Join Bonnie J. Buratti, a leading planetary astronomer, on this personal tour of NASA's latest discoveries. Moving through the Solar System from Mercury, Venus, Mars, past comets and asteroids and the moons of the giant planets, to Pluto, and on to exoplanets, she gives vivid descriptions of landforms that are similar to those found on Earth but that are more fantastic. Sulfur-rich volcanoes and lakes on Io, active gullies on Mars, huge ice plumes and tar-like deposits on the moons of Saturn, hydrocarbon rivers and lakes on Titan, and nitrogen glaciers on Pluto are just some of the marvels that await readers. Discover what it is like to be involved in a major scientific enterprise, with all its pitfalls and excitement, from the perspective of a female scientist. This engaging account of modern space exploration is written for non-specialist readers, from students in high school to enthusiasts of all ages.

In their trenchant panoramic overview - ranging from antiquity to the present-day - John and Anna Rist write with authority and ennui about nothing less than the loss of the foundational culture of the West. The authors characterize this culture as the 'original tradition', viewing its erosion as one which has led to anxiety about the entire value of Western thought. The causes of the disintegration are discussed with an intensity rare in academe. Critics of modernity ordinarily concentrate on the Enlightenment and the book certainly offers deep analysis of Enlightenment thought. But it goes further. Thus the cruelty of modern totalitarianism is now depicted as in the spirit of the French Revolution and its implacable hostility to a vanished primordial heritage, while scientism, bureaucracy and consumerism appear as the only rivals to a threatening nihilism. The book argues that Western thought has created a set of conflicting moral and spiritual customs: to the detriment of coherence, in individual minds as in society and culture.
