Galileo’s Dialogue Concerning the Two Chief World Systems compares the Copernican or Heliocentric system with the Ptolemaic or Peripatetic, system of the cosmos. Published in Florence in 1632, it resulted in him being tried before the Inquisition. Using the dialogue form, Galileo masterfully shows the truth of the Copernican system that the Earth revolves around the Sun. The Dialogue is one of the most important treatises ever written. A work of supreme clarity and accessibility, it remains as accessible now as when it was published.

Knowledge of the basic ideas and principles of science is fundamental to cultural literacy. But most books on science are often too obscure or too specialized to do the general listener much good.

Stephen Hawking’s worldwide best seller A Brief History of Time remains a landmark volume in scientific writing. But for those who have asked for a more accessible formulation of its key concepts - the nature of space and time, the role of God in creation, and the history and future of the universe - A Briefer History of Time is Professor Hawking’s response.

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.

A Crack in Everything is the story of how black holes came in from the cold and took cosmic centre stage. As a journalist, Marcus Chown interviews many of the scientists who made the key discoveries, and, as a former physicist, he translates the most esoteric of science into everyday language. The result is a uniquely engaging audiobook that tells one of the great untold stories in modern science.

Janna Levin takes us on an evocative exploration of black holes, provoking us to imagine the visceral experience of a black hole encounter. She reveals the influence of black holes as they populate the universe, sculpt galaxies, and even infuse the whole expanse of reality that we inhabit. Lively, engaging, and utterly unique, Black Hole Survival Guide is not just informative - it is, as well, a wonderful listen from first to last.

The story of the men and women who drove the Voyager spacecraft mission, told by a scientist who was there from the beginning. The Voyager spacecraft are our farthest-flung emissaries--11.3 billion miles away from the crew who built and still operate them decades after their launch.

Mapping the Heavens provides a tour of the "greatest hits" of cosmological discoveries - the ideas that reshaped our universe over the past century. The cosmos, once understood as a stagnant place filled with the ordinary, is now a universe that is expanding at an accelerating pace, propelled by dark energy and structured by dark matter. Priyamvada Natarajan, our guide to these ideas, is at the forefront of the research - an astrophysicist who literally creates maps of invisible matter in the universe.

Most of us have heard of black holes and supernovas, galaxies and the big bang. But few of us understand more than the bare facts about the universe we call home. What is really out there? How did it all begin? Jo Dunkley begins in Earth's neighborhood, explaining the nature of the solar system, the stars in our night sky, and the Milky Way. She then moves out past nearby galaxies - and back in time - to the horizon of the observable universe, which contains over a hundred billion galaxies, each with billions of stars, many orbited by planets, some of which may host life.

A noted space expert explains the current revolution in spaceflight, where it leads, and why we need it. Astronautical engineer Robert Zubrin spells out the potential of these new developments in an engrossing narrative that is visionary yet grounded by a deep understanding of the practical challenges. Fueled by the combined expertise of the old aerospace industry and the talents of Silicon Valley entrepreneurs, spaceflight is becoming cheaper.

Space is a world devoid of the things we need to live and thrive: air, gravity, hot showers, fresh produce, privacy, beer. Space exploration is in some ways an exploration of what it means to be human. How much can a person give up? How much weirdness can they take? What happens to you when you can’t walk for a year? Have sex? Smell flowers? What happens if you vomit in your helmet during a space walk? Is it possible for the human body to survive a bailout at 17,000 miles per hour?

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?

The ID The Future (IDTF) podcast carries on Discovery Institute's mission of exploring the issues central to evolution and intelligent design. IDTF is a short podcast providing you with the most current news and views on evolution and ID. IDTF delivers brief interviews with key scientists and scholars developing the theory of ID, as well as insightful commentary from Discovery Institute senior fellows and staff on the scientific, educational and legal aspects of the debate. Episode notes and archives available at idthefuture.com.

In Three Roads to Quantum Gravity, Lee Smolin provides an accessible overview of the attempts to build a final "theory of everything." He explains in simple terms what scientists are talking about when they say the world is made from exotic entities such as loops, strings, and black holes and tells the fascinating stories behind these discoveries: the rivalries, epiphanies, and intrigues he witnessed firsthand.

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.

This course guides listeners through the sights of the naked- eye sky, wherein we directly witness the effects of the turning and revolving of the Earth, the artistry painted by the human mind using the sky and stars, and how the view changes with time and with our place on the planet.

In August 2006, the International Astronomical Union voted Pluto out of planethood. Far from the sun, tiny, and eccentric in orbit, it's a wonder Pluto has any fans. Yet during the mounting debate over Pluto's status, Americans rallied behind the extraterrestrial underdog.

Consider these commonly held scientific beliefs: Planetary orbits are fixed ellipses; we only use 10 percent of our brains; nothing travels faster than light; a thrown object’s trajectory is a parabola. They seem correct, but they’re all misconceptions that aren’t entirely accurate. There’s much more to the story than you think. These magnificent 24 lectures are devoted to busting myths, clearing up confusion, and giving you scientific epiphanies that could change how you think about your everyday world.

On July 14, 2015, something amazing happened. More than three billion miles from Earth, a small NASA spacecraft called New Horizons screamed past Pluto at more than 32,000 miles per hour, focusing its instruments on the long-mysterious icy worlds of the Pluto system, and then, just as quickly, continued on its journey out into the beyond.
