"Welcome to the Universe in 3D, the ideal gift for star gazers of all ages, brings readers a built-in stereo viewer...that enables a 3D tour of the universe. Armchair astronomers can peer through the stereo viewer, page through nearly 60 double images of the solar system and take in three-dimensional images from as far away as 13.8 billion light years .... Cheaper than a telescope, this is a marvelous introduction to astronomy"

"If you go out and simply look up, everything - from the Moon to the planets to the stars to the band of the Milky Way - appears to be pasted on the two-dimensional surface of the dome of the sky. Yet, the story of astronomy as a science is how, over time, astronomers have discovered the cosmos in depth. It is the story of the measurement of position and distance, and how our 2D view of the sky above us evolved into a more sophisticated comprehension of the real 3D depths of space. The distances to the stars were first measured using the parallax effect - that is, by comparing the view from opposite sides of the Earth's orbit. This is the same effect that your brain uses (comparing the views from your left and right eyes) to effortlessly give you depth perception. In this book, the authors present the most spectacular stereo images available in astronomy. (Stereo images are pairs of images of the same object, taken 6 months apart - which, as the Earth turns, means viewed from opposite sides of the Earth's orbit.) Each pair of stereo images, when viewed with a special stereo viewer (to be contained in the book itself), portrays the object in 3D. Each striking 3D picture is accompanied by a caption on the facing page, which tells the story and significance of the image in a mini-essay and points out its interesting features. Rather than a random assortment of astronomical wonders, the pictures are arranged in order of their distance from Earth. The book starts out with the Moon and moves outward through planets, stars, and galaxies, finally reaching the cosmic microwave background radiation (CMB), the most distant thing we can see. The distances of objects are given in light travel times - from 1.3 light-seconds for the Moon to 13.8 billion light-years for the CMB. These distances, along with highlights of how each object was discovered and measured by astronomers, provide a framework and narrative thread for the book, which is carried forward from one caption to the next. At each stage of this outward journey, the reader will learn new and surprising facts about fascinating objects in the depths of space. The book also features an introductory Preface that outlines the story of the discovery of the universe in depth, describes the parallax effect, and provides the background and context for the forthcoming visual tour of the observable universe in 3D"--

Résumé

**New York Times bestseller
Journey into the universe through the most spectacular sights in astronomy in stereoscopic 3D

Welcome to the Universe in 3D takes you on a grand tour of the observable universe, guiding you through the most spectacular sights in the cosmosin breathtaking 3D. Presenting a rich array of stereoscopic color images, which can be viewed in 3D using a special stereo viewer that folds easily out of the cover of the book, this book reveals your cosmic environment as you have never seen it before.

Astronomy is the story of how humankind's perception of the two-dimensional dome of the sky evolved into a far deeper comprehension of an expanding three-dimensional cosmos. This book invites you to take part in this story by exploring the universe in depth, as revealed by cutting-edge astronomical research and observations. You will journey from the Moon through the solar system, out to exoplanets, distant nebulas, and galaxy clusters, until you finally reach the cosmic microwave background radiation (or CMB), the most distant light we can observe. The distances to these celestial wonders range from 1.3 light-seconds to 13.8 billion light-years. Along the way, the authors explain the fascinating features of what you are seeing, including how the 3D images were made using the same technique that early astronomers devised to measure distances to objects in space.

The dramatic 3D images in this one-of-a-kind book will astonish you, extending your vision out to the farthest reaches of the universe. You will never look up into the night sky the same way again.
