Pale Blue Dot: A Vision of the Human Future in Space [Hardcover]

Carl Sagan (Author)

Book Description

Publication Date: November 8, 1994

"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

From Publishers Weekly

In a tour of our solar system, galaxy and beyond, Cornell astronomer Sagan meshes a history of astronomical discovery, a cogent brief for space exploration and an overview of life-from its origins in the oceans to humanity's first emergence to a projected future where humans "terraform" and settle other planets and asteroids, Earth having long been swallowed by the sun. Maintaining that such relocation is inevitable, the author further argues that planetary science is of practical utility, fostering an interdisciplinary approach to looming environmental catastrophes such as "nuclear winter" (lethal cooling of Earth after a nuclear war, a widely accepted prediction first calculated by Sagan in 1982). His exploration of our place in the universe is illustrated with photographs, relief maps and paintings, including high-resolution images made by Voyager 1 and 2, as well as photos taken by the Galileo spacecraft, the Hubble Space Telescope and satellites orbiting Earth, which show our planet as a pale blue dot. A worthy sequel to Sagan's Cosmos. Author tour.

From Booklist

Sagan's great appeal as a popular-science writer, beyond his prodigious knowledge, is his optimism and sense of wonder. A visualizer and a visionary, he fires our imagination and turns science into high drama. After writing about our origins in Shadows of Forgotten Ancestors (1992), Sagan turns his attention to outer space and takes up where Cosmos left off 14 years ago. An astonishing amount of information was amassed during that productive era, and Sagan, of course, is up on all of it. A passionate and eloquent advocate of space exploration, he believes that the urge to wander, and the need for a frontier, is intrinsic to our nature, and that this trait is linked to our survival as a species. Throughout this beautifully illustrated, revelatory, and compelling volume, Sagan returns again and again to our need for journeys and quests as well as our unending curiosity about our place in the universe. Such philosophical musings are interwoven with precise and enthusiastic accounts of the triumphs of interplanetary exploration, from the Apollo moon landings to the spectacular findings of robotic missions, especially the Voyager spacecraft. Sagan describes one exciting discovery after another regarding the four giants--Jupiter, Saturn, Uranus, and Neptune--and their many moons, mysterious and exquisite rings, and volatile atmospheres. He argues, convincingly, that planetary exploration is of immense value. It not only teaches us about our celestial neighbors, but helps us understand and protect Earth. Yes, we have seemingly insurmountable problems on this pale blue dot, but we have always reached for the stars, and we mustn't stop now. Donna Seaman

More About the Author

Carl Sagan was Professor of Astronomy and Space Sciences and Director of the Laboratory for Planetary Studies at Cornell University. He played a leading role in the Mariner, Viking, and Voyager spacecraft expeditions to the planets, for which he received the NASA medals for Exceptional Scientific Achievement. Dr. Sagan received the Pulitzer Prize and the highest awards of both the National Academy of Sciences and the National Science Foundation, and many other awards, for his contributions to science, literature, education, and the preservation of the environment. His book Cosmos (accompanying his Emmy- and Peabody Award-winning television series of the same name) was the bestselling science book ever published in the English language, and his bestselling novel, Contact, was turned into a major motion picture.

This review is from: Pale Blue Dot: A Vision of the Human Future in Space (Paperback)

There are two paperback editions of this book at Amazon. The 1995 edition contains the pictures that were so helpful (and entertaining) in the hardcover edition. The 1997 paperback edition has had the photographs removed. If you like beautiful astronomical photographs, order the 1995 edition.

Otherwise, the book is very enjoyable, and provides a cogent discussion of where Carl Sagan thinks we should aim our space program.

This review is from: Pale Blue Dot: A Vision of the Human Future in Space (Paperback)

I first read this book as a aimless 16-year old kid...now I'm an astrophysicist. It was Sagan's message of faith in science's role as mankind's candle in the dark, as well as his wonder for the universe that infected me, and spurred me to the path I'm on now. If you're not a religious fundamentalist and would like to open your mind to mankind's future in space as well as the wonders that await us in the cosmos, buy this book....or buy it for some teenager you know...

This review is from: Pale Blue Dot: A Vision of the Human Future in Space (Paperback)

As these pages attest, there are a number of fine writers out there providing us non-scientists with insights on nature's mysteries. None, however, quite reached the breadth of view or intensity of feeling imparted by Carl Sagan. His writings explained topics ranging from quantum particles to the extent of the cosmos. Along the way, he addressed evolution, space engineering and countless other facets of science and technology. Even fiction wasn't beyond his grasp.

Pale Blue Dot is a journey in time and space. Beginning with the assertion that we're natural wanderers, being the only species to settle across our world, it continues with a plea to extend further our exploration of space. The early chapters challenge restrictions on our desire to explore and learn. Sagan demonstrates how foolish minds have restrained our quest for knowledge of the cosmos. He then takes us on a tour of the solar system, exhibiting the wonders revealed by the fleet of robot probes. He reminds us of the forces the cosmos can unleash, sometimes right in our neighbourhood. Like many of the rest of us, Sagan was awed by the collision of a comet with the Jovian gas giant. It was a hint of what might lay in store for us if we fail to understand the universe better than we do now. The space probes also returned images of worlds invalidating existing theories of planetary formation. If our own neighbours can present such bizarre structures, what kinds of worlds ride beyond our ken, circling suns we can barely imagine? What Sagan can't portray, he can conjecture. With his firm working scientist's foundation, Sagan's speculations command respectful attention.

This book must be shelved alongside Richard Dawkins THE SELFISH GENE and THE BLIND WATCHMAKER. Together, these three fine works confront the traditional Western view of a universe and the life in it resulting from a Designer. From Dawkins' biological analysis to Sagan's cosmological view, this obstructionist outlook is here rendered groundless. More people must read Pale Blue Dot to gain an idea of who we are and where we stand in the vastness of a nearly limitless universe. Please read this book and convey its ideas to others. There is much to be gained from its imparted wisdom.
