Manastash Ridge Observatory
Discussion Reviews Photo
3.8k Popularity

Manastash Ridge Observatory, Astronomical observatory near Ellensburg, United States.

Manastash Ridge Observatory is an astronomical observatory located on a ridge near Ellensburg in central Washington state. The facility houses telescopes and other instruments used for night sky observations and atmospheric research.

The University of Washington established this observatory in 1972 with support from the National Science Foundation and the state of Washington. It began operations as a center for both research and teaching in astronomy.

The facility serves as an educational center where undergraduate students gain direct experience with astronomical observations and equipment maintenance through hands-on training programs.

The elevated location provides good conditions for astronomical observations with minimal light pollution. Visitors should prepare for the higher altitude and variable weather conditions typical of the ridge location.

The observatory uses a specialized radar system that receives commercial radio broadcasts from Seattle to detect atmospheric phenomena like meteors and aircraft. This dual-purpose approach makes it an unusual research facility.
