Description

Frank Drake, a prominent radio astronomer and SETI (Search for Extraterrestrial Intelligence) pioneer, passed away in 2022. He developed a way to estimate the number of civilizations in our galaxy. He conducted the first modern SETI search using a radio telescope, composed a message sent from Arecibo into the void, and even contemplated life on the surface of a neutron star. How do we even begin to estimate the number of ET civilizations? How has SETI progressed since Drake’s time? What does the discovery of thousands of exoplanets tell us? Could life take the form of city-sized atmospheric jellyfish, clouds of ionized gas or even be powered by nuclear reactions? Explore these and other fascinating topics in a mind-bending tour of the contributions of Frank Drake and their aftermath.
