Astronomers have been studying the heavens for thousands of years, but until recently much of the cosmos has been invisible to the human eye. Launched in 2003, the Spitzer Space Telescope has brought the infrared universe into focus as never before. Michael Werner and Peter Eisenhardt are among the scientists who worked for decades to bring this historic mission to life. Here is their inside story of how Spitzer continues to carry out cutting-edge infrared astronomy to help answer fundamental questions that have intrigued humankind since time immemorial: Where did we come from? How did the universe evolve? Are we alone?
In this panoramic book, Werner and Eisenhardt take readers on a breathtaking guided tour of the cosmos in the infrared, beginning in our solar system and venturing ever outward toward the distant origins of the expanding universe. They explain how astronomers use the infrared to observe celestial bodies that are too cold or too far away for their light to be seen by the eye, to conduct deep surveys of galaxies as they appeared at the dawn of time, and to peer through dense cosmic clouds that obscure major events in the life cycles of planets, stars, and galaxies.
Featuring many of Spitzer’s spectacular images, More Things in the Heavens provides a thrilling look at how infrared astronomy is aiding the search for exoplanets and extraterrestrial life, and transforming our understanding of the history and evolution of our universe.
Even after the last century, which saw important and startling discoveries about our own planet, our solar system and the stars and galaxies beyond, there remain more questions than answers. But those questions - What is dark matter? Are we alone in the universe? Is time travel possible? - provide a fascinating insight into the vastness and infinite possibilities of space that we're yet to determine.
The sheer scale of the universe can be intimidating, but in this easily digestible book we embark on an incredible journey through all the essential astronomical discoveries, from the beliefs of ancient civilizations, through to the recent groundbreaking observations of the gravitational waves predicted by Einstein over 100 years ago. There's never been a better time to get to grips with the universe and this essential guide to the cosmos is the perfect place to start!
The map contains anomalies that challenge our understanding of the universe. It will force us to revisit what is known and what is unknown, to construct a new model of our universe. This is the first book to address what will be an epoch-defining scientific paradigm shift. Stuart Clark will ask if Newton's famous laws of gravity need to be rewritten; if dark matter and dark energy are just celestial phantoms? Can we ever know what happened before the Big Bang? What’s at the bottom of a black hole? Are there universes beyond our own? Does time exist? Are the once immutable laws of physics changing?

Fun activities embrace modern technology with the best apps and websites that make it easy for anyone to observe the greatest spectacles of the sky without a telescope or other expensive equipment.
An expert in his field, Bob King teaches night sky courses and makes cosmic mysteries practical and accessible for skywatchers new and old. Understand what makes stars twinkle and where meteors come from in this complete guide to the heavens. Unique illustrations and stunning photos help the reader understand the concepts presented. Tips on how to photograph satellites, eclipses and the aurora are also included. Unravel the secrets of the universe while deepening your appreciation of its beauty through this clear and concise guide.
Here we visit observatories and universities where leading scientists describe how they envision the very early stages, the history, and the future of the universe. The discussions help us to make sense of many recent findings, including cosmic ripples, which supply evidence of the first billionth of a second of the universe; anomalous galactic structures such as the Great Wall, the Great Void, and the Great Attractor; and the mysterious presence of dark matter, massive but invisible. Lemonick assembles this information into a comprehensive, up-to-date picture of modern cosmology, and a portrait of its often contentious practitioners.

These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
This book is intended to help you live your life, and to shed some light on your own values and ethics, if you don’t believe in God. More than just a primer on Humanism, but not quite a full-blown treatise on philosophy, it offers some answers to those crucial questions Socrates asked: What is true? And how shall we live our lives? Those of us who don’t believe in the supernatural sometimes struggle to understand how we can ground ourselves ethically, and how to find truth, meaning, purpose and joy. This book offers ideas about how to know, without depending on Holy Scriptures or guidance from a deity, what it means to lead a good and ethical life.
“Humanism is a value system whose time has come: a positive philosophy for the surging proportion of the world’s population who indicate ‘None’ as their religion but seek meaning, morality, and purpose in their lives. Michael Werner’s statement of Humanism is clear, effective, and graceful, just right for our times.” Steven Pinker, professor of psychology, Harvard University author, “The Better Angels of Our Nature” and “How the Mind Works.”
“Mike Werner captures the depth and breadth of Humanism in his latest work. He shows us what love, reason, imagination and science can have in common. In doing so, he demonstrates what we all have to live for, strive for, and believe in.” Roy Speckhardt, executive director, American Humanist Association
“Outstanding and a must read for everyone who takes life seriously.” Rev. William R. Murry, former president, Meadville Lombard Theological School, University of Chicago
What is the nature of space and time? How do we fit within the universe? How does the universe fit within us? There’s no better guide through these mind-expanding questions than acclaimed astrophysicist and best-selling author Neil deGrasse Tyson.
But today, few of us have time to contemplate the cosmos. So Tyson brings the universe down to Earth succinctly and clearly, with sparkling wit, in tasty chapters consumable anytime and anywhere in your busy day.
While you wait for your morning coffee to brew, for the bus, the train, or a plane to arrive, Astrophysics for People in a Hurry will reveal just what you need to be fluent and ready for the next cosmic headlines: from the Big Bang to black holes, from quarks to quantum mechanics, and from the search for planets to the search for life in the universe.
