In his new book A History of the Universe in 21 Stars: (and 3 imposters) science writer Giles Sparrow guides you through 21 celestial bodies you can see in the night sky and what they can teach us about our universe. From red giants, quasars and supernovae to black holes, join us for a look at how we came to unravel the mysteries of the cosmos in this installment of Leonard Lopate at Large on WBAI.
