Dr. John Barentine's talk is titled: Arizona's Night Skies: Past, Present, and Future. Dark night skies loom large in Arizona’s history, and are part of why the Grand Canyon State became known as a global mecca for astronomy and space science. Access to natural nighttime darkness remains an important issue in Arizona’s current politics and plays a role in its future, as light pollution from its cities reaches ever further into the corners of our state. Dr Barentine will review the archaeological and historical evidence for astronomy in Arizona’s past, its development into an astronomy powerhouse in the 20th century, and threats to our night skies posed by population growth and land development in the 21st. Finally, he will offer listeners some practical tips on simple things they can do to help preserve Arizona’s heritage of dark night skies.
Come explore the skies with us!
