FILE - In this Aug. 1996 file photo, astronomer Carl Sagan speaks in Washington. The Library of Congress has acquired the personal papers of the late scientist and astronomer Carl Sagan, thanks to the generosity of a well-heeled admirer: “Family Guy” creator Seth MacFarlane. The writer, director and actor is working on a follow-up to Sagan’s acclaimed “Cosmos” miniseries, which introduced a mass audience to the mysteries of the universe and the origins of life. MacFarlane says he was profoundly influenced by “Cosmos” and wants to draw attention to the need for continued exploration of space and study of astronomy. (AP Photo/John Duricka, File)
