Cosmos by Carl Sagan was first published in 1980 as the companion to his PBS series Cosmos: A Personal Voyage, and it became one of the best-selling science books ever written. This is the Ballantine paperback edition, with a foreword by Neil deGrasse Tyson and an introduction by Ann Druyan.
It covers the history of science, the evolution of stars and life, and humanity's place in the universe, told with a sense of wonder that still inspires scientists decades later. For anyone who loves science - or should - it is the gift book that never goes out of date in spirit.
It was written in 1980, so some of the science has moved on - it is a classic for its outlook and storytelling rather than a current reference.
Skip for someone who has already read it, or wants the latest research.
