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.

Mercury, a lifeless victim of the Sun’s expanding power. Venus, once thought to be lush and fertile, now known to be trapped within a toxic and boiling atmosphere. Mars, the red planet, doomed by the loss of its atmosphere. Jupiter, twice the size of all the other planets combined, but insubstantial. Saturn, a stunning celestial beauty, the jewel of our Solar System. Uranus, the sideways planet and the first ice giant. Neptune, dark, cold and whipped by supersonic winds. Pluto, the dwarf planet, a frozen rock.

Informed by cutting-edge scientific research and sparkling with memorable characters - from the modern druids who worship at Stonehenge each solstice to the Amish farmers who may have the right idea about healthy sleep patterns - Linda Geddes’s Chasing the Sun analyzes all aspects of our relationship to the sun. The fascinating stories, innovative science, and unique perspectives in this book make it clear that the ancients were right to put the sun at the center of our world and that it is crucial that we remember this bond as we shape our lives today.

Since the beginning of human history Mars has been an alluring dream - the stuff of legends, gods, and mystery. The planet most like ours, it has still been thought impossible to reach, let alone explore and inhabit. Now with the advent of a revolutionary new plan, all this has changed. Leading space exploration authority Robert Zubrin has crafted a daring new blueprint, Mars Direct, presented here with engaging anecdotes. The Case for Mars is not a vision for the far future or one that will cost us impossible billions.

We’ve long understood black holes to be the points at which the universe as we know it comes to an end. Often billions of times more massive than the Sun, they lurk in the inner sanctum of almost every galaxy of stars in the universe. Recent research, however, has led to a cascade of new discoveries that have revealed an entirely different side to black holes. As the astrophysicist Caleb Scharf reveals in Gravity’s Engines, these chasms in space-time don’t just vacuum up everything that comes near them; they also spit out huge beams and clouds of matter.

One of the most influential thinkers of our time, Stephen Hawking is an intellectual icon, known not only for the adventurousness of his ideas but for the clarity and wit with which he expresses them. In this new book Hawking takes us to the cutting edge of theoretical physics, where truth is often stranger than fiction, to explain in laymen’s terms the principles that control our universe.

This new and long-awaited sequel to Carl Sagan's international best seller continues the electrifying journey through space and time, linking worlds within and worlds billions of miles away and envisioning a future of science tempered with wisdom. Based on National Geographic's internationally-renowned television series, this groundbreaking and visually stunning book explores how science and civilization grew up together.

It was not easy being a woman of ambition in early 20th-century England, much less one who wished to be a scientist. Cecilia Payne-Gaposchkin overcame prodigious obstacles to become a woman of many firsts: the first to receive a PhD in astronomy from Radcliffe College, the first promoted to full professor at Harvard, the first to head a department there. And, in what has been called "the most brilliant PhD thesis ever written in astronomy", she was the first to describe what stars are made of.

Science fiction allows us to go places we can only dream of seeing - other worlds, distant stars, entirely different galaxies. While not every story is concerned with the hard science behind space travel and other futuristic ventures, fiction can give us amazing insight into what we could be capable of and what we dream of doing. In these 10 lectures, Professor Erin Macdonald interweaves real science and the achievements of the imagination to reveal the truth that underlies our favorite stories and sheds light on what the future may hold.

For at least 20,000 years, we have led not just an earthly existence, but a cosmic one. Celestial cycles drove every aspect of our daily lives. Our innate relationship with the stars shaped who we are - our art, religious beliefs, social status, scientific advances, and even our biology. But over the last few centuries we have separated ourselves from the universe that surrounds us. It's a disconnect with a dire cost.

By the star physicist and author of multiple #1 Sunday Times bestsellers, a major and definitive narrative work on black holes and how they can help us understand the universe.

Where is the best place to find life beyond Earth? We often look to Mars as the most promising site in our solar system, but recent scientific missions have revealed that some of the most habitable real estate may actually lie farther away. Beneath the frozen crusts of several of the small, ice-covered moons of Jupiter and Saturn lurk vast oceans that may have been in existence for as long as Earth, and together may contain more than 50 times its total volume of liquid water. Could there be organisms living in their depths?

Spaceflight is notoriously dangerous. Beyond launch mishaps and equipment failures, astronauts face serious health problems from long-term weightlessness and high-energy radiation. Not to mention, the space environment is a near-perfect vacuum that can quickly kill anyone who is unprotected. Drawing on the hard-won insights of NASA astronauts and space researchers, this 12-lecture course presents the perils of spaceflight and what experts have done to make them survivable. It also deals with livability in space, including nutrition, sleep, environmental control, and personal hygiene.

As technological advances and the creation of flying aircraft became realities, the sighting of UFOs increased, as did the interest in potential contact with aliens. It would hardly be groundbreaking for scientists in the 20th century to have a lunchtime discussion in which the search for extraterrestrial life arises, and the question of where it might reside is innocuous enough. However, a furor was created somewhat innocently when physicist Enrico Fermi voiced his “casual lunchtime remark” in the presence of colleagues in 1950.

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.

A talk by Terence McKenna about how our global culture is preparing to depart for the stars, so we must begin to pack for the trip. He begins with a discussion of botanical dimensions of folk medicine which are lost in pharmacology and how this is being uncovered by the New Age archaic revival. McKenna envisions an end to the current age, which has consisted of eons of boredom. He goes on to discuss the growing wonder of the universe as presented by leading astronomers Stephen Hawking and Carl Sagan.

With all the passion, curiosity, and precise yet lyrical prose that have marked his previous books, Alan Lightman here explores the emotional and philosophical questions raised by discoveries in science, focusing most intently on the human condition and the needs of humankind. He looks at the difficult dialogue between science and religion, the conflict between our human desire for permanence and the impermanence of nature, the possibility that our universe is simply an accident, the manner in which modern technology has separated us from direct experience of the world, and our resistance to the view that our bodies and minds can be explained by scientific logic and laws.

Speaking with key leaders of the latest space programs and innovations, Rod Pyle shares the excitement and promise of this new era of exploration and economic development. From NASA and the Russian space agency Roscosmos, to emerging leaders in the private sector, Space 2.0 examines the new partnerships that are revolutionizing spaceflight and changing the way we reach for the stars.

Have you ever wondered if there are seasons on the moon or if space tourism will ever become commonplace? So has Dr. Maggie Aderin-Pocock. In fact, she earned her nickname “Lunatic” because of her deep fascination for all things lunar. In her lucidly written, comprehensive guide to the moon, Aderin-Pocock takes listeners on a journey to our closest celestial neighbor, exploring folklore, facts, and future plans.

Described as the "ultimate engineer" during his career at NASA, George M. Low was a visionary architect and leader from the agency's inception in 1958 to his retirement in 1976. As chief of manned spaceflight at NASA, Low was instrumental in the Mercury, Gemini, and Apollo programs. Low's pioneering work paved the way for President Kennedy's decision to make a lunar landing NASA's primary goal in the 1960s.
