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.

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.

Born and raised in remote Broken Hill, Trevor Barry left school after year ten to work in the mines. Years later, a single glimpse of Saturn through a colleague's telescope knocked Trevor's world completely off its axis, turning his whole life upside down. With his newfound passion and armed with decades of outback know-how, Trevor set about building an observatory in his backyard using bits and pieces from his shed, a second-hand washing machine motor, rainwater tank parts and an old catamaran wire.

"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.

Every year, 200 experts across machine learning, automation, robotics, and space arrive in Palm Springs for MARS to share new ideas about how these four fields will shape our future. TV host and maker of things Adam Savage (MythBusters) takes listeners deep inside the MARS conference. In interviews with more than a dozen leading scientists and thinkers, Savage explores the mind-blowing and often misunderstood ways in which science and innovation are transforming the way we live, work, and play.

So you’ve fallen in love with space and now you want to see it for yourself, huh? You want to witness the birth of a star, or visit the black hole at the center of our galaxy? You want to know if there are aliens out there, or how to travel through a wormhole? You want the wonders of the universe revealed before your very eyes? Well stop, because all that will probably kill you.

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?

How big is the Solar System? What actually orbits our Sun? Why should I even be interested in space? we'll answer these and a whole host of other questions. We will have a series dedicated to each of our planets and showcase beautiful images and videos captured by probes and spacecraft of our amazing Solar System.

The fate of the Lost Ark of the Covenant is one of the great historical mysteries of all time. The Bible contains hundreds of references to the Ark's power, but the Ark itself mysteriously disappears from recorded history sometime after the building of the Temple of Solomon. After 10 years of searching through the dusty archives of Europe and the Middle East, Graham Hancock has succeeded where scores of others have failed. This intrepid journalist has tracked down the true story behind the myths and legends - revealing where the Ark is today, how it got there, and why it remains hidden.

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.

From the discovery of entirely new kinds of galaxies to a window into cosmic ‘prehistory’, Bothwell shows us the universe as we’ve never seen it before - literally. Since the dawn of our species, people all over the world have gazed in awe at the night sky. But for all the beauty and wonder of the stars, when we look with just our eyes we are seeing and appreciating only a tiny fraction of the universe. What does the cosmos have in store for us beyond the phenomena we can see, from black holes to supernovas?

There are deep connections between stars and atoms, between the cosmos and the microworld. Just six numbers, imprinted in the "Big Bang", determine the essential features of our entire physical world. Moreover, cosmic evolution is astonishingly sensitive to the values of these numbers. If any one of them were "untuned", there could be no stars and no life. This realization offers a radically new perspective on our universe, our place in it, and the nature of physical laws.

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.

How can we make intelligent decisions about our increasingly technology-driven lives if we don’t understand the difference between the myths of pseudoscience and the testable hypotheses of science? Pulitzer Prize-winning author and distinguished astronomer Carl Sagan argues that scientific thinking is critical not only to the pursuit of truth but to the very well-being of our democratic institutions.

Astronomer Florian Freistetter has chosen 100 stars that have almost nothing in common. Some are bright and famous, some shine so feebly you need a huge telescope. There are big stars, small stars, nearby stars and faraway stars. Some died a while ago, others have not even yet come into being. Collectively they tell the story of the whole world, according to Freistetter. There is Algol, for example, the Demon Star, whose strange behaviour has long caused people sleepless nights.

In a time when our political and cultural perspectives feel more divisive than ever, Tyson provides a much-needed antidote to so much of what divides us, while making a passionate case for the twin engines of enlightenment—a cosmic perspective and the rationality of science. After thinking deeply about how a scientist views the world and about what Earth looks like from space, Tyson has found that terrestrial thoughts change as our brain resets and recalibrates life's priorities, along with the actions we might take in response.

On a cold January morning in 1986, NASA launched the Space Shuttle Challenger, despite warnings against doing so by many individuals including Allan McDonald. The fiery destruction of Challenger on live television moments after launch remains an indelible image in the nation's collective memory. In Truth, Lies, and O-Rings, McDonald, a skilled engineer and executive, relives the tragedy from where he stood at Launch Control Center.

Already internationally acclaimed for his elegant, lucid writing on the most challenging notions in modern physics, Sean Carroll is emerging as one of the greatest humanist thinkers of his generation as he brings his extraordinary intellect to bear not only on the Higgs boson and extra dimensions but now also on our deepest personal questions. Where are we? Who are we? Are our emotions, our beliefs, and our hopes and dreams ultimately meaningless out there in the void?

Author of the New York Times best seller The Beginning of Infinity, David Deutsch, explores the four most fundamental strands of human knowledge: quantum physics, and the theories of knowledge, computation, and evolution - and their unexpected connections. Taken together, these four strands reveal a deeply integrated, rational, and optimistic worldview. It describes a unified fabric of reality that is objective and comprehensible, in which human action and thought are central.
