Black holes are the best-known and least-understood objects in the universe. In Einstein's Monsters, distinguished astronomer Chris Impey takes readers on a vivid tour of these enigmatic giants. He weaves a fascinating tale out of the fiendishly complex math of black holes and the colorful history of their discovery. Impey blends this history with a poignant account of the phenomena scientists have witnessed while observing black holes: stars swarming like bees around the center of our galaxy; black holes performing gravitational waltzes with visible stars; the cymbal clash of two black holes colliding, releasing ripples in space time. Clear, compelling, and profound, Einstein's Monsters reveals how our comprehension of black holes is intrinsically linked to how we make sense of the universe and our place within it.
Through a Universe Darkly: A Cosmic Tale of Ancient Ethers, Dark Matter, and the Fate of the Universe
With 250,000 copies in print since its initial publication in 1983, NightWatch has become a standard reference guide for stargazers throughout North America.
The new Third Edition expands on that success with a completely revised and updated text, more than 100 new color photos and diagrams and 16 additional pages that cover such! new astronomical pursuits as computerized telescopes, reviews of new telescope designs and accessories, and astronomy on the Internet.
All charts, tables and diagrams have been updated and, in some cases, redesigned for easier use. Improved spacecraft measurements of the distances to the stars (recently released by the European Space Agency) are included in the charts, along with additional observing tips for stargazers using binoculars and telescopes. An expanded chapter on Astrophotography lists the best modern films and cameras for skyshooting.
The new NightWatch is faithful to the "ultra-simplified, no jargon" philosophy of the original, and at the same time, offers substantially more practical information for the novice and intermediate-level amateur astronomer. The Royal Astronomical Society of Canada called the first edition "the best of its kind"- the new Third Edition is better still. It is still an abundantly illustrated, wide-sized volume designed for easy reference during many starlit nights.
More than 2,000 years ago, Eratosthenes, in Alexandria, used a stick, a hole in the ground, sunllght at summer solstice, and elementary geometry to measure the circumference of the Earth with surprising accuracy, long before anyone was able to circumnavigate it. Today, scientists are attempting to measure the entire universe and to determine its origin. Although the methods have changed, the quest to chart the horizons of space and time continues to be one of the great adventures of science.
Measuring the Universe is an eloquent chronicle of the men and women- from Aristarchus to Cassini, Sir Isaac Newton to Henrietta Leavitt and Stephen Hawking-who have gradually unlocked the mysteries of "how far" and in so doing have changed our ideas about the size and nature of the universe and our place in it. Kitty Ferguson reveals their methods to have been as inventive as their results were-and are-eye-opening. Advances such as Copernicus's revolutionary insights about the arrangement of the solar system, William Herschel's meticulous creation of the first three-dimensional map of the universe, and Edwin Hubble's astonishing discovery that the universe is expanding have by turns revolutionized our concept of the universe. Connecting centuries of breakthroughs with the political and cultural events surrounding them, Ferguson makes astronomy part of the sweep of history.
To measure the seemingly immeasurable, scientists have always pushed the boundaries of the imagination-today, for example, facing the paradox of an ever-expanding universe that doesn't appear to expand into anything. In Kitty Fergeson's skillfill hands, the unimaginable becomes accessible and the splendid quest something we all can share.
This collective knowledge, prepared by a team of more than one hundred international authorities on asteroids, includes new insights into asteroid-meteorite connections, possible relationships with comets, and the hazards posed by asteroids colliding with Earth. The book's contents include reports on surveys based on remote observation and summaries of physical properties; results of in situ exploration; studies of dynamical, collisional, cosmochemical, and weathering evolutionary processes; and discussions of asteroid families and the relationships between asteroids and other solar system bodies. Two previous Space Science Series volumes have established standards for research into asteroids. Asteroids III carries that tradition forward in a book that will stand as the definitive source on its subject for the next decade.
Every organism on Earth responds to four major cycles: the solar and lunar day, the synodic month and the year. We all dance to these primary rhythms. This book reveals the poetic cosmology that lies within the cycles of the Sun and Moon as seen from the Earth.
Throughout time, the moon has spoken to poets, philosophers, and astrologers, and its ever-changing image has been captured by artists from all cultures and periods. Illustrated with Renaissance frescoes, Tlingit masks, Chinese architecture, nature photography, and icons of popular culture, The Moon includes Persian court poetry, Shakespearean verse, and provocative words of wisdom from Native American tradition. Elegant and evocative, this volume of lore and legend will be treasured by all readers.
