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, with little regard for scientific accuracy, in several Hollywood movies.

Astrophysicist and science writer Andrew May disentangles fact from fiction in this fast-moving and entertaining account, covering the nature and history of comets and asteroids, the reason why some orbits are more hazardous than others, the devastating local and global effects that an impact event would produce, and – more optimistically – the way future space missions could avert a catastrophe.

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.

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."

Can you spot the Big Dipper in the night sky? Or Orion's Belt? Or Cassiopeia? Even in cities, and without the aid of a telescope, these are a few of the easier constellations to find. In fact, a great deal can be seen in the night sky with the naked eye - if you know what you're looking for. Night Sky presents 200 colour photographs of stunning nocturnal vistas all visible to the naked eye. From the majesty of the Northern Lights (Aurora borealis) as seen from Norway or Canada, and the Southern Lights (Aurora australis) as seen from Australia, to seeing the clarity of the Milky Way over an Italian forest, from witnessing a lunar eclipse in Indonesia to charting the course of the International Space Station across the Indian night, and from seeing a Geminid meteor shower in New Mexico to recognizing the Great Bear (Ursa Major) constellation over New England, the book is a feast of nocturnal delights. Where necessary, additional inset photographs indicate the formation of a constellation. Presented in a landscape format and with 200 outstanding colour photographs supported by fascinating captions, Night Sky is a stunning collection of images.

Meteorites are among the rarest objects on Earth, yet they have left a pervasive mark on our planet and civilization. Arriving amidst thunderous blasts and flame-streaked skies, meteorites were once thought to be messengers from the gods, embodiments of the divine. Prized for their outlandish qualities, meteorites are a collectible, a commodity, objects of art and artists' desires and a literary muse. 'Meteorite hunting' is an adventurous, lucrative profession for some, and an addictive hobby for thousands of others. Meteorite: Nature and Culture is a unique, richly illustrated cultural history of these ancient and mysterious phenomena. Taking in a wide range of sources Maria Golia pays homage to the scientists, scholars and aficionados who have scoured the skies and combed the Earth's most unforgiving reaches for meteorites, contributing to a body of work that situates our planet and ourselves within the vastness of the Universe.Appealing to collectors and hobbyists alike, as well as any lovers of nature, marvel and paradox, this book offers an accessible overview of what science has learned from meteorites, beginning with the scientific community's reluctant embrace of their interplanetary origins, and explores their power to reawaken that precious, yet near-forgotten human trait - the capacity for awe.

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.

Between 1969 and 1972, twelve people walked on the surface of the Moon. Twelve others flew over its barren and majestic surface. They were the sons of workers, farmers, soldiers and businessmen. They thought anything was possible-and they proved this to the entire world. For 20 years, Lukas Viglietti, an airline pilot and captain, has been fascinated by the conquest of the astronauts who went to space during his childhood. He has recorded their testimonies and since becoming their friend and confidant, he now offers an exclusive and unprecedented insight into their adventures. In APOLLO CONFIDENTIAL, adults and children alike experience the all-inspiring accounts of: steely-eyed test pilots sensitive painters and poets hard-living bad boys thoughtful, studious scientists The only thing they had in common was they all saw the view of the beautiful home planet from a quarter of a million miles away, an oasis of life compared to the stark and lifeless, alien moon. In APOLLO CONFIDENTIAL, Lukas Viglietti recounts what people from the history books-people such as Neil Armstrong and Buzz Aldrin-were like in person.

In a world divided by the ideological struggles of the Cold War, the Vietnam War and the Civil Rights Movement, more than one-fifth of the people on the planet paused to watch the live transmission of the Apollo 11 mission. To watch as humanity took a giant leap forward. A companion book to the landmark documentary series on BBC TV. The journey from Cape Canaveral to the Moon was a tremendous achievement of human courage and ingenuity. It was also a long, deadly march, haunted by the possibility of catastrophic failure on the world's stage. In an era when the most advanced portable computer weighed 70 pounds, had a 36-kilobite memory and operated on less power than a 60-watt lightbulb, the sheer audacity of the goal is breath-taking. But the triumph of imagination and the unity of the Earth that day would change the world. Based on eyewitness accounts and newly discovered archival material, Chasing the Moon reveals the unknown stories of the individuals who made the Moon landing a possibility, from inspirational science fiction writer Arthur C. Clark and controversial engineer Wernher von Braun, to pioneers like mathematician Poppy Northcutt and astronaut Edward Dwight. It vividly revisits the dawn of the Space Age, a heady time of scientific innovation, political calculation, media spectacle, visionary impulses and personal drama.

It has been the aim of the authors to give in this book a brief, simple, and accurate account of the heavens as they are known to astronomers of the present day. It is believed that there is nothing in the book beyond the comprehension of readers of ordinary intelligence, and that it contains all the information on the subject of astronomy that is needful to a person of ordinary culture. The authors have carefully avoided dry and abstruse mathematical calculations, yet they have sought to make clear the methods by which astronomers have gained their knowledge of the heavens. The various kinds of telescopes and spectroscopes have been described, and their use in the study of the heavens has been fully explained.

For twenty-five years following the Voyager mission, scientists speculated about Saturn's largest moon, a mysterious orb clouded in orange haze. Finally, in 2005, the Cassini-Huygens probe successfully parachuted down through Titan's atmosphere, all the while transmitting images and data. In the early 1980s, when the two Voyager spacecraft skimmed past Titan, Saturn's largest moon, they transmitted back enticing images of a mysterious world concealed in a seemingly impenetrable orange haze. "Titan Unveiled" is one of the first general interest books to reveal the startling new discoveries that have been made since the arrival of the Cassini-Huygens mission to Saturn and Titan.

Ralph Lorenz and Jacqueline Mitton take readers behind the scenes of this mission. Launched in 1997, Cassini entered orbit around Saturn in summer 2004. Its formidable payload included the Huygens probe, which successfully parachuted down through Titan's atmosphere in early 2005, all the while transmitting images and data--and scientists were startled by what they saw. One of those researchers was Lorenz, who gives an insider's account of the scientific community's first close encounter with an alien landscape of liquid methane seas and turbulent orange skies. Amid the challenges and frayed nerves, new discoveries are made, including methane monsoons, equatorial sand seas, and Titan's polar hood. Lorenz and Mitton describe Titan as a world strikingly like Earth and tell how Titan may hold clues to the origins of life on our own planet and possibly to its presence on others.

Generously illustrated with many stunning images, "Titan Unveiled" is essential reading for anyone interested in space exploration, planetary science, or astronomy.

A new afterword brings readers up to date on Cassini's ongoing exploration of Titan, describing the many new discoveries made since 2006.
