Ever since its infancy, humankind has been seeking answers to some very basic and profound questions. Did the Universe begin? If it did, how old is it, and where did it come from? What is its shape? What is it made of? Fascinating myths and brilliant in- itions attempting to solve such enigmas can be found all through the history of human thought. Every culture has its own legends, itsownworldcreationtales, itsphilosophicalspeculations, itsre- gious beliefs. Modern science, however, cannot content itself with fanciful explanations, no matter how suggestive they are. No- days, our theories about the Universe, built upon rational ded- tion, have to survive the hard test of experiment and observation. Cosmology, the science which studies the origin and evo- tion of the Universe, had to overcome enormous dif?culties before it could achieve the same level of dignity as other physical dis- plines. At ?rst, it had no serious physical model and mathematical tools that could be used to address the complexity of the problems it had to face. Then, it suffered from a chronic lack of experim- tal data, which made it almost impossible to test the theoretical speculations. Given this situation, answering rigorously the many questions on the nature of the Universe seemed nothing more than a delusion. Today, however, things have changed. We live in the golden age of cosmology: an exciting moment, when, for the ?rst time, we are able to scienti?cally understand our Univers

A sweeping account of the century of experimentation that confirmed Einstein's general theory of relativity, bringing to life the science and scientists at the origins of relativity, the development of radio telescopes, the discovery of black holes and quasars, and the still unresolved place of gravity in quantum theory. Albert Einstein did nothing of note on May 29, 1919, yet that is when he became immortal. On that day, astronomer Arthur Eddington and his team observed a solar eclipse and found something extraordinary: gravity bends light, just as Einstein predicted. The finding confirmed the theory of general relativity, fundamentally changing our understanding of space and time. A century later, another group of astronomers is performing a similar experiment on a much larger scale. The Event Horizon Telescope, a globe-spanning array of radio dishes, is examining space surrounding Sagittarius A*, the supermassive black hole at the center of the Milky Way. As Ron Cowen recounts, the foremost goal of the experiment is to determine whether Einstein was right on the details. Gravity lies at the heart of what we don't know about quantum mechanics, but tantalizing possibilities for deeper insight are offered by black holes. By observing starlight wrapping around Sagittarius A*, the telescope will not only provide the first direct view of an event horizon-a black hole's point of no return-but will also enable scientists to test Einstein's theory under the most extreme conditions. Gravity's Century shows how we got from the pivotal observations of the 1919 eclipse to the Event Horizon Telescope, and what is at stake today. Breaking down the physics in clear and approachable language, Cowen makes vivid how the quest to understand gravity is really the quest to comprehend the universe.

ESCAPE FROM EARTH is the untold story of the engineers, dreamers and rebels who started the American space programme. In particular, it is the story of Frank Malina, founder of what became Nasa's Jet Propulsion Laboratory and the scientist who cracked the, as he called it, problem of escape from the Earth by rocket.

It's a wild ride. Jack Parsons, Malina's chemistry-expert research partner, was a bed-hopping occultist with delusions of grandeur. We get all the horrible details: drug parties and sex magic, cameos by Aleister Crowley and L Ron Hubbard, and an ill-fated attempt to start a mail-order religion.

Armed with hitherto unpublished letters, journals, and documents from the Malina family archives, Fraser MacDonald reveals what we didn't know. Jack Parsons betrayed Frank Malina to the FBI, cooperating fully in their investigation of Malina for un-American activities. The Jet Propulsion Lab's second director secretly denounced Frank as a Communist. Frank's research group had close ties to the spy network of the infamous Rosenbergs - the only Americans executed during the Red Scare. This is a story of soaring ideals entangled in the most human of complications: infidelity and divorce, betrayal and treason.

Harvard's top astronomer takes us inside the mind-blowing story of the first interstellar visitor to our solar system.

In late 2017, scientists at a Hawaiian observatory glimpsed a strange object soaring through our inner solar system. Astrophysicist Avi Loeb conclusively showed it was not an asteroid; it was moving too fast along a strange orbit, and leaving no trail of gas or debris in its wake. There was only one conceivable explanation: the object was a piece of advanced technology created by a distant alien civilization.

In Extraterrestrial, Loeb takes readers inside the thrilling story of the first interstellar visitor to be spotted in our solar system. He outlines his theory and its profound implications: for science, for religion, and for the future of our planet. A mind-bending journey through the furthest reaches of science, space-time, and the human imagination, Extraterrestrial challenges readers to aim for the stars-and to think critically about what's out there, no matter how strange it seems.

This book explains how it came to be that Venus and Earth, while very similar in chemical composition, zonation, size and heliocentric distance from the Sun, are very different in surface environmental conditions. It is argued here that these differences can be accounted for by planetoid capture processes and the subsequent evolution of the planet-satellite system. Venus captured a one-half moon-mass planetoid early in its history in the retrograde direction and underwent its "fatal attraction scenario" with its satellite (Adonis). Earth, on the other hand, captured a moon-mass planetoid (Luna) early in its history in prograde orbit and underwent a benign estrangement scenario with its captured satellite.

NASA's history is a familiar story, one that typically peaks with Neil Armstrong taking his small step on the Moon in 1969. But America's space agency wasn't created in a vacuum. It was assembled from pre-existing parts, drawing together some of the best minds the non-Soviet world had to offer. In the 1930s, rockets were all the rage in Germany, the focus both of scientists hoping to fly into space and of the German armed forces, looking to circumvent the restrictions of the Treaty of Versailles. One of the key figures in this period was Wernher von Braun, an engineer who designed the rockets that became the devastating V-2. As the war came to its chaotic conclusion, von Braun escaped from the ruins of Nazi Germany, and was taken to America where he began developing missiles for the US Army. Meanwhile, the US Air Force was looking ahead to a time when men would fly in space, and test pilots like Neil Armstrong were flying cutting-edge, rocket-powered aircraft in the thin upper atmosphere. Breaking the Chains of Gravity tells the story of America's nascent space program, its scientific advances, its personalities and the rivalries it caused between the various arms of the US military. At this point getting a man in space became a national imperative, leading to the creation of the National Aeronautics and Space Administration, otherwise known as NASA.

What is Mars? From the ancients to the present, we have imagined Mars repeatedly and studied it longingly. As scientific knowledge of Mars has changed, so has the cultural imagination of this celestial neighbors. The earth-centered beginnings of astronomy connected the blood-red planet with the God of War. The Copernican Revolution and a later, simple mistranslation from Italian supported fantastic visions of distant Mars as the abode of life variously bizarre, ideal, or malignant. In the work of H. G. Wells and Orson Welles, in books, films, radio, and television, Mars reflected not only eternal hopes and fears but then-current political realities. In recent years, "NASA-fication" has brought Mars home, imagining the Red Planet almost as an eighth continent of Earth, a candidate for exploration and exploitation both in fiction and in fact. Rabkin weaves a chronological tale of many threads, including mythology, astrology, astronomy, literary criticism, and cultural studies. More than 60 brief chapters focus on people, events, or phenomena concerning the eternal object of curiosity, Mars. This rich series of readable, illustrated chapters can be sampled at will for the fun of discovery, read sequentially as a connected history, or enjoyed as a resource for the contemplation. Featuring over 100 illustrations, this unique examination of humanity's most storied companion serves as a resource for the study of ourselves.

For most of human history, we have had a close relationship with the stars. Once they shaped our religious beliefs, power structures, scientific advances and even our biology. But over the last few centuries we have separated ourselves from the universe that surrounds us. And it comes at a cost. The Human Cosmos is a tour of this history: from the Hall of the Bulls in Lascaux to Tahitian sailors navigating by the stars; from medieval monks grappling with the nature of time to Einstein realising that space and time are the same. It shows we need to rediscover the universe we inhabit, its effect on our health, and its potential for inspiration and revelation.

Of all the natural disasters that could befall us, only an Earth impact by a large comet or asteroid has the potential to end civilization in a single blow. Yet these near-Earth objects also offer tantalizing clues to our solar system's origins, and someday could even serve as stepping-stones for space exploration. In this book, Donald Yeomans introduces readers to the science of near-Earth objects--its history, applications, and ongoing quest to find near-Earth objects before they find us. In its course around the sun, the Earth passes through a veritable shooting gallery of millions of nearby comets and asteroids. One such asteroid is thought to have plunged into our planet sixty-five million years ago, triggering a global catastrophe that killed off the dinosaurs. Yeomans provides an up-to-date and accessible guide for understanding the threats posed by near-Earth objects, and also explains how early collisions with them delivered the ingredients that made life on Earth possible. He shows how later impacts spurred evolution, allowing only the most adaptable species to thrive--in fact, we humans may owe our very existence to objects that struck our planet. Yeomans takes readers behind the scenes of today's efforts to find, track, and study near-Earth objects. He shows how the same comets and asteroids most likely to collide with us could also be mined for precious natural resources like water and oxygen, and used as watering holes and fueling stations for expeditions to Mars and the outermost reaches of our solar system.

Journeys to the Ends of the Universe presents a tour through the universe from the big bang onward. The book explores the limits of knowledge where scientific fact overtakes and merges with the wilder speculations of science fiction. The beginnings of galaxies, stars, planets, and even life itself are related back to the raveled turmoil of the first few seconds and years of life in the cosmos. The journey continues past the ultimate fate of the solar system to probe the nature of supernovae. The future of galaxies, clusters of galaxies, super-clusters of clusters of galaxies, and so on leads toward the finale, where the author provides some bizarre musings of physicists and astronomers, suggesting possible destinies for the universe stretching its present age billions of times into the future.

Superb photographs, star charts, and graphics complement the text. This is a book for anybody who has ever gazed in wonder at the glory of a star-filled sky, a must for all amateur astronomers, and an interesting addition to the shelves of the experts.

A New Scientist Book of the Year A Physics Today Book of the Year A Science News Book of the Year The history of science is replete with women getting little notice for their groundbreaking discoveries. Cecilia Payne-Gaposchkin, a tireless innovator who correctly theorized the substance of stars, was one of them. It was not easy being a woman of ambition in early twentieth-century England, much less one who wished to be a scientist. Cecilia Payne-Gaposchkin overcame prodigious obstacles to become a woman of many firsts: the first to receive a PhD in astronomy from Radcliffe College, the first promoted to full professor at Harvard, the first to head a department there. And, in what has been called "the most brilliant PhD thesis ever written in astronomy," she was the first to describe what stars are made of. Payne-Gaposchkin lived in a society that did not know what to make of a determined schoolgirl who wanted to know everything. She was derided in college and refused a degree. As a graduate student, she faced formidable skepticism. Revolutionary ideas rarely enjoy instantaneous acceptance, but the learned men of the astronomical community found hers especially hard to take seriously. Though welcomed at the Harvard College Observatory, she worked for years without recognition or status. Still, she accomplished what every scientist yearns for: discovery. She revealed the atomic composition of stars-only to be told that her conclusions were wrong by the very man who would later show her to be correct. In What Stars Are Made Of, Donovan Moore brings this remarkable woman to life through extensive archival research, family interviews, and photographs. Moore retraces Payne-Gaposchkin's steps with visits to cramped observatories and nighttime bicycle rides through the streets of Cambridge, England. The result is a story of devotion and tenacity that speaks powerfully to our own time.

This book recounts the epic saga of how we as human beings have come to understand the Solar System. The story of our exploration of the heavens, Peter Bond reminds us, began thousands of years ago, with the naked-eye observations of the earliest scientists and philosophers. Over the centuries, as our knowledge and understanding inexorably broadened and deepened, we faltered many times, frequently labored under misconceptions, and faced seemingly insurmountable obstacles to understanding. Yet, despite overwhelming obstacles, a combination of determined observers, brilliant thinkers, courageous explorers, scientists and engineers has brought us, particularly over the last five decades, into a second great age of human discovery.

At our present level of understanding, some fifty years into the Space Age, the sheer volume of images and other data being returned to us from space has only increased our appetite for more and more detailed information about the planets, moons, asteroids, and comets of the Solar System. Taking a much-needed overview of how we now understand these "distant worlds" in our cosmic neighborhood, Bond not only celebrates the extraordinary successes of planetary exploration, but reaffirms an important truth: For seekers of knowledge, there will always be more to explore.

An astonishing saga of explorationa ]

In this much-needed overview of "where we stand today," Peter Bond describes the achievements of the astronomers, space scientists, and engineers who have made the exploration of our Solar System possible. A clearly written and compelling account of the Space Age, the book includes:

a [ Dramatic accounts of the daring, resourcefulness, andferocious competitive zeal of renowned as well as almost-forgotten space pioneers.

a [ Clear explanations of the precursors to modern astronomy, including how ancient natural philosophers and observers first took the measure of the heavens.

a [ More than a hundred informative photographs, maps, simulated scenarios, and technical illustrations--many of them in full color.

a [ Information-dense appendices on the physical properties of our Solar System, as well as a comprehensive list of 50 years of Solar System missions.

Organized into twelve chapters focused on the objects of our exploration (the individual planets, our Moon, the asteroids and comets), Bonda (TM)s text shows how the great human enterprise of space exploration may on occasion have faltered or wandered off the path, but taken as a whole amounts to one of the great triumphs of human civilization.

This book presents contributions from an internal symposium organized to celebrate the 80th anniversary of the Specola Vaticana, or Vatican Observatory, in the Papal Palace of Castel Gandolfo. The aim is to provide an overview of the scientific and cultural work being undertaken at the Observatory today and to describe the outcomes of important recent investigations. The contents cover interesting topics in a variety of areas, including planetary science and instrumentation, stellar evolution and stars, galaxies, cosmology, quantum gravity, the history of astronomy, and interactions between science, philosophy, and theology. On September 29, 1935, Pope Pius XI officially inaugurated the new headquarters of the Specola Vaticana at Castel Gandolfo. With new telescopes, a new astrophysical laboratory for spectrochemical analysis, and a young staff comprising Jesuit scientists, this inauguration marked the beginning of an intense period of scientific achievements at the Observatory. This anniversary book, featuring contributions from members of the current Observatory staff and adjunct scholars, will appeal to all with an interest in the history of the Specola Vaticana and its significance for astronomy.

This book introduces the reader to the wonders of Mars, covering all aspects from our past perceptions of the planet through to the latest knowledge on its history, its surface processes such as impact cratering, volcano formation, and glaciation, and its atmosphere and climate. In addition, a series of ten intriguing open issues are considered in a more advanced way. These include such thought-provoking questions as What turned off the planet's magnetic field?, Why are the northern and southern hemispheres so different?, What was the fate of the once abundant water?, and Is there, or was there, life on Mars? Numerous original figures, unavailable elsewhere, reproduce details of images from Viking, CTX, MOC, HiRISE, THEMIS, and HRSC. The book will appeal especially to general readers interested in planetary sciences, astronomy, astrogeology, and space exploration and to students of Earth Sciences and Natural and Environmental Sciences. The higher-level material on the remaining mysteries of Mars will also be of interest to astrogeologists and other researchers.
