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.

The riveting and mesmerizing story behind a watershed period in human history, the discovery of the startling size and true nature of our universe. On New Years Day in 1925, a young Edwin Hubble released his finding that our Universe was far bigger, eventually measured as a thousand trillion times larger than previously believed. Hubble’s proclamation sent shock waves through the scientific community. Six years later, in a series of meetings at Mount Wilson Observatory, Hubble and others convinced Albert Einstein that the Universe was not static but in fact expanding. Here Marcia Bartusiak reveals the key players, battles of will, clever insights, incredible technology, ground-breaking research, and wrong turns made by the early investigators of the heavens as they raced to uncover what many consider one of most significant discoveries in scientific history.

One of America's most talked-about science writers--and author of the award-winning book, Thursday's Universe--explores the phenomenon of "dark matter", the hypothesized, invisible substance that is changing our view of the universe. Photographs.

On October 1, 1958, the world's first civilian space agency opened for business as an emergency response to the Soviet Union's launch of Sputnik a year earlier. Within a decade, the National Aeronautics and Space Administration, universally known as NASA, had evolved from modest research teams experimenting with small converted rockets into one of the greatest technological and managerial enterprises ever known, capable of sending men to the moon aboard gigantic rockets and of dispatching robot explorers to Venus, Mars, and worlds far beyond. In spite of occasional, tragic setbacks in NASA's history, the Apollo lunar landing project remains a byword for American ingenuity; the winged space shuttles spearheaded the International Space Station and a dazzling array of astronomical satellites and robotic landers, and Earth observation programs have transformed our understanding of the cosmos and our home world's fragile place within it. Throughout NASA's 60-year history, images have played a central role. Who today is not familiar with the Hubble Space Telescope's mesmerizing views of the universe or the pin-sharp panoramas of Mars from NASA's surface rovers? And who could forget the photographs of the first men walking on the Moon?

“[A] glorious, pictorial tour of the universe . . . beginning with photos depicting Earth from space and progressing through . . . the individual planets.” —School Library Journal Preface by Bill Nye Take a tour of the universe with this breathtaking collection of photographs from the archives of NASA. Astonishing images of Earth from above, the phenomena of our solar system, and the celestial bodies of deep space will captivate readers and photography lovers with an interest in science, astronomy, and the great beyond. Each extraordinary photograph from the legendary space agency is paired with explanatory text that contextualizes its place in the cosmic ballet of planets, stars, dust, and matter—from Earth’s limb to solar flares, the Jellyfish Nebula to Pandora’s Cluster. Featuring a preface by Bill Nye, this engaging ebook offers up-close views of our remarkable cosmos, and sparks wonder at the marvels of Earth and space. “Delve into the great beyond with these awe-inspiring photos from NASA’s archive.” —Entertainment Weekly “Puts some of our most magnificent space imagery in context, and it’s enough to make anyone feel like just the tiniest little speck of stardust.” —BuzzFeed

"This is a truly astonishing book, invaluable for anyone with an interest in astronomy." Physics Bulletin "Just the thing for a first year university science course." Nature "This is a beautiful book in both concept and execution." Sky & Telescope

Acclaimed by Einstein himself, this is among the clearest, most readable expositions of relativity theory. It explains the problems Einstein faced, the experiments that led to his theories, and what his findings reveal about the forces that govern the universe. 1957 edition.

The theoretical physicist shares his latest thoughts on the nature of space and time in this anthology of selections from Princeton University Press. Along with eminent colleagues, Hawking extends theoretical frontiers by speculating on the big questions of modern cosmology.
