On November 16, 1974, the first message meant for the stars was broadcast into space, using a series of zeros and ones to encode an image. This image was designed by Frank Drake, an astronomer who helped develop the modern field of SETI as well as the Drake Equation, a formula which helps scientists think about the likelihood of intelligent life in our galaxy.
Fifty years later, the science journalist Nadia Drake, who is also the daughter of Frank Drake, wrote an essay for Scientific American about this message.
In this episode Samuel Arbesman had the pleasure to speak with Nadia about this Arecibo Message. Nadia is a freelance science journalist and former contributing writer at National Geographic.
Nadia and Samuel had a chance to discuss the nature of the Arecibo message and how this "selfie for humanity" was designed by her dad. They talked about SETI more broadly, as well as the wisdom of sending messages into outer space. They talked about other messages sent on behalf of humanity, as well as the nature of technosignatures more generally. They even discussed how the detection of extraterrestrial intelligence might change our lives, or not, and how we think about the world.
