Prof. Turner's Work on the North Star Garners International Press

A new distance to the North Star (Polaris) by Saint Mary's Professor David Turner implies that the famed star is 30% nearer than inferred from existing satellite-based measurements. The new distance established for Polaris by Turner and collaborators relies on a high-resolution spectral analysis. “Polaris presents certain anomalies that have so far defied a straightforward interpretation,” noted Dr. Turner. He went on to add that “Our high-resolution spectroscopic observations of Polaris may signal the beginning of a new era in understanding the star.” The research has garnered international press, and has been featured on
