Pale Blue Dot is a book by Carl Sagan. First published by Random House in 1994, it is the sequel to the book Cosmos.


Inspired by the famous 1990 Pale Blue Dot photograph, Sagan mixes philosophy about the human place in the universe with a description of the current knowledge about the Solar System.
