Chris Luginbuhl

Christian Luginbuhl is an astronomer at the United States Naval Observatory, Flagstaff Station, where he has worked on a variety of photometric and astrometric projects since beginning work there as a summer student in 1981. His research has involved star-forming regions, young stars and transient phenomena such as gamma-ray bursters and optical transients. He is also a lover of the natural night. For over 25 years he has been actively involved in light-pollution issues, seeking to preserve the highest quality dark skies through education and research. His efforts focus not only on research to improve our understanding of how light pollution is produced and how it may be limited, but also education to raise awareness of our light-obsessed and environmentally isolated culture of the cultural, scientific and human value of the natural night. And not just for astronomers. He is a founding member of the Flagstaff Dark Skies Coalition (, a nonprofit organization that coordinates and enhances the world-leading sky protection efforts of Flagstaff, Arizona, the World's First International Dark-Sky City. Every two years the Coalition and Chris coordinate the production of "NightVisions," an international fine art exhibit that celebrates the beauty and wonder of a dark, star filled night, and the inestimable value it brings to human life and culture.

Chris Luginbuhl, an astronomer with the U.S. Naval Observatory in Flagstaff, Arizona and expert on Dark Skies, was the guest for this Space Show program. Dark Skies or the use of star friendly lighting was the main theme and discussion subject for this program. We discussed the need for star friendly lighting, why people other than astronomers should care about it, and how to go about working for Dark Sky policies in city building codes. Mr.
