27 (D-104) Flagstaff by night

27 (D-104) Flagstaff is a special place at night. Why? The city works to preserve its dark skies by keeping light pollution to a minimum. Their objective is “to preserve and protect the nighttime environment and our heritage of dark skies through quality outdoor lighting.” On October 24, 2001, Flagstaff was recognized by the International Dark-Sky Association as the world's first "International Dark-Sky City." Flagstaff has two major astronomical observatories (Lowell Observatory and the United States Naval Observatory Flagstaff Station). Astronomers discovered the planet Pluto at Lowell Observatory in 1930.
