Published more than two decades ago to great critical acclaim and commercial success, A Brief History of Time has become a landmark volume in science writing. Stephen Hawking, one of the great minds of our time, explores such profound questions as: How did the universe begin--and what made its start possible? Does time always flow forward? Is the universe unending--or are there boundaries? Are there other dimensions in space? What will happen when it all ends?

Told in language we all can understand, A Brief History of Time...

Recent astronomical observations indicate that a black hole is approaching our solar system. Although the black hole will pass more distant than the orbit of Saturn, its gravity will slightly change the Earth's orbit. The year will become 378 days long. During winter it will be 6% closer to the sun and during...

Every night, astronomers use a new generation of giant telescopes at observatories around the world to study phenomena at the forefront of science. By focusing on the history of the Gemini Observatory--twin 8-meter telescopes located on mountain peaks in Hawaii and Chile--Giant Telescopes tells the story behind the planning and construction of modern scientific tools, offering a detailed view of the technological and political transformation of astronomy in the postwar era.

Drawing on interviews with participants and archival documents, W. Patrick McCray describes the...

The Dutch telescope and the Italian scientist Galileo have long enjoyed a durable connection in the popular mind--so much so that it seems this simple glass instrument transformed a rather modest middle-aged scholar into the bold icon of the Copernican Revolution. And yet the extraordinary speed with which the telescope changed the course of Galileo's life and early modern astronomy obscures the astronomer's own curiously delayed encounter with the instrument. This book considers the lapse between the telescope's creation in The Hague in 1608 and Galileo's alleged acquaintance with...
