For those who have never heard of the Dark Sky' movement, this is an initiative aimed at reducing light pollution. Among the many benefits are an increase in the number of stars visible at night, energy savings and a better quality of life for people and wildlife. Arizona has more "Dark Sky" certified locations than anywhere else in the world and many communities in this western U.S. state have been certified by the International Dark Sky Association (Big Park, Camp Verde, Flagstaff...). Without forgetting the nine parks also certified among which the Grand Canyon National Park and the Petrified Forest National Park. Proof that it is indeed in Arizona that you should go when you appreciate the vast starry skies that give nature such a mysterious and grandiose aspect. Arizona is also home to several observatories and planetariums, and in 2021, the International Dark Sky Discovery Center is scheduled to open in Fountain Hills, with four distinct and educational attractions: planetarium, observatory, theater and an immersive zone offering interactive exhibits and an experience recreating a Dark Sky.
