How much of the night sky are you able to see from your backyard? Unless you live in a relatively isolated place, odds are you can only pick out a few stars in the darkness.

Since its inception in 2001, the International Dark Sky Association has certified over 130 Dark Sky Reserves, Parks and Communities around the globe. Through these designations, the association has committed to reducing light pollution and preserving the night sky — an element that’s become increasingly difficult to appreciate due to perpetually-expanding cities.
