Since Percival Lowell established his observatory here in 1894, Flagstaff has worked to keep its night skies dark. So it probably shouldn’t come as a surprise that it became the world’s first International Dark Sky City in October 2001. During the day, you can see where Pluto was discovered at Lowell Observatory or view the sun through Lowell’s specially equipped solar telescope. At night, look through telescopes at the moon, planets, and star clusters.
