Description
"Fascinating . . . memorable . . . revealing . . . perhaps the best of Carl Sagan's books."--The Washington Post Book World (front page review) In Cosmos, the late astronomer Carl Sagan cast his gaze over the magnificent mystery of the Universe and made it accessible to millions of people around the world. Now in this stunning sequel, Carl Sagan completes his revolutionary journey through space and time. Future generations will look back on our epoch as the time when the human race finally broke into a radically new frontier--space. In Pale Blue Dot, Sagan traces the spellbinding history of our launch into the cosmos and assesses the future that looms before us as we move out into our own solar system and on to distant galaxies beyond. The exploration and eventual settlement of other worlds is neither a fantasy nor luxury, insists Sagan, but rather a necessary condition for the survival of the human race. "Takes readers far beyond Cosmos . . . Sagan sees humanity's future in the stars."--Chicago Tribune… (more)

It lets you in a state of expectation and optimism for the things we can achieve in future generations, this sensation can be best summarized
"Sailors on a becalmed sea, we sense the stirring of a breeze."
That said, this book is outstanding if one considers the date it was published. Young
The big take away for me was that we 'humans', are not the center of anything but our own imaginations. Our place in the cosmos is so insignificant, that it's not even worth mentioning. And to think we are so smart, is laughable.
Thank you Dr. Sagan, and rest well.

When
The fascinating parts of the book start after that. They are about the worlds in our solar system, how planets and moons form, and the vision for human Space exploration. Fantastic. If it was science fiction it would be great science fiction (just add characters), but it is science which just makes it even greater.
The book is of course 20 years old, and a lot has been discovered since it was written, but mostly not described as eloquently as Sagan can do it. My husband and I read the book together second time (I read it up for him as goodnight story), and have used Wikipedia on my tablet to update ourselves about the later discoveries after each chapter, so when we finish reading about a planet or moon we go to Wikipedia to get the latest space exploration updates about it before moving on. I can recommend that reading strategy.
Future generations will look back on
A full chapter details the conflicts between science and religion in the early Catholic church and argues that the human race gained a measure of humility after reluctantly accepting the fact that we are not at the center of the universe. As he did often in Cosmos, Sagan delves into the history of astronomical advancements including early discoveries of the larger moons around Jupiter, Saturn, and Uranus by Galileo, Huygens, Cassini, Kuiper, and Lassell as well as the naming (and renaming) of the first seven planets by the ancients—Earth, Moon, Mercury, Venus, Mars, Jupiter, Saturn—and how this inspired the development of the seven-day calendar week.
Readers are also treated to rich scientific detail about the planets and 60 plus natural satellites in our solar system based on data from the Viking, Galileo, Cassini-Huygens, Pioneers 10 and 11, and Voyager 1 and 2 probes. Further chapters delve into the atmospheric and surface compositions of the worlds, asteroids, and moons before Sagan goes on to expound three major threats to Earth’s environment—ozone depletion, global warming, and nuclear winter.
Sagan’s hopes and visions for the future of manned space exploration through international cooperation are inspiring for all their possibilities, but he is also pragmatic and laments the financial erosion and bureaucratic ossification of the space program over the past three decades and an unfortunate public shift in focus away from planetary exploration. However, in 1994, when Pale Blue Dot was published, it’s difficult to say whether Sagan predicted the dawn of private space agencies—such as SpaceX, Virgin Galactic, Blue Origin, and others—that would fill the void left by the government.
As always, Carl Sagan makes it clear that by exploring other worlds, we open our minds to possibilities far beyond the scope of our limited knowledge and experience bound up on this insignificant pale blue dot situated on the outer edge of a spiral arm lost among billions of stars and planets in the Milky Way.
“We’re made of star stuff. We are a way for the cosmos to know itself.” – Carl Sagan, Cosmos.
And that is what this book does to a greater degree. It’s a sobering reminder of what we are, where we are, and when we are. It’s also a glimpse into our future of reaching into space, conquering the final frontier and ushering in an era of peace and progress. While the last bit seemed far fetched in the 80s and 90s - and even more so now - the message is clear: we need to forget our differences - be they political, religious, or economical - and forge our future together.
Sagan uses the book to argue space travel in the 90s. Yes, we have come a long way since then, and some of the information is extremely outdated in 2015, but the warrant remains the same. His thesis is clear and the writing is sharp, which results in a highly persuasive read that will convert even the most hardcore anti-spacers out there.
I believe I’ve said more than enough about the book. Stop reading and go grab the book right now and immerse yourself in Sagan’s beautiful prose. You’ll lose yourself among the vastness of space, yet you won’t be alone.
Xenophanes understood the arrogance of this perspective:
The Ethiopians make their gods
After showing how arrogant and stupid humanity has been Sagan still makes the plea that we somehow save ourselves, by going out into space. That way our entire species future isn't tied to a fragile planet that we ourselves might destroy through our misuse of technology or through war.
I think we are closer now to the destruction that Sagan feared even more so then in 1994, I'm afraid we don't have enough time left to colonize the planets, asteroids, and comets like he proposed. Steven Hawking repeated the plea in 2008. Personally I think, our efforts should be two fold, first try to get some human presence off of earth as quickly as possible, secondly try to develop as sophisticated an AI as possible, and send that off planet, as a hedge that even if humanity is completely destroyed we would have left something behind.
Pale Blue Dot had some fabulous insight into the difficulties behind space exploration, particularly on the political and bureaucratic end. However, it frequently goes off topic, where
A bit jumbled, and takes on too much, but a fascinating read nonetheless.
