Cosmos is one of the bestselling science books of all time. In clear-eyed prose, Sagan reveals a jewel-like blue world inhabited by a life form that is just beginning to discover its own identity and to venture into the vast ocean of space.

Bill Bryson has been an enormously popular author both for his travel books and for his books on the English language. Now, this beloved comic genius turns his attention to science. Although he doesn't know anything about the subject (at first), he is eager to learn, and takes information that he gets from the world's leading experts and explains it to us in a way that makes it exciting and relevant.

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.

The number-one best-selling author of The Future of the Mind traverses the frontiers of astrophysics, artificial intelligence, and technology to offer a stunning vision of man's future in space, from settling Mars to traveling to distant galaxies. Formerly the domain of fiction, moving human civilization to the stars is increasingly becoming a scientific possibility - and a necessity. Whether in the near future due to climate change and the depletion of finite resources or in the distant future due to catastrophic cosmological events, humans will one day need to leave Earth.

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 THE SKEPTICS' GUIDE TO THE FUTURE, Steven Novella and his co-authors build upon the work of futurists of the past by examining what they got right, what they got wrong, and how they came to those conclusions. By exploring the pitfalls of each era, they give their own speculations about the distant future, transformed by unbelievable technology ranging from genetic manipulation to artificial intelligence and quantum computing.

In The Vanishing Face of Gaia, British scientist James Lovelock predicts global warming will lead to a Hot Epoch. Lovelock is best known for formulating the controversial Gaia theory in the 1970s, with Ruth Margulis of the University of Massachusetts, which states that organisms interact with and regulate Earth's surface and atmosphere. We ignore this interaction at our peril.

Sixty-six million years ago, an object the size of a city descended from space to crash into Earth, creating a devastating cataclysm that killed off the dinosaurs, along with three-quarters of the other species on the planet. What was its origin? In Dark Matter and the Dinosaurs, Lisa Randall proposes it was a comet that was dislodged from its orbit as the solar system passed through a disk of dark matter embedded in the Milky Way. In a sense it might have been dark matter that killed the dinosaurs.

In Firmament, atmospheric scientist and science communicator Simon Clark offers a rare and accessible tour of the ins and outs of the atmosphere and how we know what we know about it. From the workings of its different layers to why carbon dioxide is special, from pioneers like Pascal to the unsung heroes working in the field to help us understand climate change, Firmament introduces us to an oft-overlooked area of science and not only lays the ground work for us to better understand the debates surrounding the climate today.

The late great astronomer and astrophysicist describes his personal search to understand the nature of the sacred in the vastness of the cosmos. Exhibiting a breadth of intellect nothing short of astounding, Sagan presents his views on a wide range of topics, including the likelihood of intelligent life on other planets, creationism and so-called intelligent design.

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.

A wry and compelling take on the who, how, and why of near-future colonies in space. From bone-whittling microgravity to eye-popping profits, the risks and rewards of space settlement have never been so close at hand.
