ONLINE – General Meeting – January 2022

6:30 pm – Main Presentation

Title:  Dark Skies in Southern Arizona: Past, Present and Future

Presentation:  John Barentine, astronomer, historian, and policy-maker will present on the global dark-skies movement. That the movement effectively began in the Tucson area, is no surprise given its long astronomical history. In his presentation, John will review regional achievements to date and the challenges we face in the coming decade that involve the balance of managing growth and sustaining astronomy’s contribution to the local economy. Lastly, he will touch on satellite ‘megaconstellations’, an issue not limited to our region, but of increasing concern to professional and amateur astronomers alike.

Presenter:  John Barentine is the Principal Consultant at Dark Sky Consulting, LLC, and was formerly the Director of Public Policy for the International Dark-Sky Association. He earned a Ph.D. in astronomy from the University of Texas at Austin, and previously held staff positions at the National Solar Observatory, Apache Point Observatory, and the Sloan Digital Sky Survey. Throughout his career, he has been involved in educating the public about science. He is a member of the American Astronomical Society and the International Astronomical Union, and is a Fellow of the Royal Astronomical Society. The asteroid (14505) Barentine is named in his honor. His interests outside of astronomy and light pollution research include history, art and architecture, politics, law and current events.
