That's what this book is about: other worlds, what awaits us on them, what they tell us about ourselves, and - given the urgent problems our species now faces - whether it makes sense to go.

Should we solve those problems first?

Or are they a reason to go?

About Carl Sagan

Carl Edward Sagan (9 November 1934 – 20 December 1996) was an American astronomer, planetary scientist, cosmologist, astrophysicist, astrobiologist, author, and science communicator. His best known scientific contribution is research on extraterrestrial life, including experimental demonstration of the production of amino acids from basic chemicals by radiation. Sagan assembled the first physical messages sent into space, the Pioneer plaque and the Voyager Golden Record, universal messages that could potentially be understood by any extraterrestrial intelligence that might find them. Sagan argued the hypothesis, accepted since, that the high surface temperatures of Venus can be attributed to, and calculated using, the greenhouse effect. He testified to the US Congress in 1985 that the greenhouse effect will change the earth's climate system.

Additional quotes by Carl Sagan

The book was better than the movie. For one thing, there was a lot more in it. And some of the pictures were awfully different from the movie.

In addition, human beings have, in the most recent few tenths of a percent of our existence, invented not only extra-genetic but also extrasomatic knowledge: information stored outside our bodies, of which writing is the most notable example.

En lugar de juzgar a la gente por sus méritos y defectos individuales, nos concentramos en un par de detalles de información sobre ellos y a continuación los colocamos en una serie de casillas previamente establecidas.
Con eso nos ahorramos el esfuerzo de pensar, al precio en muchos casos de cometer una profunda injusticia.
