Book excerpt: Have you ever wondered what comets are and why astronomers spend so much time studying them? Now, a comet expert and an astronomical historian have come together to produce this unique book. Using their several decades of teaching experience, the authors have concisely presented the information you need to comprehend these majestic apparitions that grace our night skies. No mathematical proficiency is needed. In fact, this book doesn't contain a single equation. Comets are cosmic Rosetta stones, bridging our current knowledge by digging back to the earliest days of our solar systems. How did life arise on Earth? Did comets play a significant role in bringing water and the necessary organic matter to our early Earth? How about the dinosaurs? Were they driven to extinction by a cometary impact 66 million years ago? Comets may be both the enablers and destroyers of life on Earth as we know it. These are some of the tantalizing questions discussed here. If you so desire, steps are given to join the ranks of amateur comet hunters. Astronomy is one of the last sciences where amateurs play a significant role. Your reward for discovery? A comet officially bearing your name in the history books. The next great comet is on its way, we just do not know when it will arrive. Armed with this book, you will be ready to enjoy this unforgettable event.

Book excerpt: How did a company best known for its glass jars hit a comet 83 million miles away? The answer involves technical expertise, heroic dedication, an industrial giant’s push to modernize, Hitler’s V-2 rocket, speakers destined for a Hall & Oates summer concert tour, and the search for life’s origins. In “From Jars to the Stars: How Ball Came to Build a Comet-Hunting Machine,” award-winning science journalist Todd Neff presents an inside look at the backgrounds and motivations of the men and women who actually create the spacecraft on which the American space program rides. A timeless story of science, engineering, politics and business strategy intertwining to bring success in the brutal business of space, “From Jars to the Stars” is a lively account of one of mankind’s great modern achievements. It is a story about people, foremost those on the Deep Impact mission, which smashed a spacecraft into the comet Tempel 1. “From Jars to the Stars” explores the improbable beginnings of Ball Aerospace & Technologies Corp., which built the comet hunter, and the evolution of the American space agency that funded it. The book begins with the story of a group of University of Colorado students who built a “sun seeker” for the noses of sounding rockets studying the home star. The pathbreaking device sparked the creation and development of both Ball Aerospace and the University of Colorado’s formidable Laboratory for Atmospheric and Space Physics. “From Jars to the Stars” describes how Ed Ball, president of the Ball Brothers Company of Muncie, Indiana, ended up owning a space business in Boulder, Colorado, through a combination of strategic intent and serendipity. Neff explores the personalities and the technologies behind Ball’s pioneering spacecraft, the Orbiting Solar Observatory launched in 1962. The Ball orbiter prepares the ground for Deep Impact, showing readers how much—and how little—changed across four decades of American space exploration. Neff goes on to show how Ball Aerospace evolved into an organization capable of building seven Hubble Space Telescope instruments as well as the comet hunter at the center of the story. The author describes the development of the American space enterprise as it went from emphasizing big-budget “gigabuck” missions to “faster, better, cheaper” spacecraft of the sort Ball specialized in. Neff pays special mind to NASA’s Jet Propulsion Laboratory, the world leader in interplanetary space exploration and Ball’s partner on Deep Impact. It was often a rocky marriage. Throughout, Neff makes clear that robotic space missions are indeed manned: the people just happen to stay on the ground.

Download or read book Statius Thebaid VII written by J.J.L. Smolenaars and published by BRILL. This book was released on 2018-07-17 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: The epic poem the Thebaid by P. Papinius Statius, written about AD 80 to 92, deals with the fraternal strife between Oedipus' sons Eteocles and Polynices for the mastery of Thebes. Book VII describes the forced march of the Seven and their arrival at Thebes, Jocasta's vain attempt at mediation and Amphiaraus' spectacular katabasis. This book is the first which deals with Thebaid VII since Barth (1664) and Amar & Lemaire (1825-30). Apart from being a commentary in the philological sense, it examines in close detail the poet's mannered style and analyses the text as a system of intertextual references. In addition to Homer and Vergil, specific passages from Euripides, Lucan, Seneca and especially Valerius Flaccus were exploited by Statius to create his challenging imitation. The identification of these sources offers the key to interpret and evaluate the poet's artistic intentions. The Introduction discusses Statius' technique of multiple imitation. The information brought together has been made easily accessible by full indexes and an appendix listing the passages imitated by Statius.

Download or read book Physics and Chemistry of Comets written by Walter F. Huebner and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: As this excellent book demonstrates, the study of comets has now reached the fas cinating stage where we understand comets in general simple tenns while, at the same time, we are uncertain about practically all the details of cometary nature, structure, processes, and origin. In every aspect, even including dynamics, a choice among several or many competing theories is made impossible simply by the lack of detailed knowledge. The space missions, snapshot studies of two comets, partic ularly the one that immortalizes the name of Sir Edmund Halley, have produced a huge mass of valuable new infonnation and a number of surprises. Nonetheless, we face the tantalizing realization that we have obtained only a fleeting glance at two of perhaps a hundred billion (lOll) or more comets with possibly differing natures, origins, and physical histories. To my personal satisfaction, comets seem to have discrete nuclei made up of dirty snowballs, as I concluded four decades ago, but perhaps they are more like frozen rubbish piles.

Download or read book Near Earth Objects written by Donald K. Yeomans and published by Princeton University Press. This book was released on 2016-11-08 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: An insider's look at the science of near-Earth comets and asteroids Of all the natural disasters that could befall us, only an Earth impact by a large comet or asteroid has the potential to end civilization in a single blow. Yet these near-Earth objects also offer tantalizing clues to our solar system's origins, and someday could even serve as stepping-stones for space exploration. In this book, Donald Yeomans introduces readers to the science of near-Earth objects—its history, applications, and ongoing quest to find near-Earth objects before they find us. In its course around the sun, the Earth passes through a veritable shooting gallery of millions of nearby comets and asteroids. One such asteroid is thought to have plunged into our planet sixty-five million years ago, triggering a global catastrophe that killed off the dinosaurs. Yeomans provides an up-to-date and accessible guide for understanding the threats posed by near-Earth objects, and also explains how early collisions with them delivered the ingredients that made life on Earth possible. He shows how later impacts spurred evolution, allowing only the most adaptable species to thrive—in fact, we humans may owe our very existence to objects that struck our planet. Yeomans takes readers behind the scenes of today’s efforts to find, track, and study near-Earth objects. He shows how the same comets and asteroids most likely to collide with us could also be mined for precious natural resources like water and oxygen, and used as watering holes and fueling stations for expeditions to Mars and the outermost reaches of our solar system.
