On the Cosmic Horizon: Ten Great Mysteries for Third Millennium Astronomy (Mysteries for the New Millennium)
Share the wonder of the ten great mysteries of 21st century astronomy -- with an astronomer as your guide!*  Are we alone? What is the fate of the universe?*  Is the inflationary big bang theory true? What is the universe really made of?*  Compelling explanations for any educated reader -- even those with no science or math background!Outside of religion, no human pursuit deals with deeper questions of existence than astronomy, and few areas of science compare in capturing the public imagination. Today, however, the pace of discovery is so rapid that even professional astronomers have difficulty staying current. In this book, an astronomer and award-winning, highly acclaimed teacher shares the ten deepest mysteries that motivate astronomy today -- from the quest for life outside Earth, to the ultimate fate of the universe. It's an awesome collection of mysteries, and Jeffrey Bennett explains each one with remarkable clarity, enabling any educated citizen to share in the wonder, no matter how little scientific or mathematics background they may have. Is there life elsewhere in our solar system? Where are the Sun's missing neutrinos? What does the universe look like? How do galaxies evolve? Are Earth-like planets common? What makes gamma-ray bursts? Is the inflationary big bang theory true? What is the universe made out of -- and what is its fate? Every mystery is framed with a story that draws upon history or an especially resonant metaphor, then explained in detail,  but simply enough for those coming to astronomy for the first time.Jeffrey O. Bennett is Research Associate at the Center for Astrophysics and Space Astronomy in Boulder, CO, and holds a Ph.D. in Physics from the University of Colorado. As Visiting Senior Scientist at NASA, he guided the creation of NASA's Initiative to Develop Education through Astronomy (IDEA). Later, he led the creation of the Colorado Scale Model Solar System, a 1-to-10 billion scale model of the solar system; he is now co-leader of a project to build a similar scale model on the National Mall in Washington, DC, in a cooperative effort with the Smithsonian Institution, the Challenger Center, and NASA. He is author of two Addison Wesley books for non-scientists: The Cosmic Perspective and Using and Understanding Mathematics.
