This engaging memoir reveals the true story of the Search for ExtraterrestrialIntelligence (SETI), and discloses what we may very soon discover. Chronicling the program’s history with insight and humor, SETI senior astronomer Seth Shostak assures us that if there is sentient life in the universe, we are within decades of picking up its signal.

The heart of this course examines the planets themselves, and reveals how they are constructed and how they differ from one another. By studying the physical astronomy of all the planets in the Solar System, we can attempt to understand their true nature. Ultimately, these lectures will bring us to a greater understanding of the Solar System's creation, which brings us again back to the beginning and what it means to us as we look outward from our rotating Earth.

We’ve long understood black holes to be the points at which the universe as we know it comes to an end. Often billions of times more massive than the Sun, they lurk in the inner sanctum of almost every galaxy of stars in the universe. Recent research, however, has led to a cascade of new discoveries that have revealed an entirely different side to black holes. As the astrophysicist Caleb Scharf reveals in Gravity’s Engines, these chasms in space-time don’t just vacuum up everything that comes near them; they also spit out huge beams and clouds of matter.

A Journey Through the Universe is a grand tour of the most amazing celestial objects and how they fit together to build the cosmos. There's a whole universe out there.... Imagine you had a spacecraft capable of travelling through interstellar space. You climb in, blast into orbit, fly out of the solar system and keep going. Where do you end up, and what do you see along the way? The answer is: mostly nothing. Space is astonishingly, mind-blowingly empty.

Beginning with our earliest explorations of the night sky, William Waller takes us on an enthralling journey through the Milky Way and far, far beyond. He combines science and history to show how our understanding of everything from black holes to the structure of the universe has evolved over time, illuminating past discoveries and offering contemporary insights into the cosmic histories of stars, planets and galaxies. Whether object of study or curiosity, the universe – and all it contains – is tantalisingly introduced here.

In her graceful, compelling style, Dava Sobel chronicles the history of the Copernican Revolution, relating the story of astronomy from Aristotle to the Middle Ages. In its midst will be her play, And the Sun Stood Still, imagining the dialogue that would have transpired between Rheticus and Copernicus in their months together. As she achieved with her bestsellers Longitude and Galileo's Daughter, Sobel expands the bounds of science writing, giving us an unforgettable portrait of scientific achievement.

This Fleeting World tells the story of the universe and history of humanity. Prize-winning historian David Christian covers it all in this compact, accessible, and inspiring guide to the history of everything from stars and empires to cities to the World Wide Web, capitalism, and globalization. David Christian's approach to human history and big history is a call to action based on a profound and fresh understanding of our place in the universe.

Beneath the Night is a history of humanity, told through our relationship with the night sky. From prehistoric cave art and Ancient Egyptian zodiacs to the modern era of satellites and space exploration, Stuart Clark explores a fascination shared across the world and throughout millennia. It is one that has shaped our scientific understanding; helped us navigate the terrestrial world; provided inspiration for our poets, artists and philosophers; and it has given us a place to project our hopes and fears. In the stars, we can see our past - and ultimately, our fate.

Michael Schneider leads us on a spectacular journey along the numbers one through 10 to explore the mathematical principles made visible in flowers, shells, crystals, plants, and the human body, expressed in the symbolic language of folk sayings and fairy tales, myth and religion, art and architecture. This is a new view of mathematics, not the one we learned at school but a comprehensive guide to the patterns that recur through the universe and underlie human affairs.

Infinity Beckoned illuminates a critical period of space history when humans dared an expansive leap into the inner solar system. Jay Gallentine conveys the trials and triumphs of the people on the ground who conceived and engineered the missions that put robotic spacecraft on the heavenly bodies nearest our own.

In this updated, illustrated companion volume to Merlin's Tour of the Universe, we visit again with Merlin, a timeless space traveler from Planet Omniscia, who answers a collection of imaginative questions about the cosmos from Earthlings of all ages. Whether waxing poetic about Earth and its environs, the Sun and its stellar siblings, the world of light, physical laws or galaxies near and far, Merlin's remarks are engaging, humorous, and clear as a starry night sky.

Are there more than four dimensions to physical reality? Is it possible to traverse time as well as space? Is there a reality beyond our traditional concepts of time and space? The startling discovery of modern science is that our physical universe is actually finite. Scientists now acknowledge that the universe had a beginning. They call the singularity from which it all began the "Big Bang".

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.

A little over a century ago, a young Albert Einstein presented his general theory of relativity to the world and utterly transformed our understanding of the universe. His theory changed the way we think about space and time, revealed how our universe has been expanding from a hot, dense state called the big bang and predicted black holes. Where the Universe Came From is a 13.8 billiion-year journey through the cosmos.

For the first time in four billion years of life on Earth, we are preparing to step out among the stars, not just as lone astronauts or billionaire tech bros, but as a civilization. Dr Adriana Marais has dedicated her life to preparing form extraplanetary settlement, and here, she considers not just the scientific concerns of a multiplanetary existence (like terraforming and life-support systems), but also the ethical responsibilities we must carry with us as we explore new frontiers.

Scientists tell us that ninety-six percent of the universe is unexplained dark matter and dark energy. Also, they admit that no unifying “theory of everything” exists in physics. This shaky foundation is the basis of modern thinking about the cosmos and Earth’s place in it. Something big seems to be missing. Thus, we’re left with no choice but to question the “consensus” cosmological model. Are we really flying through space on a spinning ball within an expanding universe, while free-falling around the Sun—all as a consequence of a “Big Bang” that supposedly occurred 13.8 billion years ago?

As end-of-the-world scenarios go, an apocalyptic collision with an asteroid or comet is the new kid on the block, gaining respectability only in the last decade of the 20th century with the realisation that the dinosaurs had been wiped out by just such an impact. Now the science community is making up for lost time, with worldwide efforts to track the thousands of potentially hazardous near-Earth objects and plans for high-tech hardware that could deflect an incoming object from a collision course - a procedure depicted in several Hollywood movies.

The James Webb Space Telescope is transforming the universe right before our eyes—and here, for the first time, is the inside account of how the mission originated, how it performs its miracles of science, and what its revolutionary images are revealing. Pillars of Creation tells the story of one of the greatest scientific achievements in the history of civilization, a $10 billion instrument with a staggeringly ambitious goal: unlocking the secrets of the cosmos.

The possibility of life elsewhere in the cosmos is one of the most profound subjects that human beings can ponder. Astrophysicist Andrew May gives an expert overview of our current state of knowledge, looking at how life started on Earth, the tell-tale ‘signatures’ it produces and how such signatures might be detected elsewhere in the solar system or on the many ‘exoplanets’ now being discovered by the Kepler and TESS missions.

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.
