What it's about

Written alongside his landmark TV series, Carl Sagan's tour of the universe covers fifteen billion years of cosmic history: how stars are born and die, how life might have begun, what we've learned from planets and comets, and the long human story of how science pieced it all together, from ancient Greek astronomers to the Voyager spacecraft. Throughout, Sagan asks what our place is in a universe so vast.

Why it's worth reading

Sagan makes science feel like wonder, and his prose can make you see the night sky differently for the rest of your life. Some details have dated since 1980, but its spirit hasn't.

Good to know

Some science is out of date (it predates exoplanets and dark energy), which most readers find part of its charm. No math is needed.

Critics and Bestseller are two ways to earn a place: a book's stronger one counts more. Buzz rewards recent bestseller weeks and prizes, so older books start at zero.

National Book Award (Nonfiction) finalist (1981). One of the best-selling books ever (about 40 million copies). 4.40★ from 165K Goodreads ratings.
