Are you puzzled by pulsars? Baffled by black holes? Bewildered by the big bang? If so, here are succinct, crystal-clear answers to more than 100 of the most significant questions about the essential nature of the universe - questions that have fired the imagination since the beginning of history. Over the course of this fantastic voyage, the origins, the discoveries, and the stunning achievements of astronomy will unfold before your eyes

It is now known that we live in a galaxy with more planets than stars. The Milky Way alone encompasses 30 trillion potential home planets. Scientists Trefil and Summers bring listeners on a marvelous experimental voyage through the possibilities of life-unlike anything we have experienced so far - that could exist on planets outside our own solar system.

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.

Right now, you are orbiting a black hole. The Earth goes around the Sun, and the Sun goes around the centre of the Milky Way: a supermassive black hole—the strangest and most misunderstood phenomenon in the galaxy. In A Brief History of Black Holes, University of Oxford astrophysicist Dr Becky Smethurst charts the scientific breakthroughs that have uncovered the weird and wonderful world of black holes, from Hawking radiation to the iconic first photographs of a black hole in 2019.

Written in simple and accessible language, this nontechnical introduction to cosmology, or the creation and development of the universe, explains the discipline, covers its history, details the latest developments, and explains what is known, what is believed, and what is purely speculative. In addition, the author discusses the development of the Big Bang theory, and more speculative modern issues like quantum cosmology, superstrings, and dark matter.

Astrobiology is an exciting new subject, and one, arguably, more interdisciplinary than any other. Astrobiologists seek to understand the origin and evolution of life on Earth in order to illuminate and guide the search for life on other planets. In this Very Short Introduction, David C. Catling introduces the subject through our understanding of the factors that allowed life to arise and persist on our own planet, and for the signs we are looking for in the search for extraterrestrial life.

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?

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.

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.

The product of research around the globe and interviews with dozens of prominent scientists, God's Equation tells us it is almost as though Einstein were God's mouthpiece, revealing the most fundamental truths about our larger environment, truths scientists are just now confirming.

How does it feel to orbit the Earth 10 times faster than a speeding bullet? What's it like to eat, sleep and go to the toilet in space? And where to next - the moon, Mars or beyond? Ask an Astronaut is Tim's personal guide to life in space, based on his historic Principia mission and the thousands of questions he has been asked since his return to Earth.

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.

All the matter and light we can see in the universe makes up a trivial five per cent of everything. The rest is hidden. This could be the biggest puzzle that science has ever faced. Since the 1970s, astronomers have been aware that galaxies have far too little matter in them to account for the way they spin around: they should fly apart, but something concealed holds them together. That ’something' is dark matter - invisible material in five times the quantity of the familiar stuff of stars and planets.

Sara Seager has always been in love with the stars: so many lights in the sky, so much possibility. Now a pioneering planetary scientist, she searches for exoplanets - especially that distant, elusive world that sustains life. But with the unexpected death of Seager’s husband, the purpose of her own life becomes hard for her to see. Suddenly, at 40, she is a widow and the single mother of two young boys. For the first time, she feels alone in the universe.

The Science of Star Trek explores one of the greatest science-fiction universes ever created and showcases the visionary tech that inspired and influenced the real-world science of today. The perfect Star Trek gift for fans of the franchise, this book addresses many unanswered, burning questions, including: What can Star Trek tell us about aliens in our Milky Way?; How has Star Trek influenced space culture?; What can Star Trek tell us about planet hunting?; What Star Trek machines came true?; And when will we boldly go?

For as long as humans have lived, we have lived beneath the stars. But under the glow of today’s artificial lighting, we have lost the intimacy our ancestors once shared with the cosmos. In Starborn, cosmologist Roberto Trotta reveals how stargazing has shaped the course of human civilization. The stars have served as our timekeepers, our navigators, our muses—they were once even our gods. How radically different would we be, Trotta also asks, if our ancestors had looked up to the night sky and seen… nothing?

Now in its fourth edition, this low-cost astronomy audio-textbook is designed for a one-semester introductory astronomy course aimed at non-science majors and future teachers. This new edition brings the latest astronomical discoveries together with cutting-edge teaching and learning strategies designed specifically to improve student learning and retention.

Not long ago, the Solar System was the only example of a planetary system - a star and the bodies orbiting it - that we knew. Now, we know thousands of planetary systems, and have even been able to observe planetary systems at the moment of their birth.

Join Ryan T. Kirby, an experienced astronomer, and educator, in an exploration that will take you to the stars! In this short book, Ryan aims at teaching you everything you need to know about astronomy and stargazing from scratch!
