The search -- Discoveries -- Observation -- Detection, recognition, and classification of cosmic phenomena -- The fringes of legitimacy : the need for enlightened planning.

For many millennia the starry night sky has been a source of wonder and awe to men and women who have tried to unravel the mystery of the billion distant lights that fill the heavens after dark. The story of the great discoverers who succeeded in explaining part of the mystery is told here with the joy and infectious enthusiasm that only a fellow discoverer can convey. David Levy, codiscoverer of Comet Shoemaker-Levy 9, with his wife, Wendee Wallach-Levy, evokes that marvelous moment of Eureka! as he masterfully relates each story. He gives the reader a glimpse of the enthralling adventure of cosmic discovery through stories of the most famous and brilliant astronomers. Beyond their personal accomplishments, these scientists expanded all of humanity's understanding of the universe and our place within it.For example, Galileo's breathtaking discovery of the moons of Jupiter, new worlds that refused to orbit the sun, challenged the whole doctrine of the earth being the center of the universe. With the start of the 20th century, Shapley pushed back the envelope that had been opened by Galileo by proving that the center of our galaxy is very far beyond our own sun. And Hubble showed that even our galaxy is but a tiny part of a universe that is rapidly expanding. In describing these milestones of science, Levy reveals his own spirited conversations with such luminaries of the imagination as the discoverer of the planet Pluto, Clyde Tombaugh, and one of the world's greatest science fiction writers, Sir Arthur C. Clarke.Through Levy's unique perspective on cosmic discovery, he is able to connect his own personal life story with that of astronomers of the past and by extension with the history of the whole universe. As the codiscoverer of the spectacular comet that crashed into Jupiter, Levy formulated a whole new range of exciting questions about the universe: Do comets serve to transport the elements of life from one planet to the next? What is the evidence that a large comet once hit the earth? Will the earth someday be in danger of colliding with another such comet and will we have the technology to stop it?This fascinating book will excite any of us who have stared at the night sky in awe and amazement.David Levy and Wendee Wallach-Levy (Vail, AZ) are continuing their ongoing search for new comets. David Levy is the president of the Jarnac Observatory, science editor for PARADE magazine, a contributing editor to Sky and Telescope and Sky News magazines, and the author of Starry Nights, The Quest for Comets, and Impact Jupiter, among other books.

In a simple manner, explains the frontiers of astronomy, how fractals appear in cosmic physics, offers a personal view of the history of the idea of self-similarity and of cosmological principles and presents the debate which illustrates how new concepts and deeper observations reveal unexpected aspects of Nature.

An unparalleled history of astronomy presented in the words of the scientists who made the discoveries. Here are the writings of Copernicus, Galileo, Kepler, Newton, Halley, Hubble, and Einstein, as well as that of dozens of others who have significantly contributed to our picture of the universe. From Aristotle's proof that the Earth is round to the 1998 paper that posited an accelerating universe, this book contains 100 entries spanning the history of astronomy. Award-winning science writer Marcia Bartusiak provides enormously entertaining introductions, putting the material in context and explaining its place in the literature. Archives of the Universe is essential reading for professional astronomers, science history buffs, and backyard stargazers alike.

How did our universe come to exist? Why do stars shine? Is there life beyond the Earth? For millennia, humans have looked to the celestial sphere to explain the cosmos,first recording the movements of the Moon 25,000 years ago. Since the Enlightenmentand the dawn of the space age, scientists have been unravelling cosmic mysteries, andraising astonishing new questions for future generations to answer. Today we live inan age of unprecedented astronomical revelation, from the discovery of water on Marsto the detection of gravitational waves and the first photograph of a black hole. World-renowned astronomer Paul Murdin explains the science behind these discoveries, along with the passions, strugglesand quirks of fate that made them some of the most intriguing dramas of their times,demonstrating how human ingenuity and technological innovation have expandedour knowledge of the Universe beyond anything our ancestors - even as recently asa generation ago - could ever have imagined.

World-leading researchers, including Nobel Laureates, explore the most basic questions of science, philosophy, and the nature of existence.
