Online Highways Home > Arizona > Flagstaff City Map with Features Lowell Observatory Built in 1894 by Massachusetts mathematician and amateur astronomer Dr. Percival Lowell in an attempt to better observe the planet Mars, Dr. Lowell hoped to prove the existence of life. For this purpose, Lowell designed the 24-inch Clark refracting telescope; the instrument is now a National Historic Landmark and still in use at Lowell. Other historic instruments at the Mars Hill site include the 16" John Vickers McAllister telescope, now used for public night viewing. The observatory is the site of major modern astronomical discoveries such as the ninth planet, Pluto, and the rings of Uranus. Lowell Observatory continues to play a strategic role in astronomical research, as well as providing public outreach and education programs. Visitors and groups are welcome and special programs and events are scheduled throughout the year. The observatory is open year-round and hours vary seasonally.
