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?

Author Jim Holt explores the greatest metaphysical mystery of all: why is there something rather than nothing? This runaway best seller, which has captured the imagination of critics and the public alike, traces our latest efforts to grasp the origins of the universe. Holt adopts the role of cosmological detective, traveling the globe to interview a host of celebrated scientists, philosophers, and writers.

The author presents evidence from highly credible sources that you are an eternal spiritual being that is temporarily residing in what might be regarded as a kind of spacesuit—aka a human body—that allows you to operate in physical reality. He suggests that you will likely exist forever, albeit in other realities that are quite different from this one. He urges you to read this book, weigh the evidence, and then ask yourself, “Does knowing I will exist forever change how I think about life?” He also suggests that you give some thought to what you might do to make the most of the ...

The final book from Professor Stephen Hawking, the best-selling author of A Brief History of Time and arguably the most famous scientist of our age, Brief Answers to the Big Questions is a profound, accessible and timely reflection on the biggest questions in science. Professor Hawking was a brilliant theoretical physicist, an influential author and thinker and a great popular communicator.

UNCOVER THE SPACE MISSION THAT “NEVER HAPPENED” Buried ruins. Alien artifacts. A silent launch no one was supposed to see. In 1972, as the world believed the Apollo program was drawing to a close, a myth began to stir—one so compelling that it refused to vanish. Decades later, a grainy video would appear online, claiming to show the lost footage of a secret joint U.S.–Soviet moon mission: Apollo 20. This supposed mission discovered alien ruins beneath the lunar ice, a colossal abandoned spacecraft, and even a strange, preserved humanoid dubbed the “Lunar Mona Lisa.” The footage ...

Are there other dimensions beyond our own? Is time travel possible? Can we change the past? Are there gateways to parallel universes? All of us have pondered such questions, but there was a time when scientists dismissed these notions as outlandish speculations. Not any more. Today, they are the focus of the most intense scientific activity in recent memory. In Hyperspace, Michio Kaku offers the first book-length tour of the most exciting (and perhaps most bizarre) work in modern physics.

In Calculating the Cosmos, Ian Stewart presents an exhilarating guide to the cosmos, from our solar system to the entire universe. He describes the architecture of space and time, dark matter and dark energy, how galaxies form, why stars implode, how everything began, and how it's all going to end. He considers parallel universes, the fine-tuning of the cosmos for life, what forms extraterrestrial life might take, and the likelihood of life on Earth being snuffed out by an asteroid.

In this grand poetic vision of the universe, Lawrence Krauss tells the dramatic story of the discovery of the hidden world that underlies reality - and our place within it. Reality is not what you think or sense - it’s weird, wild, and counterintuitive, and its inner workings seem at least as implausible as the idea that something can come from nothing. With his trademark wit and accessible style, Krauss leads us to realms so small that they are invisible to microscopes, to the birth and rebirth of light, and into the natural forces that govern our existence.

Is Earth merely an insignificant speck in a vast and meaningless universe? On the contrary: The Privileged Planet shows that this cherished assumption of materialism is dead wrong. In this provocative book, Guillermo Gonzalez and Jay W. Richards present a staggering array of evidence that exposes the hollowness of this modern dogma.

Icy, rocky, sometimes dusty, always mysterious – comets and asteroids are among the Solar System's very oldest inhabitants, formed within a swirling cloud of gas and dust in the area of space that eventually hosted the Sun and its planets. Locked within each of these extra-terrestrial objects is the 4.6-billion-year wisdom of Solar System events, and by studying them at close quarters using spacecraft we can coerce them into revealing their closely-guarded secrets. This offers us the chance to answer some fundamental questions about our planet and its inhabitants.

In this audiobook, astrophysicist Janna Levin blends memoir and visionary science to provide a groundbreaking personal account of her life and ideas.

Space is a place of unparalleled possibility for humanity, and it's undergoing a revolution. A wave of companies led by gutsy entrepreneurs are unlocking opportunities that fire the imagination. No, it's not hotels on Mars or day trips to orbit (yet), but it's an awe-inspiring transformation driven by innovative technologies, creative approaches, hard work, and—for the first time—market forces.

In this astonishing rediscovery of the final Apollo moon landings, the acclaimed author of Chesapeake Requiem reveals that these extraordinary yet overshadowed missions - distinguished by the use of the revolutionary lunar roving vehicle - deserve to be celebrated as the pinnacle of human adventure and exploration.

Climate change has been a perplexing problem for years. Casey's research into the Sun's activity, which began almost a decade ago, resulted in discovery of a solar cycle that is now reversing from its global warming phase to that of dangerous global cooling for the next 30 years or more. This new cold climate will dramatically impact the world's citizens.

More than half a century after humans first walked on the Moon, exciting new space adventures are in the works. Thanks to major advances in rocketry, robotics, and other space technologies, humanity is on the verge of returning to the Moon, exploring Mars, building permanent orbiting space stations, expanding space tourism, and pushing the boundaries of exploration throughout the solar system and beyond. The Future of Space Exploration explores these exciting developments in 12 half-hour episodes, hosted by aerospace engineer and executive Dr. Ariel Ekblaw.

The modern materialist approach to life has conspicuously failed to explain such central mind-related features of our world as consciousness, intentionality, meaning, and value. This failure to account for something so integral to nature as mind, argues philosopher Thomas Nagel, is a major problem, threatening to unravel the entire naturalistic world picture, extending to biology, evolutionary theory, and cosmology. Since minds are features of biological systems that have developed through evolution, the standard materialist version of evolutionary biology is fundamentally incomplete.

This playful, entertaining, and mind-bending introduction to modern physics briskly explains Einstein's general relativity, quantum mechanics, elementary particles, gravity, black holes, the complex architecture of the Universe, and the role humans play in this weird and wonderful world. Carlo Rovelli, a renowned theoretical physicist, is a delightfully poetic and philosophical scientific guide. He takes us to the frontiers of our knowledge: To the most minute reaches of the fabric of space, back to the origins of the cosmos, and into the workings of our minds.

We are living in a golden age in astronomy and in the search for life the universe. Over the last few decades, space exploration has shown that not only are there habitable environments within our solar system, but there are millions of exoplanets within our galaxy that could support life. We are on the cusp of breakthroughs that will revolutionize our understanding of our place in the cosmos in. In The Secret Life of the Universe, astrobiologist and the director of the Carl Sagan Center at the SETI Institute Nathalie A. Cabrol takes us to the frontiers of the search for life.

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.
