J. Richard Gott was among the first cosmologists to propose that the structure of our universe is like a sponge made up of clusters of galaxies intricately connected by filaments of galaxies--a magnificent structure now called the "cosmic web" and mapped extensively by teams of astronomers. Here is his gripping insider's account of how a generation of undaunted theorists and observers solved the mystery of the architecture of our cosmos.

The Cosmic Web begins with modern pioneers of extragalactic astronomy, such as Edwin Hubble and Fritz Zwicky. It goes on to describe how,...

The theory of relativity reveals the speed of light as the cosmic speed limit, the mind-bending ideas of time dilation and curvature of...

From the authors of Sketching the Moon comes a comprehensive guide filled with richly illustrated, detailed drawing tutorials that cover a variety of solar phenomena. Explanations of what to expect visually from white light, Hydrogen-alpha and Calcium K filters are provided for those new to solar observing, along with essential tips on equipment, observing techniques and the practicalities of drawing at the eyepiece. Time-honored, traditional methods and media are described in tandem with innovative techniques developed and shared by contemporary astronomical sketchers. For the...

This book presents an overview of the current understanding of gravitation, with a focus on the current efforts to test its theory, especially general relativity. It shows how the quest for a deeper theory, which would possibly incorporate gravity in the quantum realm, is more than ever an open field.

The majority of the contributions deals with the manifold facets of experimental gravitation, but the book goes beyond this and covers a broad range of subjects from the foundations of gravitational theories to astrophysics and cosmology.

The book is divided into three parts. The...

This book captures the complex world of planetary moons, which are more diverse than Earth's sole satellite might lead you to believe. New missions continue to find more of these planetary satellites, making an up to date guide more necessary than ever. Why do Mercury and Venus have no moons at all? Earth's Moon, of course, is covered in the book with highly detailed maps. Then we move outward to the moons of Mars, then on to many of the more notable asteroid moons, and finally to a list of less-notable ones.

All the major moons of the gas giant planets are covered in great detail,...

Sometime in the not-too-distant future ... unbeknownst to Earth, the Galaxy is home to a number of spacefaring societies. This confederation enforces a strict protocol forbidding any contact with civilizations that have not yet achieved both a substantial spacefaring capability and sufficient maturity to control the technology explosion before triggering their own extinction.

While this policy is intended to only bring in peaceful new members, matters change entirely when the confederation is threatened by some unknown entity - is the menace real or imagined? The confederation...

The book is based on research presentations at the international conference, "Emerging Trends in Applied Mathematics: In the Memory of Sir Asutosh Mookerjee, S.N. Bose, M.N. Saha and N.R. Sen," held at the Department of Applied Mathematics, University of Calcutta, during 12-14 February 2014. It focuses on various emerging and challenging topics in the field of applied mathematics and theoretical physics. The book will be a valuable resource for postgraduate students at higher levels and researchers in applied mathematics and theoretical physics.

Researchers presented a wide variety...

This book is for anyone who owns, or is thinking of owning, a Vixen Star Book Ten telescope mount or its predecessor. A revolution in amateur astronomy has occurred in the past decade with the wide availability of high tech, computer-driven, Go-To telescopes. Vixen Optics is leading the way by offering the Star Book Ten system, with its unique star map graphics software. The Star Book Ten is the latest version of computer telescope control using star map graphics as a user interface, first introduced in the original Star Book first offered in 2003.

The increasingly complicated...

MOMENTUM IS BUILDING for a return to the Moon. NASA's international partners on the International Space Station are in favor of returning to the lunar surface, as are India and China. The horizon goal may be Mars, but the political, funding and the technological and medical infeasibility of such an objective means the next logical step is a return to the Moon. While much has been learned about the Moon over the years, we don't understand its resource wealth potential and the technologies to exploit those resources have yet to be developed, but there are a number of companies that are...

When observing the sky on a very clear, dark night, the soft glow of the Milky Way with its thousands of stars can be seen with the naked eye. Over the centuries since Galileo Galilei first pointed a telescope at the galaxy in 1609, this awe-inspiring yet easily visible panorama was our cosmos, our celestial world. With each new scientific discovery, however, this cosmos has grown dramatically, increasing rapidly over the last several decades. As we look deeper into space, the earlier phases of the cosmos are unveiled to us, but we know that even with the largest telescopes, we will see...

Observers no longer need to wonder what they will turn their attention to each night of the year with this updated text of a beloved favorite from Sir Partick Moore. His night-by-night account of the stars is the best possible guide an observer could ask for, and now includes the latest data for the years 2015-2020, preserving and extending Sir Patrick Moore's legacy.

This new edition of his classic text makes it easy to see why Sir Patrick Moore was such a helpful guide to generations of budding astronomers, professional and amateur alike. For every night of the year Patrick gives...
