Audio is now up for Dave Davies’ interview with Marc Kaufman about astrobiology and the search for life in the universe. Enjoy!
Today’s Fresh Air is about the ongoing search for life in the universe: “There are undoubtedly billions or trillions of planets out there and there are most likely billions in the Milky Way itself — just one of billions of galaxies. There are billions of planets in habitable zones in relation to their stars that would allow for water to be liquid and for other important conditions for life.”
