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.

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.

I understand the thinking behind releasing a new digital conversion of the original masters as they are now, with silences contained within the degraded tapes. But, I would have much preferred the previous audio book release sound files, lower fidelity as it may be, to have been spliced in where there is silence. In this release, entire paragraphs are unintelligible from the tape degradation.
I am not sure why the previous audio book version is not able to be purchased, whether it's due to copyright or licensing or some other absurd reason. That is the version I would like to get my hands on.
I do not regret purchasing this, as it supports Druyan and the Sagan estate, but I don't think I will be using it much.
It is a wonderful book about mankind’s future in space travel and the wonders of the universe. I have a large collection of books and my grandsons often come over and borrow them. Some I have duplicate copies of and I freely share them with my family. This is one of those books that will be passed along to my grandsons and great grandsons.
Sagan had an open and inquisitive mind and he always wanted to imagine and study and learn. This is the type of book that inspired future scientist and generations to come to excel and explore our universe. It is worth passing onto the next generation. This book is one of my favorites.
