Pale Blue Dot: A Vision of the Human Future in Space by Carl Sagan (Audio Book and E-Book)

October 3, 2008

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.

Billions & Billions: Thoughts on Life and Death at the Brink of the Millennium by Carl Sagan (E-Book)

October 1, 2008

From Library Journal
It is doubtful that there is anyone unfamiliar with noted astronomer and science writer Sagan’s ability to convey the wonder, excitement, and joy of science. This book is a wonderful, if eclectic, collection of essays, some reprinted from magazines of national prominence, covering a wide range of topics: the invention of chess, life on Mars, global warming, abortion, international affairs, the nature of government, and the meaning of morality. Writing with clarity and an understanding of human nature, Sagan offers hope for humanity’s future as he illuminates our ability to understand ourselves and to change the world for the better. The last chapter is an account of his struggle with myelodysplasia, the illness that finally took his life in December 1996. An epilog written by his wife is a personal account of the man rather than the scientist admired by so many. This last book is a fitting capstone to a distinguished career. Enthusiastically recommended.
