‘Oumuamua: Avi Loeb says it may have been artificial

Could the first object shown to have originated outside our solar system be a light sail built by an alien civilization? That’s the very controversial hypothesis put forward by distinguished Harvard astrophysicist Avi Loeb in his new book Extraterrestrial. The book is about much more than ‘Oumuamua, and so is Avi’s conversation with Mat Kaplan. 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
