Amazon カスタマー: 日本語訳の「惑星へ」を読み、原文を読みたくなり購入しました。わかりやすく、引き込まれる文章です。日本語版より写真やイラストが豊富で、ページの中にちりばめられているのも魅力です。商品の説明にはハードがバーとありますが、表紙は柔らかいです。美術館の図録のような作りです。絶版のようで新刊は手に入らず、kindle版のみ。私のようなセーガンファンの年寄りは紙媒体で手元に置いておきたい1冊です。

KingInTheNorth: A very insightful read. A heavy astronomy book with layers of human philosophy.
Exploring the fragility of our current home and the possibilities of our strengths in not just the near future, but eons ahead.

Sumana p.: The book itself is very good due to its content, but the quality of the cover or paper is not good , it seemed to be duplicate copy of the real book. I bought it for 671rs and still didn't get decent quality product.

Charles Sherry: Dr Sagan goes into great detail of the four billion years existence of our planet from creation to the future possibilities of great danger and as a stepping stone to establishment of other places of human habitation. An interesting discussion of how religions and their books are outpaced with the speed of science and astrological discoveries.

Stefan: Pale Blue Dot is a non-fiction and is Sagan’s analysis of the role space will play in humanity’s future. It was written in 1994, and therefore one of his last publications, as Sagan tragically died in 1996. The title of the book, Pale Blue Dot, was taken from the instantly infamous Pale Blue Dot photograph taken by Voyager 1 in 1990. In his book, Sagan created a short analysis of the importance of the human exploration of space. His reasons range from spin-off technology to the intrinsic value of exploration and discovery. But what struck me the most about Sagan’s book was that although he talked extensively about these as, in general, good reasons to explore space, they weren’t the best reason. Or rather, they weren’t enough. Sagan goes on to argue that the single greatest reason to explore space is the survival of the species. Something as an individual I haven't ever really thought of. It is possible that we could destroy ourselves through nuclear war, yes, but that’s not the survival Sagan is talking about. He’s speaking about asteroids. There is a chance that at some point in the future a rock big enough to destroy human life will collide with Earth. Exploring...

Thomas Erickson: I've read many of Carl Sagan's books and most are 5 stars (see my reviews). Here is another great book.

Carl was able to go through a technical topic in a vast time line for the average layman to understand. He was a master at this.The Pale Blue Dot reads very well and INMO no boring parts. The reader wants to read on.

The reader learns the "wanderers"...planets)our ancient ancestors knew. We see the progression of an Earth centered belief to a Sun centered belief, then to maybe our galaxy is the center of the universe to a total no center in the universe. Then possible many universes. He shows the various astronomers like Galileo, Copernicus and many more that helped shape our understanding of the Cosmos and the sometimes persecution they had to endure.

Excellent photos of different planets, galaxies and stars. Also different spaceships from man's earliest to future ION powered craft.
Carl gives new packages of knowledge for many different aspects of science, philosophy, physics and other human studies.Also a very interesting discussion of Near earth asteroids and comets and the potential of a catastrophic life ending collision. There is a discussion on...

John Dexter: Carl Sagan viewed space exploration as both a natural consequence of our nomadic past and an essential constituent of our survival: in Pale Blue Dot, he articulates this vision, making an elegant and compelling argument for a programme of sustained space-exploration in order to cheat the cosmos of humanity's ultimate extinction.

Given Sagan's prodigious output over an all too brief life, recycled material from earlier work is to be expected and the book opens with one of his recurrent themes, revisiting the idea that science continues to diminish humanity's over-inflated sense of importance and plots our species' ignominious ("great" ch.3 pp.20-37) demotion from cosmic "purpose" to universal bit part. Sagan also covers other favourite topics, including global warming and weapons of mass destruction, synthesising these themes into a comprehensive argument that humanity has reached a turning point in its evolution with the ability for self-destruction without, perhaps, the wisdom to prevent it. However, whilst some of the early content may feel familiar, this is not a simple rehashing of old arguments: it is a grand vision of humanity's future and, with his characteristic...
