Nighttime satellite images of North Korea suggest that the country's economic conditions have slightly improved since a famous satellite photo that shows the country in pitch darkness next to the brightly sparkling South.
Kim Kyu-chul of the Korea Development Institute analyzed nighttime luminosity in North Korea based on satellite images from 1992 to 2013. "The North has brightened since 2000", Kim said in a report published Monday.
