A lavish coffee-table book featuring spectacular images from the Chandra X-Ray Observatory, the most powerful X-Ray telescope ever built
Take a journey through the cosmos with Light from the Void, a stunning collection of photographs from the Chandra X-Ray Observatory's two decades of operation. The book showcases rarely-seen celestial phenomena such as black holes, planetary nebulae, galaxy clusters, gravitational waves, stellar birth and death, and more. Accompanying these images of incredible natural phenomena are captions explaining how they occur. The images start close to home and move outward: beginning with images of the Chandra launch, then moving into the solar system, through the nearby universe, and finally to the most distant galaxies Chandra has observed, the book brings readers on a far-out visual voyage.

The Ballet of the Planets unravels the beautiful mystery of planetary motion, revealing how our understanding of astronomy evolved from Archimedes and Ptolemy to Copernicus, Kepler, and Newton. Mathematician Donald Benson shows that ancient theories of planetary motion were based on the assumptions that the Earth was the center of the universe and the planets moved in a uniform circular motion.
Since ancient astronomers noted that occasionally a planet would exhibit retrograde motion--would seem to reverse its direction and move briefly westward--they concluded that the planets moved in epicyclic curves, circles with smaller interior loops, similar to the patterns of a child's Spirograph. With the coming of the Copernican revolution, the retrograde motion was seen to be apparent rather than real, leading to the idea that the planets moved in ellipses. This laid the ground for Newton's great achievement--integrating the concepts of astronomy and mechanics--which revealed not only how the planets moved, but also why. Throughout, Benson focuses on naked-eye astronomy, which makes it easy for the novice to grasp the work of these pioneers of astronomy.
