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.

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.

Comet begins with a breathtaking journey through space astride a comet. Pulitzer Prize-winning astronomer Carl Sagan, author of Cosmos and Contact, and writer Ann Druyan explore the origin, nature, and future of comets, and the exotic myths and portents attached to them. The authors show how comets have spurred some of the great discoveries in the history of science and raise intriguing questions about these brilliant visitors from the interstellar dark.

Were the fates of the dinosaurs and the origins of humans tied to the wanderings of a comet?

How big is our galaxy? Is there life on those distant planets? Are we really made of star dust? And where do stars even come from? In An Earthling's Guide to Outer Space, we finally have the answers to all those questions and more. With clarity, wisdom, and a great deal of enthusiasm, McDonald explores the curiosities of the big blue planet we call home as well as our galactic neighbors - from Martian caves to storm clouds on Jupiter to the nebulae at the far end of the universe.

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.

For millennia, the moon has been associated with many central concerns of human existence: love, passion, fertility, mystery, death and rebirth, and the divine feminine. For Wiccans and other Pagan practitioners, the moon is a vital presence with much to teach us. Wicca Moon Magic by best-selling author Lisa Chamberlain is for anyone wanting to learn more about the connections between the moon and the practice of magic.

For decades, books, movies, television shows, and conspiracy theories have speculated about the existence of life on other planets. But how possible is it that we are alone in the universe? How likely is it we’ll find a habitable, Earth-like planet? How come we have not already seen signs of extraterrestrial life? Join astrophysicist Sarah Rugheimer to reveal what we know about detecting life on other planets.

In Into the Unknown, astrophysicist Kelsey Johnson takes us to the edge of scientific understanding about the universe: What caused the Big Bang? What happens inside black holes? Are there other dimensions? She doesn’t just celebrate what we know but rather what we don’t, and asks what it means if we never find that knowledge. Exploring the convergence of science, philosophy, and theology, Johnson argues we must reckon with possibilities—including those that may be beyond human comprehension.

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.

Every generation has looked up from the Earth and wondered at the beauty of the moon. 50 years ago, a few Americans became the first to do the reverse - with the whole world watching through their eyes. In this short but wide-ranging book, Oliver Morton explores the history and future of humankind's relationship with the moon. A counterpoint in the sky, it has shaped our understanding of the Earth from Galileo to Apollo. Its gentle light has spoken of love and loneliness; its battered surface of death and the cosmic.

For centuries, people have speculated about the possibility of planets orbiting distant stars, but only since the 1990s has technology allowed astronomers to detect them. At this point, more than five thousand such exoplanets have been identified, with the pace of discovery accelerating after the launch of NASA’s Transiting Exoplanet Satellite Survey and the Webb Space Telescope. In The Little Book of Exoplanets, Princeton astrophysicist Joshua Winn offers a brief and engaging introduction to the search for exoplanets and the cutting-edge science behind recent findings.

In a drastic reevaluation of astronomy observations from Mahabharata, using high-tech tools of modern astronomy and low-tech tools of the logic of scientific discovery, Nilesh Oak’s extraordinary book presents ordinary theory of astronomy observations that would lead to a quantum jump in our understanding of the Mahabharata War

Have you ever wondered how we came into being? Have you ever looked in the sky, marveled by the stars? This book is a friendly and accessible guide to our universe, our galaxy, our solar system, and the planet we call home. If you are an aspiring astronomer or someone who wishes to know more about the topic, this is the perfect book. It is not just for astronomers. Any layman or someone who is intrigued by the universe, planets, stars, and the like will be capable of understanding this book.

Elon Musk founded SpaceX with the mission of making humans a multiplanetary species. In the coming years, SpaceX will launch a crew of 24 people through space and onto Mars, in a new kind of rocket called Starship. Over 80 million miles away, Mars is both desolate, and at the same time, full of limitless potential. Mars holds limitless possibilities. Since the ideal alignment for Earth and Mars only happens once every two years, there is only a small window to get everything right.

Our universe has been growing for nearly 14 billion years. But almost everything about it, from the elements that forged stars, planets, and lifeforms, to the fundamental forces of physics, can be traced back to what happened in just the first three minutes of its existence. In this book, Nobel Laureate Steven Weinberg describes in wonderful detail what happened in these first three minutes.

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.

Using the power of the sun, moon, stars, and planets, this unique guide is filled with engaging exercises that deepen your knowledge of the solar system, help you take necessary pauses every day, and foster a renewed sense of presence in the universe.

Light of the Stars is science at the grandest of scales, and it tells a radically new story about what we are: one world in a universe awash in planets. Building on his widely discussed scientific papers and New York Times op-eds, astrophysicist Adam Frank shows that not only is it likely that alien civilizations have existed many times before, but also that many of them have driven their own worlds into dangerous eras of change.
