United States Naval Observatory Flagstaff Station, Astronomical observatory in Flagstaff, United States
The United States Naval Observatory Flagstaff Station is an astronomical facility located in Arizona's mountains in a region with very dark skies. The site has several telescopes used to measure star positions and monitor binary star systems.
The observatory was established in 1955 to conduct astronomy far from urban light pollution. Its work later led to significant discoveries, including the observation of a moon orbiting a distant planet.
The facility contributes to understanding the night sky by regularly collecting data on stars and their movements. These measurements help navigators and scientists worldwide stay oriented.
The location sits at high elevation with favorable conditions for sky observations and features specialized equipment for precise measurements. Visitors should be aware that the facility is primarily a research operation and access may be limited.
The facility plays a dual role by conducting scientific research while also providing data for military and civilian navigation systems. This combination makes it a place where space exploration and practical applications meet.
