In October 2020, Faena Rose hosted a conversation with Avi Loeb, Harvard’s Astronomy Department’s longest serving Chair, who argued that our solar system has likely been visited by advanced alien technology. Dr. Loeb is back to share ideas from his new book, Interstellar. This work reimagines the idea of contact with extraterrestrials and explains why humans must seek out other life forms and “choose who and what we are within the universe.”
