Night Sky and Night Vistas
Henry Heatwole (NPS Photo)
The human connection with night skies has had a long history. The stars and planets have had centuries of religious and cultural affiliation. They have been used in a utilitarian mode by those that depended upon them for navigation. Stellar and planetary positions and movements have influenced planting and harvesting of crops. Many species of wildlife are influenced in their activities by star and moon light.
It is anticipated that night sky viewing within the Shenandoah will become increasingly more important as visitors seek out locations where better views of the sky are available away from their urban and suburban living circumstances. Finding and observing constellations, phases of the moon, meteor showers, and eclipses provide opportunities for perspective regarding the environment in which we live and open doors to intriguing aspects of science education. There are about 2500 stars visible to the unaided eye from earth’s surface on a dark, moonless, and cloudless night. As the awareness of visitors and policymakers grows, the night sky is now being acknowledged as an important park resource.
Little about the night sky at Shenandoah has been formally documented. Public interest, while known to exist, has not been tracked or recorded. The variability in night sky viewing caused by location and proximity to sources of light pollution as well as different atmospheric conditions, which may include air pollution levels, has also not been documented. Intuitively it is known that better viewing occurs further away from ground-level lights and when it is cool or cold when humidity is lower. No quantification of relative viewing conditions has occurred.
Interestingly, here at Shenandoah, an additional twist associated with the night sky must be recognized. In most cases, improving night sky viewing opportunities involves reduction in light pollution so that people can see stars and planets above. But here at Shenandoah, some of what would otherwise be regarded as light pollution is actually visually attractive to some. Many park visitors stand at overlooks along
