Have you ever driven through a big city at night and marveled at the lighting? Or enjoyed the glimmer of a metropolitan airport when traveling by jet in the dark? Many who appreciate the beauty of a city’s evening illumination might be surprised to discover there can be negative effects from these lights. Perhaps you have pondered the need for all those brilliant orbs which brighten our backyards, parking lots and roadways. That is the topic addressed in Our Vanishing Sky, on view at the Center for History September 3 - November 13. The exhibition explains how outdoor lighting can adversely affect people, animals, and even backyard stargazers. Presenting solutions to myriad problems that occur through the improper use of outdoor lighting, Our Vanishing Sky features hands-on components which provide opportunities to experiment with outdoor lighting concepts. Ways to save energy, increase security, and preserve views of the starry night sky are examined. Visitors can step into a telephone booth-sized area to see a simulated view of the stars, first from a brightly-lit city, then from a rural location. The exhibition explores how light disrupts the internal clocks that make our body cycles work, how the aging eye becomes particularly sensitive to glare and reduction of contrast, and how lights can negatively impact wildlife and their habitats. Our Vanishing Sky was developed by the Evansville Museum of Arts, History and Science with support from the Vectren Corporation.
