Astronomers believe that a supernova is a massive explosion signaling the death of a star, causing a cosmic recycling of the chemical elements and leaving behind a pulsar, black hole, or nothing at all. In an engaging story of the life cycles of stars, Laurence Marschall tells how early astronomers identified supernovae, and how later scientists came to their current understanding, piecing together observations and historical accounts to form a theory, which was tested by intensive study of SN 1987A, the brightest supernova since 1006. He has revised and updated "The Supernova Story" to include all the latest developments concerning SN 1987A, which astronomers still watch for possible aftershocks, as well as SN 1993J, the spectacular new event in the cosmic laboratory.

With plans to launch hotels into orbit and experiments in suspending and reanimating life for ultra-long-distance travel, private companies and entrepreneurs have outpaced NASA as the leaders in the new space race. With accessible prose and relentless curiosity, Chris Impey reports on China's plan to launch its own space station by 2020, proves that humans could survive on Mars and unveils cutting-edge innovations such as the space elevators poised to replace rockets at a fraction of the cost. Setting mankind's urge towards exploration in the context of all human history and space travel thus far, he shows that the present-day scientists mapping billions of Earth-like exo-planets are the descendants of the first humans to venture out of Africa. We must forge ahead, argues Beyond, because exploration is in our DNA.

This first comprehensive history of the Kennedy Space Center, NASA's famous launch facility located at Cape Canaveral, Florida, reveals the vital but largely unknown work that takes place before the rocket is lit. Though the famous Vehicle Assembly Building and launch pads dominate the flat Florida landscape at Cape Canaveral and attract 1.5 million people each year to its visitor complex, few members of the public are privy to what goes on there beyond the final outcome of the flaring rocket as it lifts into space. With unprecedented access to a wide variety of sources, including the KSC archives, other NASA centers, the National Archives, and individual and group interviews and collections, Lipartito and Butler explore how the methods and technology for preparing, testing, and launching spacecraft have evolved over the last 45 years. Their story includes the Mercury and Gemini missions, the Apollo lunar program, the Space Shuttle, scientific missions and robotic spacecraft, and the International Space Station, as well as the tragic accidents of Challenger and Columbia. Throughout, the authors reveal the unique culture of the people who work at KSC and make Kennedy distinct from other parts of NASA.As Lipartito and Butler show, big NASA projects, notably the Space Shuttle and the International Space Station, had much to learn on the ground before they made it to space. Long before a spacecraft started its ascent, crucial work had been done, work that combined the muscular and mundane with the high tech and applied the vital skills and knowledge of the men and women of KSC to the design of vehicles and missions. The authors challenge notions that successful innovation was simply the result of good design alone and argue that, with large technical systems, real world experience actually made the difference between bold projects that failed and innovations that stayed within budget and produced consistent results. The authors pay particular attention to "operational knowledge" developed by KSC--the insights that came from using and operating complex technology. This work makes it abundantly clear that the processes performed by ground operations are absolutely vital to success.

Es geschah vor nicht langer Zeit, daB ein deutscher Phy siker im Vorwort eines kleinen Buches liber ein aktuelles physikalisches Gebiet dem Verleger besonders dankte, weil er die Arbeit so beschleunigt hatte, daB das Buch nicht wahrend des Druckes veraItete. Dies ist fur das Arbeitstempo der modernen Physik be zeichnend, und es konnte unter gewissen Umstanden das selbe fUr die Astronomie sein. 'Wenn der Unterzeichnete wahrend des Druckes der vorliegenden kleinen Arbeit keine ernsthaften Sorgen in derselben Richtung wie sein Kollege in der Physik zu haben brauchte, so liegt das im wesent lichen daran, daB das Buch Probleme aus der klassischen Astronomie behandeIt. Doch auf einen Punkt muB ich in diesem Zusammenhang die Aufmerksamkeit lenken: die Eddingtonsche Theorie yom inneren Bau der Sterne ist in der letzten Zeit so groBen Veranderungen ausgesetzt ge wesen, daB die Schilderung, die ich in meinen vorhedgen Buchern "Astronomische Miniaturen" (das Kapitel Scylla und Charybdis) und "Die Hauptprobleme der modernen Astronomie" davon gegeben habe, jetzt als teilweise veraltet angesehen werden muB. In der vorliegenden Arbeit ist der Gegenstand unter Berucksichtigung der letzten Entwick lungsphasen behandelt. Die Verfasser haben bei der Ausarbeitung dieses kleinen Buches an dem Programm der "Astronomischen Minia turen" festgehaIten: die Einteilung in eine Reihe kleiner - IV- Kapitel, die fiir einen wesentlichen Teil ganz unabhangig voneinander sind."

From our own solar system to the edges of the universe, 50 Astronomy Ideas You Really Need to Know is your introduction to the most important concepts, discoveries and mysteries in astronomy. How did the universe begin? Where did the Moon come from? What happens in the heart of a black hole? Why are gravitational waves so significant? And is there life elsewhere in the cosmos? In fifty fascinating essays covering the central ideas of astronomy and cosmology, accompanied by diagrams, definitions of essential terms and timelines of key discoveries, this book examines the nature and variety of our universe - the life cycle of stars, the formation of planets, the structure of galaxies and the puzzles of dark matter and the multiverse. Expansive and illuminating, 50 Astronomy Ideas You Really Need to Know is the complete guide to the birth, life and possible death of the cosmos.

Although space travel has been a topic of great interest to many, few have an understanding of the ultimate limits that will determine its possibilities. One thing is certain. No matter the advancement in technology, whether earthling or extraterrestrial, energy requirements will determine ultimate success in space travel. True, technology will play a part. Among other things, it will determine the kinds of fuels that will be useable in deep space travel and that will, in the end, determine its successes.
Are we ultimately going to be able to travel outside our own solar system to reach other worlds? Have extraterrestrials really visited us in the past? These are the questions addressed in this book. It is written for the layman, and does not require a technical background.

What happens when a star dies? How many asteroids are in our solar system? Can galaxies collide? What is dark energy? Astronomy in Minutes answers all these questions and more as it condenses 200 key concepts into easily digestible essays. From Trojan asteroids to stellar black holes, and from superclusters to cosmic microwave background, this book will take you on an essential tour around the universe. Beginning with the specks and constellations that we see in the night sky, and then zooming in on the objects and 'matter' beyond the naked eye, Astronomy in Minutes draws on established theories and recent research. Each essay is accompanied by an image or a clear diagram to help unravel complex ideas. Beginning with the constellations and finishing with the latest cosmological theories, this is the perfect reference guide to this fascinating subject. Contents include: The celestial sphere, Piscis Austrinus, the Earth-Moon system, Io and Ganymede, Kuiper Belt Objects, Measuring stellar properties, Nuclear fusion, Red and orange dwarfs, Open star clusters, Planetary nebulae, Supernova remnants, Cosmic expansion, Quasars and blazars, Nature of spacetime, Nucleosynthesis and the Anthropic Principle.

Master outdoorsman Tristan Gooley was just about to make camp when he sensed danger--but couldn't say why. After sheltering elsewhere, Gooley returned to investigate: What had set off his subconscious alarm?

Suddenly, he understood: All of the tree trunks were slightly bent. The ground had already shifted once and could easily become treacherous in a storm.

The Nature Instinct shows how we, too, can unlock this intuitive understanding of our surroundings. Learn to sense the forest's edge from deep in the woods, or whether a wild animal might pose danger--before you even know how you know.

Publisher's note: The Nature Instinct was published in the UK under the title Wild Signs and Star Paths.
