Light of the Stars is science at the grandest of scales, and it tells a radically new story about what we are: one world in a universe awash in planets. Building on his widely discussed scientific papers and New York Times op-eds, astrophysicist Adam Frank shows that not only is it likely that alien civilizations have existed many times before, but also that many of them have driven their own worlds into dangerous eras of change.

With a foreword from Professor Brian Cox and access to all the latest NASA mission information, Andrew Cohen takes listeners on a voyage of discovery via the probes and telescopes exploring the outer reaches of our galaxy, revealing how it was formed and how it will inevitably be destroyed by the enigmatic black hole at its heart. And beyond our galaxy, the expanding universe, which holds clues to the biggest mystery of all - how did it all begin?

Gene Kranz was present at the creation of America's manned space program and was a key player in it for three decades. As a flight director in NASA's Mission Control, Kranz witnessed firsthand the making of history. He participated in the space program from the early days of the Mercury program to the last Apollo mission, and beyond. He endured the disastrous first years when rockets blew up and the United States seemed to fall further behind the Soviet Union in the space race.

Most historians study the smallest slivers of time, emphasizing specific dates, individuals, and documents. But what would it look like to study the whole of history, from the big bang through the present day - and even into the remote future? How would looking at the full span of time change the way we perceive the universe, the earth, and our very existence? These were the questions David Christian set out to answer when he created the field of "Big History", the most exciting new approach to understanding where we have been, where we are, and where we are going.

Gravity controls everything from the falling of an apple to the rising of ocean’s tides to the motions of the heavens above. If you’ve ever wondered how this most puzzling force works across our entire universe, you will be delighted by this 24-part course that is accessible to any curious person, regardless of your science education. No other product on the market presents the subject of gravity in as much detail as this course, which will follow the past 400 years of research and experimentation in the field.

This course chronicles the history of Earth and life on Earth from the point of view of the minerals that made it all happen. A major theme is how minerals and life coevolved, leading to the unprecedented mineral diversity on our world compared to the other planets in the solar system. Professor Hazen tells this epic story in 48 action-packed lectures that take you from the big bang to the formation of the solar system to the major milestones that marked the evolution of Earth and life.

Time moves forward, not backward---everyone knows you can't unscramble an egg. In the hands of one of today's hottest young physicists, that simple fact of breakfast becomes a doorway to understanding the Big Bang, the universe, and other universes, too. In From Eternity to Here, Sean Carroll argues that the arrow of time, pointing resolutely from the past to the future, owes its existence to conditions before the Big Bang itself---a period of modern cosmology of which Einstein never dreamed.

Welcome to the Universe is a personal guided tour of the cosmos by three of today's leading astrophysicists. Inspired by the enormously popular introductory astronomy course that Neil deGrasse Tyson, Michael A. Strauss, and J. Richard Gott taught together at Princeton, this book covers it all - from planets, stars, and galaxies to black holes, wormholes, and time travel.

In lyric, accessible prose, Carlo Rovelli invites us to consider questions about the nature of time that continue to puzzle physicists and philosophers alike. For most listeners, this is unfamiliar terrain. We all experience time, but the more scientists learn about it, the more mysterious it appears. We think of it as uniform and universal, moving steadily from past to future, measured by clocks. Rovelli tears down these assumptions one by one, revealing a strange universe where, at the most fundamental level, time disappears.

"It doesn't take an Einstein to understand modern physics," says Professor Wolfson at the outset of these 24 lectures on what may be the most important subjects in the universe: relativity and quantum physics. Both have reputations for complexity. But the basic ideas behind them are, in fact, simple and comprehensible by anyone. These dynamic and illuminating lectures begin with a brief overview of theories of physical reality starting with Aristotle and culminating in Newtonian or "classical" physics.

Professor Brian Cox uncovers some of the most extraordinary natural events on Earth and in the universe and beyond. From the immensity of the universe and the roundness of Earth to the form of every single snowflake, the forces of nature shape everything we see. Pushed to extremes, the results are astonishing. In seeking to understand the everyday world, the colours, structure, behaviour and history of our home, we develop the knowledge and techniques necessary to step beyond the everyday.

Max Tegmark leads us on an astonishing journey through past, present and future, and through the physics, astronomy, and mathematics that are the foundation of his work, most particularly his hypothesis that our physical reality is a mathematical structure and his theory of the ultimate multiverse. In a dazzling combination of both popular and groundbreaking science, he not only helps us grasp his often mind-boggling theories, but he also shares with us some of the often surprising triumphs and disappointments that have shaped his life as a scientist.

Authors Christopher Knight and Alan Butler realized that the ancient system of geometry they presented in their earlier breakthrough study works as perfectly for the Moon as it does the Earth. On further investigation, they found a consistent sequence of beautiful integer numbers when looking at every major aspect of the Moon - no such pattern emerges for any other planet or moon in the solar system. In addition, Knight and Butler discovered that the Moon possesses few or no heavy metals and has no core - something that should not be possible.

Stephen Hawking not only unraveled some of the universe's greatest mysteries but also believed science plays a critical role in fixing problems here on Earth. Now, as we face immense challenges on our planet - including climate change, the threat of nuclear war, and the development of artificial intelligence - he turns his attention to the most urgent issues facing us. Will humanity survive? Should we colonize space? Does God exist? These are just a few of the questions Hawking addresses in this wide-ranging, passionately argued final book from one of the greatest minds in history.

In Cosmos, the late astronomer Carl Sagan cast his gaze over the magnificent mystery of the Universe and made it accessible to millions of people around the world. Now in this stunning sequel, Carl Sagan completes his revolutionary journey through space and time.

Apollo is the behind-the-scenes story of an epic achievement. Based on exhaustive research that included many exclusive interviews, Apollo tells how America went from a standing start to a landing on the moon at a speed that now seems impossible. It describes the unprecedented engineering challenges that had to be overcome to create the mammoth Saturn V and the facilities to launch it. It takes you into the tragedy of the fire on Apollo 1, the first descent to the lunar surface, and the rescue of Apollo 13.

Space and time form the very fabric of the cosmos. Yet they remain among the most mysterious of concepts. Is space an entity? Why does time have a direction? Could the universe exist without space and time? Can we travel to the past?

Perhaps the biggest question Stephen Hawking tried to answer in his extraordinary life was how the universe could have created conditions so perfectly hospitable to life. In order to solve this mystery, Hawking studied the big bang origin of the universe, but his early work ran into a crisis when the math predicted many big bangs producing a multiverse—countless different universes, most of which would be far too bizarre to ​harbor life.

In The Universe, today's most influential science writers explain the science behind our evolving understanding of The Universe and everything in it, including the cutting-edge research and discoveries that are shaping our knowledge. Lee Smolin reveals how math and cosmology are helping us create a theory of the whole universe. Neil Turok analyzes the fundamental laws of nature, what came before the big bang, and the possibility of a unified theory. And much more.

There was a time when “universe” meant all there is. Everything. Yet, in recent years discoveries in physics and cosmology have led a number of scientists to conclude that our universe may be one among many. With crystal-clear prose and inspired use of analogy, Brian Greene shows how a range of different “multiverse” proposals emerges from theories developed to explain the most refined observations of both subatomic particles and the dark depths of space.
