Harvard professor Avi Loeb explores his theory in a new book and in a fascinating conversation with Mat Kaplan.Could the first object shown to have originated outside our solar system be a light sail built by an alien civilization?

Bill Nye pays tribute to a fallen member of The Planetary Society’s space family, and the biggest coincidence in the history of Planetary Radio surfaces during What’s Up.There’s more to discover, including a link to Planetfest ’21, at https://www.planetary.org/planetary-radio/0127-2021-avi-loeb-extraterrestrial
