Review
"David Eicher has more than three decades' experience of writing about astronomy for a general readership. His experience and enthusiasm shine through in this wide-ranging survey of current 'hot topics'."
Martin Rees, Emeritus Professor of Cosmology and Astrophysics, University of Cambridge
"The New Cosmos by David Eicher is a wonderful read! This wonderfully written, accessible, authoritative new book spans the breadth of major topics in early twenty-first-century astronomy, engaging the reader in every chapter. I haven't seen a better book surveying modern astronomy in a decade. I highly recommend this masterpiece as a gift to yourself or anyone interested in space and astronomy."
Alan Stern, Principal Investigator of the New Horizons mission, Southwest Research Institute
"If you are looking for a collection of newspaper headlines full of hype about this discovery or that, then The New Cosmos probably isn't for you. On the other hand, if those headlines whet your appetite for something more substantial, then pick up a copy and settle in for a fascinating and enlightening read. The New Cosmos is not simply a survey of astronomy and planetary science - it is more of a travelogue, starting with intriguing questions and then following where each story leads. And there throughout the journey is David J. Eicher's obvious passion and joy for the wonders of the heavens, and for the human quest to make those wonders known."
Jeff Hester, Professor Emeritus, School of Earth and Space Exploration, Arizona State University
"In this book, Eicher synthesizes a wealth of relatively new information into an interesting, coherent, up-to-date overview of many of the most important and exciting areas of astronomy ... Immersing yourself in the chapters that follow will give you a new sense of wonder at the amazing universe that we inhabit, yet simultaneously awakening both your humility as a cosmic speck of dust and your awe at our present understanding of the cosmos."
Alex Filippenko, University of California, Berkeley, from the Foreword
"This is an exceptional book that places our life in a global perspective on the cosmic stage, both in space and in time. It leaves you wondering whether our civilization should reconsider its priorities if it wishes to be regarded as intelligent."
Abraham Loeb, Harvard University
"David Eicher provides a much-needed update to Carl Sagan's classic book Cosmos from thirty-five years ago, describing the most fascinating advances in astronomy and planetary science."
Alfred McEwen, Lunar and Planetary Laboratory, University of Arizona, Tucson
"The New Cosmos is an enjoyable stroll through our current knowledge of the objects in the cosmic zoo. As a planetary scientist, I welcome the opportunity to learn about fields distant from my own. I know that I can trust their treatment because my own field is expertly and concisely covered. Bravo!"
Paul D. Spudis, Lunar and Planetary Institute, Houston
"It can be easy to forget just how many different major astrophysical discoveries have taken place in recent years. Eicher takes the reader through a whirlwind tour of the most exciting highlights, from newly discovered planets in our own cosmic backyard, to the dark matter and dark energy that are ubiquitous throughout our universe. The New Cosmos covers all of the 'big questions' that are being nervously and excitedly debated in the hallways of astronomy and physics departments around the world."
Dan Hooper, Fermilab, Illinois
"If you want to know what happens when the Sun dies, or wish to understand such puzzles as the true nature of black holes and the long-term fate of the universe, then you should be reading this book. In clear and authoritative prose, David Eicher offers readers a wonderful set of answers to the most consequential questions in astronomy. It's an impressively comprehensive treatment of the biggest subject of all - the cosmos."
Seth Shostak, SETI Institute, California

This book will get you up to date in astronomy...
By Amazon Customer
I have been a subscriber to Astronomy Magazine and have a decent library of astronomy and physics books, so I am not without material to keep me busy. This work from Eicher is the latest, and best, addition to that library. The book is meant to be a survey of today's hottest and most media-driven topics in Astronomy and Cosmology, all wrapped up into one source. Its success comes not only from how thoroughly Eicher treats each subject, but how readable it is for the average person. Alex Fillipenko's introduction is a superb primer, and the rest is an entertaining orientation to the hot picks of today's research, the lives of stars, our Solar System (including poor Pluto), and on and on until you're caught up to the state of the science in 2015, and invited with open arms to keep moving forward with a solid knowledge of what we know now. In summary, consider this book a nice update to Carl Sagan's legendary "Cosmos" series, and a deeper dive into some of the topics DeGrasse Tyson addressed in his own series.

Eicher's book will bring you up to date on astronomy and it will also get your imagination going.
By lyndonbrecht
This is an outstanding book, making some rather difficult concepts understandable, and bringing the reader up to date with advances in astronomy and related fields. The photos are good. The writing is clear and it is also clear that Eicher knows his subject and is enthusiastic about it, as you would expect from the editor of a well known astronomy magazine. That said, be aware that the science in this book is still somewhat difficult; it may be a bit of a slow read for some readers, but keep at it, you'll learn a great deal.
Some of the details in the book represent consensus astronomy, understandings shared by many or most astronomers, useful in the present state of knowledge but apt to change quickly with new data. We're in something of a golden age for astronomy and related sciences, despite budget limitations imposed on space agencies such as NASA. Among other things, consensus is that in a billion years the sun will be far larger and hotter and Earth's oceans will boil away, and dark energy is 68.3% of the mass/ energy of the universe. On average a 1-kn asteroid should hit the earth once every 700,000 years and a 140-meter asteroid should hit once every 20,000 years.
Readers interested in the moon will find Chapter 4 of interest. It discusses recent theories of moon formation, including the wonderfully named Great Impact Hypothesis. Chapter 5, "Where has all the water gone" discusses water on Mars and elsewhere in the solar system. It appears that Mars once had liquid water on the surface, and many large valleys suggest erosion by water. So where is it? Water is important because it is intimately tied to life, and also because humans venturing there would find water useful. Chapter 6, "Why did Venus turn inside out" may interest fewer readers, but it discusses the relative lack of impact craters and suggests volcanic activity has remade the surface. Chapter 7, "Is Pluto a planet?" looks at that topic, not that whether it is a "planet" is such a big deal, but it keeps surprising us--new moons discovered in 2010 and 2011. Then there's the Kuiper Belt, which has 1000 small icy bodies but may also have 100,000 objects with diameters of more than 100 km. There's a lot out there.
Chapter 8 looks at planets outside our solar system. The search for exoplanets is vigorous and currently a popular aspect of astronomy, Credible estimates suggest 40 billion planets orbiting within habitable zones of sun-like and red dwarf stars, in the Milky Way, and in the universe could be 100 billion times the 40 billion. That suggests that even if the possibility of life is remote, it probably does exist--that "habitable zone" proviso is the key. Chapter 9 is a little less exciting, on the Milky Way; we're apparently in a barred spiral and our sun orbits the galaxy center at 240 kilometers a second, taking 220 million years for the orbit. Chapter 10 looks at the eventual merger of the Milky Way and the Andromeda galaxy. Chapter 11 discusses the echo of the Big Bang. That one still stumps me, all the matter and all the energy in all the universe contained in a singularity presumably of infinite density and perhaps no larger than the period at then end of this sentence.
Chapter 12 looks at how big the universe is. Tens of billions of light years, but if the universe is infinite the number of light years should also be infinite, another aspect I can't quite wrap my head around--but this chapter helps a bit. There was nothing anywhere, everything nowhere and suddenly there was no more nothing and something became infinite--my phrasing, but again after digesting the chapter I have a little better sense of the possibilities. Chapter 13 examines dark matter. 4.9% of the material in the universe is "normal", that would be us humans and what we usually see as real; 26.8% dark matter and 63.8% dark energy--somehow I envision a vampire astronomer deep in the Carpathians chuckling over dark energy powering things.
The rest of the chapters consider dark energy, black holes, the fate of the universe, and the meaning of life. They sort of all blend in. The eventual fate is an infinite darkness devoid of light save for red dwarf stars, like some foggy stage set for a movie set in dark hours of Victorian London. Eicher's book will get your imagination going.

A Layman's Tour of Earth, the Solar System, Galaxy, and Greater Cosmos
By Tom P
This is an easy read of the current state of astronomy and astronomical observation with lighter touches on cosmology. It contains nice color images and illustrations that ground many of the topics visually and bring them to life. It is an easy read in the sense that it is not mathematical and provides generally interesting discussion of what current observations and understanding imply to the broader topics and questions of time, distance, whether life exists elsewhere, origins and trajectory of the universe, etc. I stumbled on a few typos and convoluted word structure that were surprising given the author's background as Astronomy editor, and also found some chapters to drag a little with longish compilations of observational information. Nonetheless it is a nicely conceived, thoughtful, and in places insightful work that summarizes the findings of the thousands of bright and diligent people - recent and over the centuries- that have brought our knowledge to its current state.
