.
