    Jo Marchant's book can begin to heal it. For at least 20,000 years, we have led not just an earthly existence but a cosmic one. Celestial cycles drove every aspect of our daily lives. Our innate relationship with the stars shaped who we are--our art, religious beliefs, social status, scientific advances, and even our biology. But over the last few centuries we have separated ourselves from the universe that surrounds us. It's a disconnect with a dire cost.Our relationship to the stars and planets has moved from one of awe, wonder and superstition to one where technology is king--the cosmos is now explored through data on our screens, not by the naked eye observing the natural world. Indeed, in most countries modern light pollution obscures much of the night sky from view. Jo Marchant's spellbinding parade of the ways different cultures celebrated the majesty and mysteries of the night sky is a journey to the most awe inspiring view you can ever see--looking up on a clear dark night. That experience and the thoughts it has engendered have radically shaped human civilization across millennia. The cosmos is the source of our greatest creativity in art, in science, in life.To show us how, Jo Marchant takes us to the Hall of the Bulls in the caves at Lascaux in France, and to the summer solstice at a 5,000-year-old tomb at New Grange in England. We discover Chumash cosmology and visit medieval monks grappling with the nature of time and Tahitian sailors navigating by the stars. We discover how light reveals the chemical composition of the sun, and we are with Einstein as he works out that space and time are one and the same. A four-billion-year-old meteor inspires a search for extraterrestrial life. The cosmically liberating, summary revelation is that star-gazing made us human.

    For a shorter trip on a tight budget, the Moon is quite majestic and very quiet if you can make it during the off-season. With four-color illustrations and packed with real-world science, The Vacation Guide to the Solar System is the must-have planning guide for the curious space adventurer, covering all of the essentials for your next voyage, how to get there, and what to do when you arrive. Written by an astronomer from The American Museum of Natural History and one of the creators of the Guerilla Science collective, this tongue-in-cheek reference guide is an imaginative exploration into the What if of space travel, sharing fascinating facts about space, the planets in our solar system, and even some moons!"

    With the Big Bang, it went 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 dark matter to black holes to one rocky planet orbiting a star near the edge of a spiral galaxy that happened to develop life. But what happens at the end of the story? In billions of years, humanity could still exist in some unrecognizable form, venturing out to distant space, finding new homes and building new civilizations. But the death of the universe is final. What might such a cataclysm look like? And what does it mean for us? Dr. Katie Mack has been contemplating these questions since she was eighteen, when her astronomy professor first informed her the universe could end at any moment, setting her on the path toward theoretical astrophysics. Now, with lively wit and humor, she unpacks them in The End of Everything, taking us on a mind-bending tour through each of the cosmos’ possible finales: the Big Crunch; the Heat Death; Vacuum Decay; the Big Rip; and the Bounce. In the tradition of Neil DeGrasse’s bestseller Astrophysics for People in a Hurry, Mack guides us through major concepts in quantum mechanics, cosmology, string theory, and much more, in a wildly fun, surprisingly upbeat ride to the farthest reaches of everything we know.

    Each object is plotted on a detailed, easy-to-use star map, and most of these sights can be found even in a light-polluted sky. Also included are four seasonal all-sky charts that help locate each highlight. You don't need fancy or expensive equipment to enjoy the wonders of the night sky. In fact, as even experienced star gazers know, to go beyond the naked-eye sky and delve deep into the universe, all you need are binoculars ? even the ones hanging unused in your closet. If you don't own any, Binocular Highlights explains what to look for when choosing binoculars for star gazing and provides observing tips for users of these portable and versatile mini-telescopes. Sprial-bound with readable paper spine, full color throughout.

    Richard Gott leads time travel out of the world of H. G. Wells and into the realm of scientific possibility. Building on theories posited by Einstein and advanced by scientists such as Stephen Hawking and Kip Thorne, Gott explains how time travel can actually occur. He describes, with boundless enthusiasm and humor, how travel to the future is not only possible but has already happened, and he contemplates whether travel to the past is also conceivable. Notable not only for its extraordinary subject matter and scientific brilliance, Time Travel in Einstein’s Universe is a delightful and captivating exploration of the surprising facts behind the science fiction of time travel.

    These unabridged essays by Carl Sagan were originally published in either popular science magazines or academic journals. This is the first time his essays have become available on audio.

    In this book, Dr. Humphreys explains this phenomenon with his new cosmology including an easy-to-read popular summary and two technical papers.

    Along the way Stephen Baxter looks at our place in the universe, considers the possibility that we are in fact alone, and wonders whether that fact gives us the right to inherit everything. He also looks at how we might strive to overcome the limitations of the physical universe and win the deepest future. Stephen Baxter has brought his trademark narrative flair and imaginative brilliance to the latest ideas in physics and cosmology and produced a breathtaking guide to our possible futures.

    Can a computer think? Why is your consciousness like Bitcoin? Will there be an artificial intelligence apocalypse?

    A total eclipse of the Sun will be visible from within a narrow corridor that traverses the United States. The path of the Moon's umbral shadow will begin in the northern Pacific and cross the USA from west to east from Oregon to South Carolina. The Moon's penumbral shadow will produce a partial eclipse visible from most of North America. In fact, the 2017 full eclipse is such an important sky event that sky watchers in Europe are already planning trips to view it. 2017 Guide to the Night Sky provides all of the information needed to view this exciting eclipse and track its path. The time zones and transit of the eclipse will be noted inside the book's jacket for quick and easy reference.The night sky makes for exciting viewing any time of the year, and 2017 Guide to the Night Sky is the ideal guide to help amateur astronomers find their way for the entire 12 months. With monthly charts and other diagrams set for a latitude of 40 degrees North, it shows how the visible stars change from month to month and includes the many sky events that occur throughout the year. It is highly practical for beginning sky gazers because the objects and events may be observed with the naked eye, or nothing more complicated than a pair of binoculars.The month-by-month guides include sky activity charts and moon calendars; meteors (with dates of showers, including hourly rate of radiants); the Planets; ecliptic charts; diagrams of interesting events; plus sky and constellation maps throughout.An appendix includes a full glossary; the Greek Alphabet; the constellation genitives, abbreviations and English names; a table of common asterisms; further information; recommended astronomy journals, societies, institutions and organizations; software, and internet sources.Especially useful for beginning sky watchers, this guide will be fully updated to 2017. Its small and light format makes it the ideal portable reference for backyard astronomers.

    Plait created his popular web site: http://www.badastronomy.com/index.html, to debunk bad astronomy in popular culture. This website proved popular, which led to this first book by Plait, that carries on from the website and in a detailed and clear fashion criticises and disproves popular myths and misconceptions relating to astronomy, and promotes science as a means of explaining the skies. The work describes 24 common astronomical fallacies, including the beliefs that the Coriolis effect determines the direction that water drains in a bathtub, and that planetary alignments can cause disaster on Earth. The author sharply and convincingly dismisses astrology, creationism, and UFO sightings, and explains the principles behind basic general concepts (the Big Bang, why the sky is blue, etc.).

    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.   In Extraterrestrial, Loeb takes readers inside the thrilling story of the first interstellar visitor to be spotted in our solar system. He outlines his controversial theory and its profound implications: for science, for religion, and for the future of our species and 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.

    Large format diagrams show these objects exactly as they appear in a small telescope and for each object there is information on the current state of our astronomical knowledge. Revised and updated, this new edition contains a chapter with ten new spreads describing spectacular deep sky objects visible from the southern hemisphere, and tips on observing the upcoming transits of Venus. It also discusses Dobsonian telescopes, with hints on using personal computers and the Internet as aids for planning an observing session. Also new to this edition are redrawn Guidepost figures at the beginning of each season chapter that allow readers to visualize a three-dimensional view of the sky's dome; redesigned seasonal object layouts that provide more space for the naked-eye charts; a new spread on double stars near Bo�tes has been added to Spring, replacing the Shrinking Double spread; and a unique When and Where to Look table has been added to the last page, among other new features. Unlike many guides to the night sky, this book is specifically written for observers using small telescopes. Clear and easy to use, this fascinating book will appeal to skywatchers of all ages and backgrounds. No previous knowledge of astronomy is needed.

    Thus began one of the boldest scientific projects in history, the Search for Extraterrestrial Intelligence (SETI). But after a half century of scanning the skies, astronomers have little to report but an eerie silence—eerie because many scientists are convinced that the universe is teeming with life. The problem, argues the leading physicist-astrobiologist Paul Davies, is that we’ve been looking in the wrong place, at the wrong time & in the wrong way. Davies should know. For more than three decades, he's been closely involved with SETI & now chairs its Post-Detection Taskgroup, charged with deciding what to do if we’re confronted with evidence of alien intelligence. In this extraordinary book, he shows how SETI has lost its edge & offers a new exciting road map for the future. Davies believes our search so far has been overly anthropocentric: we tend to assume an alien species will look, think & behave like us. He argues that we need to be far more expansive in our efforts, & in this book he completely redefines the search, challenging existing ideas of what form an alien intelligence might take, how it might try to communicate with us & how we should respond if it does. A provocative & mind-expanding journey, The Eerie Silence will thrill fans of science & science fiction alike.
