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 cosmos―in 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.

本书将带你踏上可观测宇宙的宏伟之旅，引导你在令人惊叹的3D宇宙中欣赏最壮观的景象。本书展示了一系列丰富的立体彩色图像，可以使用一个特殊的立体观察器以3D方式观看，该观察器可以轻松地从书的封面上折叠出来，本书展示了你从未见过的宇宙环境。天文学是关于人类如何从对天空的二维圆顶的感知发展到对不断扩大的三维宇宙的更深入理解的故事。本书邀请你参与这个故事，深入探索由先进的天文研究和观测所揭示的宇宙。你将从月球穿越太阳系，到系外行星、遥远的星云和星系团，直到最后到达宇宙微波背景辐射（或称CMB），这是我们能观察到的最遥远的光。与这些天体奇迹的距离从1.3光秒到138亿光年不等。一路上，作者解释了你所看到的东西的迷人特征，包括3D图像是如何使用早期天文学家设计的测量空间物体距离的相同技术制作的。书中引人注目的3D图像将使你感到惊讶，将你的视野延伸到宇宙的最远处。你将以一种非常独特的方式仰望夜空。
