To help meet the demand for night sky interpretive programs, the National Park Service Night Sky Program last year recruited 19 volunteer astronomers from around the country who were then placed in national parks, started a loaner telescope collection, produced audio podcasts and brochures, and supported the stellar night sky poster art by Dr. Tyler Nordgren, an astronomer at the University of Redlands, California.Nordgren spent a one-year sabbatical in national parks where he collected his experiences into a book and drafted the series of 14 posters that harken to the Works Progress Administration posters of the 1930's. The full series of night sky posters is available for browsing here.
