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?

Space is a place of unparalleled possibility for humanity, and it's undergoing a revolution. A wave of companies led by gutsy entrepreneurs are unlocking opportunities that fire the imagination. No, it's not hotels on Mars or day trips to orbit (yet), but it's an awe-inspiring transformation driven by innovative technologies, creative approaches, hard work, and—for the first time—market forces.

How big is the universe? In the early twentieth century, scientists took sides. One held that the entire universe was contained in the Milky Way galaxy. Their champion was the strong-willed astronomer Harlow Shapley. Another camp believed that the universe was so vast that the Milky Way was just one galaxy among billions—the view that would prevail, proven by the equally headstrong Edwin Hubble.

Jacobson provides a comprehensive overview of the space industry, allowing everyone to understand the role space plays in our lives and how it will continue to transform the world. Over 100 industry experts and leaders share insights, presenting a 360-degree view of the wide-ranging space industry, its emerging opportunities, investment potential, and benefits.

After a few billion years of bearing witness to life on Earth, of watching one hundred billion humans go about their day-to-day lives, of feeling unbelievably lonely, and of hearing its own story told by others, The Milky Way would like a chance to speak for itself. All one hundred billion stars and fifty undecillion tons of gas of it. It all began some thirteen billion years ago, when clouds of gas scattered through the universe's primordial plasma just could not keep their metaphorical hands off each other.

Throughout history, when threatened by wildfires our only defense was to pray for rain and run—until aircraft changed the way we fight fires. Beginning with the Canadian "H-Boats" in 1924, aircraft have become indispensable in detecting and extinguishing wildfires. Fire Eaters tells the incredible stories of the Ontario Provincial Air Service, the first government aerial fire suppression organization in history; one of its pilots, Carl Crossley, who invented the water scoop-up and drop-off system; and the Canadair CL-215, the first purpose-built water bomber.

In Strange New Worlds, renowned astronomer Ray Jayawardhana brings news from the front lines of the epic quest to find planets—and alien life—beyond our solar system. Only in the past two decades, after millennia of speculation, have astronomers begun to discover planets around other stars—thousands in fact. Now they are closer than ever to unraveling distant twins of the Earth. In this book, Jayawardhana vividly recounts the stories of the scientists and the remarkable breakthroughs that have ushered in this extraordinary age of exploration.

Through more than 50 Koans - pleasingly paradoxical vignettes following the ancient Zen tradition - leading physicist Anthony Aguirre takes the listener across the world from West to East, and through ideas spanning the age, breadth, and depth of the Universe. Using these beguiling Koans (Could there be a civilization on a mote of dust? How much of your fate have you made?

Did you know that humans have only been able to study five percent of the universe? The other 95 percent of our universe is invisible! There are several parts of the universe that we haven't seen yet, as light from there hasn't reached us yet! If the mechanisms of space pique your interest, you have come to the right place.

In this thrilling history, David Baker captures the longest possible time span—from the Big Bang to the present day—in an astonishingly concise retelling. His impressive timeline includes the "rise of complexity" in the cosmos and the creation of the first atoms; the origin of all galaxies, stars, and our solar system; and the evolution of life on Earth, from tiny single-celled organisms to human beings.

Discover the science behind the most popular sci-fi franchise of all time. Capturing the imagination and hearts of crowds worldwide, Star Wars is a fantastic feat of science fiction and fantasy. We marvel at the variety of creatures and technology and the mystery behind the force. But how much of the Star Wars world is rooted in reality? Could we see some of the extraordinary inventions materialize in our world?

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.

Qu’il vive en ville, à la campagne, en Europe, en Afrique, au xxie siècle ou il y a plus de 2 000 ans, l’être humain lève les yeux vers le ciel pour essayer de trouver des réponses à des questions existentielles. Notre histoire commune a engendré nos savoirs, et c'est cette épopée que je veux raconter ici. Cette odyssée est aussi la mienne, et j'en propose un récit personnel, intime.

On July 23, 1999, the Chandra X-Ray Observatory, the most powerful X-ray telescope ever built, was launched aboard the space shuttle Columbia. Since then, Chandra has given us a view of the universe that is largely hidden from telescopes sensitive only to visible light. In Chandra's Cosmos, Wallace H. Tucker uses a series of short, connected stories to describe the telescope's exploration of the hot, high-energy face of the universe.

The Russell Cosmogony: A New Concept of Light, Matter, and Energy by Walter Russell offers a revolutionary perspective on the workings of the universe, challenging conventional scientific paradigms. This groundbreaking work explores the principles of light, matter, energy, electricity, and magnetism through a unique lens, emphasizing the unity and rhythmic balance of all creation.

David K. Stumpf demystifies the intercontinental ballistic missile program that was conceived at the end of the Eisenhower administration as a key component of the US nuclear strategy of massive retaliation. Although its nuclear warhead may have lacked power relative to that of the Titan II, the Minuteman more than made up for this in terms of numbers and readiness to launch - making it the ultimate ICBM.

Instruments of modern physics can measure the energies of the electromagnetic spectrum, but these energies only account for roughly 4 percent of the total identifiable mass-energy of the universe. What makes up the remaining 96%? In this scientifically based yet accessible analysis, Yury Kronn, Ph.D., explores the nature of the remaining 96% of the universe’s mass-energies. Contemporary science calls this mass energy “dark matter,” and the ancients called it life force, prana, or chi.

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.

When Neil Armstrong and Buzz Aldrin stepped onto the lunar surface in July of 1969, they wore spacesuits made by Playtex: 21 layers of fabric, each with a distinct yet interrelated function, custom-sewn for them by seamstresses whose usual work was fashioning bras and girdles. This book is the story of that spacesuit. It is a story of the triumph over the military-industrial complex by the International Latex Corporation, best known by its consumer brand of "Playtex" - a victory of elegant softness over engineered hardness, of adaptation over cybernetics.

Full of exclusive new stories, and astonishing detail only an astronaut would know, the book conveys what space exploration is really like: the wondrous view of Earth, the surreal weightlessness, the extraordinary danger, the surprising humdrum, the unexpected humour, the newfound perspective, the years of training, the psychological pressures, the gruelling physical toll, the thrill of launch and the trepidation of re-entry. The book also examines the surprising, shocking and often poignant stories of astronauts back on Earth, whose lives are forever changed as they readjust to terra firma.
