Description: Sixty years ago Frank Drake wrote down an equation that has become one of the most famous in astronomy - the Drake Equation. This formula, aiming to estimate the number of alien civilizations communicating within the galaxy, has been celebrated, abused and criticized. Today, we are taking a deep dive into this special equation in a two part special. Written and presented by Prof David Kipping. Thanks to Jason Wright and Nadia Drake for help with this video.
