Where should you travel if you want killer views of the stars unblemished by artificial light?

Certainly not the U.S. or Europe, where nearly 100 percent of the population endures some form of light pollution. And maybe skip South America, Asia, and Australia, too, as their citizens are among the 80 percent globally that live under human-lit skies. Best head to Chad, Madagascar, or the Central African Republic; more than three-quarters of locals there enjoy views of a coal-black abyss stippled with glimmering, gaseous diamonds.
