Experience an unscripted conversation between two icons who have indelibly shaped our culture’s view of space.

Where do you go to let your curiosity fly? The backyard, of course. The setting for this audio original program is the backyard of William Shatner’s Los Angeles home, where he and Neil deGrasse Tyson enjoy a powerful, open-hearted conversation steeped in wonder. Having become fast friends and verbal sparring partners, the two men discuss the quest for knowledge that has driven human exploration and discovery over centuries, drawing from historical and contemporary examples. They discuss their efforts to overcome societal biases, Shatner’s as a Jewish kid growing up in Montreal, Canada and Tyson’s as a Black kid from the Bronx. They also share stories of how and when their individual futures took flight: Shatner’s path leading to Star Trek and a long career in film and television, and Tyson’s path to becoming a globally recognized astrophysicist, author, and science communicator. Of course, they also go deep on topics of great interest to them both, including black holes, the behavior of light, quantum physics, the beauty and complexity of the universe, and even spirituality.
