Dr. John C. Barentine is an astronomer, historian, author and science communicator. He is currently the Director of Conservation for the International Dark-Sky Association (IDA) in Tucson, Arizona. He earned his master’s degree in physics at Colorado State University and his Ph.D. in astronomy at the University of Texas at Austin. Throughout his career, he’s been involved in education efforts to help increase the public understanding of science. We started with a brief segment on his early career as a observing specialist at Apache Point Observatory in New Mexico. In the second segment, we chatted about his work at the IDA in Tucson, the organization, its goals, and why it’s so important for all of us who live on planet Earth to be able to look up on a clear night and see stars.
