In late 2017, scientists at a Hawaiian observatory glimpsed an object soaring through our inner solar system, moving so quickly that it could only have come from another star. Avi Loeb, Harvard’s top astronomer, showed it was not an asteroid; it was moving too fast along a strange orbit, and left 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.

Everyone is curious about life in the Universe, UFOs and whether ET is out there. Over the course of his thirty-year career as an astrophysicist, Adam Frank has consistently been asked about the possibility of intelligent life in the universe. Are aliens real? Where are they? Why haven’t we found them? What happens if we do?

In the final book of his astonishing career, Carl Sagan brilliantly examines the burning questions of our lives, our world, and the universe around us. These luminous, entertaining essays travel both the vastness of the cosmos and the intimacy of the human mind, posing such fascinating questions as how did the universe originate and how will it end, and how can we meld science and compassion to meet the challenges of the coming century?

Sean Carroll, theoretical physicist and one of this world’s most celebrated writers on science, rewrites the history of 20th-century physics. Already hailed as a masterpiece, Something Deeply Hidden shows for the first time that facing up to the essential puzzle of quantum mechanics utterly transforms how we think about space and time. His reconciling of quantum mechanics with Einstein’s theory of relativity changes, well, everything. Most physicists haven’t even recognized the uncomfortable truth: Physics has been in crisis since 1927.

In our unique genomes, every one of us carries the story of our species - births, deaths, disease, war, famine, migration, and a lot of sex. But those stories have always been locked away - until now. Who are our ancestors? Where did they come from? Geneticists have suddenly become historians, and the hard evidence in our DNA has completely upended what we thought we knew about ourselves. Acclaimed science writer Adam Rutherford explains exactly how genomics is completely rewriting the human story - from 100,000 years ago to the present.

Since its 2009 launch, the Kepler satellite has discovered more than 2,000 exoplanets, or planets outside our solar system. More exoplanets are being discovered all the time, remarkable in their variety. Astronomer Michael Summers and physicist James Trefil explore these remarkable recent discoveries: planets revolving around pulsars, planets made of diamond, planets that are mostly water, and numerous rogue planets wandering through the emptiness of space.

The Skeptics' Guide to the Universe is your map through this maze of modern life. Here Dr. Steven Novella and friends will explain the tenets of skeptical thinking and debunk some of the biggest scientific myths, fallacies, and conspiracy theories - from anti-vaccines to homeopathy, UFO sightings to N-rays. You'll learn the difference between science and pseudoscience, essential critical thinking skills, ways to discuss conspiracy theories with that crazy co-worker of yours, and how to combat sloppy reasoning, bad arguments, and superstitious thinking.

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.

Stephen Hawking not only unraveled some of the universe's greatest mysteries but also believed science plays a critical role in fixing problems here on Earth. Now, as we face immense challenges on our planet - including climate change, the threat of nuclear war, and the development of artificial intelligence - he turns his attention to the most urgent issues facing us. Will humanity survive? Should we colonize space? Does God exist? These are just a few of the questions Hawking addresses in this wide-ranging, passionately argued final book from one of the greatest minds in history.

We know the universe had a beginning. With the Big Bang, it expanded from a state of unimaginable density to an all-encompassing cosmic fireball to a simmering fluid of matter and energy, laying down the seeds for everything from black holes to one rocky planet orbiting a star near the edge of a spiral galaxy that happened to develop life as we know it. But what happens to the universe at the end of the story? And what does it mean for us now?

Drawing on his decades of field research and up-to-the-minute understanding of the latest science, renowned geologist Andrew H. Knoll delivers a rigorous yet accessible biography of Earth, charting our home planet's epic 4.6 billion-year story. Placing 21st-century climate change in deep context, A Brief History of Earth is an indispensable look at where we’ve been and where we’re going.

The runaway success of the microchip may finally be reaching its end. As shrinking transistors approach the size of atoms, the phenomenal growth of computational power inevitably collapses. But this change heralds the birth of a revolutionary new type of computer, one that calculates on atoms themselves. Quantum computers promise unprecedented gains in computing power, enabling advancements that could overturn every aspect of our daily lives.

Mercury, a lifeless victim of the Sun’s expanding power. Venus, once thought to be lush and fertile, now known to be trapped within a toxic and boiling atmosphere. Mars, the red planet, doomed by the loss of its atmosphere. Jupiter, twice the size of all the other planets combined, but insubstantial. Saturn, a stunning celestial beauty, the jewel of our Solar System. Uranus, the sideways planet and the first ice giant. Neptune, dark, cold and whipped by supersonic winds. Pluto, the dwarf planet, a frozen rock.

Carl Sagan, writer and scientist, returns from the frontier to tell us about how the world works. In his delightfully down-to-earth style, he explores and explains a mind-boggling future of intelligent robots, extraterrestrial life and its consequences, and other provocative, fascinating quandaries of the future that we want to see today.

Not only can we not currently explain the origin of the universe, it is questionable we will ever be able to explain it. The notion that there are universes within particles, or that particles are conscious, is ascientific, as is the hypothesis that our universe is a computer simulation. On the other hand, the idea that the universe itself is conscious is difficult to rule out entirely.

This new and long-awaited sequel to Carl Sagan's international best seller continues the electrifying journey through space and time, linking worlds within and worlds billions of miles away and envisioning a future of science tempered with wisdom. Based on National Geographic's internationally-renowned television series, this groundbreaking and visually stunning book explores how science and civilization grew up together.

Les Johnson takes you on a thrilling tour of the physics and technologies that may enable us to reach the stars. He discusses the latest exoplanet discoveries, promising interstellar missions on the not-so-distant horizon, and exciting new developments in space propulsion, power, robotics, communications, and more. But interstellar travel will not be easy, and it is not for the faint of heart. Johnson describes the harsh and forbidding expanse of space that awaits us, and he addresses the daunting challenges that we need to overcome in order to realize tomorrow's possibilities.

Long before space travel was possible, the idea of life beyond Earth transfixed humans. In this fascinating book, astronomer Jon Willis explores the science of astrobiology and the possibility of locating other life in our own galaxy. Describing the most recent discoveries by space exploration missions, including the Kepler space telescope, the Mars Curiosity rover, and the New Horizons probe, Willis asks listeners to imagine - and choose among-five scenarios for finding life.

In The Universe, today's most influential science writers explain the science behind our evolving understanding of The Universe and everything in it, including the cutting-edge research and discoveries that are shaping our knowledge. Lee Smolin reveals how math and cosmology are helping us create a theory of the whole universe. Neil Turok analyzes the fundamental laws of nature, what came before the big bang, and the possibility of a unified theory. And much more.

There are deep connections between stars and atoms, between the cosmos and the microworld. Just six numbers, imprinted in the "Big Bang", determine the essential features of our entire physical world. Moreover, cosmic evolution is astonishingly sensitive to the values of these numbers. If any one of them were "untuned", there could be no stars and no life. This realization offers a radically new perspective on our universe, our place in it, and the nature of physical laws.

The Big Bang is all but dead, and we do not yet know what will replace it. Our universe's "beginning" is at an end. What does this have to do with us here on Earth? Our lives are about to be dramatically shaken again - as altered as they were with the invention of the clock, the steam engine, the railroad, the radio and the Internet.

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.

Everyone is curious about life in the Universe, UFOs and whether ET is out there. Over the course of his thirty-year career as an astrophysicist, Adam Frank has consistently been asked about the possibility of intelligent life in the universe. Are aliens real? Where are they? Why haven’t we found them? What happens if we do?

The hunt for the Higgs particle has involved the biggest, most expensive experiment ever. So exactly what is this particle? Why does it matter so much? What does it tell us about the universe? Was finding it really worth all the effort? The short answer is yes. The Higgs field is proposed as the way in which particles gain mass - a fundamental property of matter. It's the strongest indicator yet that the Standard Model of physics really does reflect the basic building blocks of our universe. Little wonder the hunt and discovery of this new particle produced such intense media interest.

On October 4, 1957, the Soviet Union launched Sputnik I, and the space race was born. Desperate to beat the Russians into space, NASA put together a crew of the nation's most daring test pilots: the seven men who were to lead America to the moon. The first into space was Alan Shepard; the last was Deke Slayton, whose irregular heartbeat kept him grounded until 1975. They spent the 1960s at the forefront of NASA's effort to conquer space, and Moon Shot is their inside account of what many call the 20th century's greatest feat - landing humans on another world.

Throughout history, scientists have come up with theories and ideas that just don't seem to make sense. These we call paradoxes. The paradoxes Al-Khalili offers are drawn chiefly from physics and astronomy and represent those that have stumped some of the finest minds. With elegant explanations that bring the listener inside the mind of those who've developed them, Al-Khalili helps us to see that, in fact, paradoxes can be solved if seen from the right angle.

When we think of electricity, we likely imagine the energy humming inside our home appliances or lighting up our electronic devices - or perhaps we envision the lightning-streaked clouds of a stormy sky. But electricity is more than an external source of power, heat, or illumination. Life at its essence is nothing if not electrical.

Rules of the quantum world seem to say that a cat can be both alive and dead at the same time and a particle can be in two places at once. And that particle is also a wave; everything in the quantum world can described in terms of waves - or entirely in terms of particles. These interpretations were all established by the end of the 1920s, by Erwin Schrödinger, Werner Heisenberg, Paul Dirac, and others. But no one has yet come up with a common sense explanation of what is going on.

Earth evolves. From first atom to molecule, mineral to magma, granite crust to single cell to verdant living landscape, ours is a planet constantly in flux. In this radical new approach to Earth’s biography, senior Carnegie Institution researcher and national best-selling author Robert M. Hazen reveals how the co-evolution of the geosphere and biosphere - of rocks and living matter - has shaped our planet into the only one of its kind in the Solar System, if not the entire cosmos.
