In Part 1, the book describes the very latest thinking on solar physics in (mostly non-mathematical) detail, incorporating the latest results from research concerning the structure and behaviour of the Sun. There is particular emphasis on the surface features visible from the Earth, and how these are the result of the extraordinary processes that are taking place within the Sun.

In Part 2, the book details the techniques for observing and imaging the Sun with commercially-available equipment. The many recent advances in optical equipment now allow amateur astronomers to observe phenomena that until recently could only be seen with the extremely expensive equipment available at universities and research observatories notably H-alpha and Calcium-K telescopes.

This is a completely up-to-date solar observing book, while providing the science background necessary for an understanding of the observations with the latest equipment. It also features the most complete solar observing and imaging guide available."

Mars, like planet Earth, is a complex and vast world with a long history. The authors of this book give a new insight of Mars by adopting an original outline based on history rather than on subtopic (atmosphere, surface, interior). They focus on the past and present evolution of Mars and also incorporate all the recent results from the space missions of Mars Express, Spirit and Opportunity.

This book goes to the heart of current planetological research, and illustrates it with many beautiful images. The authors describe the magnificent scenery on Mars including Olympus Mons, more than 20,000 metres high and the solar systema (TM)s biggest volcano. At Marsa (TM) poles, glaciers, formed from thousands of fine strata, are evidence of past climatic fluctuations. Drs Forget and Costard and Professor LognonnA(c) introduce a new world and reveal the workings of the planet Mars. They answer the questions: How was Mars formed? Why has its evolution followed a different path to that of Earth? What do its river beds, volcanoes and glaciers tell us about its past? Could life have existed there? Does it exist there now? What processes a ~drivea (TM) Mars today?

The five parts of the book trace the history of Mars. Part 1 examines its formation from the ashes of dead stars, more than 4A-5 billion years ago. Part 2 travels through its early and turbulent youth and gradual, 3A-5-billion-year long metamorphosis. Part 3 traces the creation of great planetary structures while Part 4 explores this active planet as it is today, with its dust storms, water features and atmosphere, and shows that Mars is subject to continual climatic change. Finally in Part 5, the story of the recent exploration ofMars and current research in laboratories and space agencies in preparation for the missions of the next twenty years is recounted.

The detection and exploration of extrasolar planets is one of the most exciting and fast moving areas of astronomical research at the present time. With over forty research programmes ongoing, and just as many planned, the search for these new worlds has become the main objective for a new generation of giant ground-based telescopes as well as many future space missions. Experimental methods and observational techniques are pushing existing instruments to their limits. The most exciting possibility offered by this research is the discovery of Earth-like extrasolar planets, with a mass comparable to that of Earth, located at the right distance from its star to host liquid water - in other words, a place where life could evolve. The authors tackle this challenging field of research by first looking at early searches for extrasolar planets, the very first discoveries and the observational techniques involved. They, then examine the very wide range of extrasolar planets that have been discovered during the past ten years and look at what we can learn about such planets by studying the bodies in our own solar system.The formation of planetary systems, the way in which such systems may evolve and the final systems of planets that result are then discussed. Finally, Drs Casoli and Encrenaz examine the possibilities for life on extrasolar planets, again using our own solar system as a model, and look to the plans for future extrasolar planet searches. A number of Appendices summarise the extrasolar planet discoveries to date.

The Moon: Resources, Future Development and Settlement describes feasible human settlement of the Moon in the coming century. Small scale, tele-operated and autonomous robotic in-situ resource utilization (ISRU) projects are first, followed by electric power, communication, and transportation networks manufactured from lunar resources. These infrastructure networks are field tested an commissioned in the polar regions of the Moon, and permanent human settlements are then established. Through several phases of development, the utility networks grow, and the number of permanently inhabited bases increases to inculde all areas of interest on the Moon. The book stresses that the envisioned "Planet Moon Project" will link the technological and cultural expertise of humanity to the virtually limitless resources of space. From that beginning, the people of the Earth reap substatntial benefits from space, and the human species will evolve into a spacefaring civilization.

Mars has long been believed to have been cold, dead and dry for eons, but there is now striking new proof that not only was Mars a relatively warm and wet place in geologically recent times, but that even today there are vast reserves of water frozen beneath the planet's surface. As well as casting fascinating new insights into Mars' past, this discovery is also forcing a complete rethink about the mechanisms of global planetary change and the possibility that there is microbial life on Mars. David Harland considers the issue of life on Mars in parallel with the origin of life on Earth. At the time the Viking instruments were designed, it was thought that all terrestrial life ultimately derived its energy from sunlight, and that the earliest form of life was the cyanobacteria with chlorophyll for photosynthesis. It was assumed the same would be the case on Mars and that microbial life would be on or near the surface that the Vikings had sampled.

Solar science has evolved rapidly over the past ten years as the results of a new generation of solar space missions have become available. This book provides a thorough introduction to the subject of solar physics, based on those spacecraft observations. The author introduces the solar corona, which has a temperature of several million degrees, and sets it in the context of basic plasma physics before moving on to discuss plasma instabilities and plasma heating processes. The latest results on coronal heating and radiation, which are fundamental processes in all stars, are presented. Spectacular phenomena such as solar flares and coronal mass ejections are described in detail, together with their potential effects on the Earth. The author draws together observations made at many wavelengths from hard X-rays, soft X-rays, extreme UV and radio wavelengths.

This paperback study edition of Markus Aschwanden s highly acclaimed Physics of the Solar Corona will include 50 pages of problems and solutions which will much enhance the value of the book to students."

R2,008 Discovery Miles 20 080 Ships in 18 - 22 working days

The purpose of this book is to illustrate the fundamental concepts of complexity and complex behavior and the best methods to characterize this behavior by means of their applications to some current research topics from within the fields of fusion, earth and solar plasmas. In this sense, it is a departure from the many books already available that discuss general features of complexity. The book is divided in two parts. In the first part the most important properties and features of complex systems are introduced, discussed and illustrated. The second part discusses several instances of possible complex phenomena in magnetized plasmas and some of the analysis tools that were introduced in the first part are used to characterize the dynamics in these systems. A list of problems is proposed at the end of each chapter. This book is intended for graduate and post-graduate students with a solid college background in mathematics and classical physics, who intend to work in the field of plasma physics and, in particular, plasma turbulence. It will also be of interest to senior scientists who have so far approached these systems and problems from a different perspective and want a new fresh angle.

Impact! The Threat of Comets and Asteroids (Paperback, Revised): Gerrit L. Verschuur Impact! The Threat of Comets and Asteroids (Paperback, Revised)
Gerrit L. Verschuur
R543 Discovery Miles 5 430 Ships in 10 - 15 working days

Most scientists now agree that some sixty-five million years ago, an immense comet slammed into the Yucatan, detonating a blast twenty million times more powerful than the largest hydrogen bomb, punching a hole ten miles deep in the earth. Trillions of tons of rock were vaporized and launched into the atmosphere. For a thousand miles in all directions, vegetation burst into flames. There were tremendous blast waves, searing winds, showers of molten matter from the sky, earthquakes, and a terrible darkness that cut out sunlight for a year, enveloping the planet in freezing cold. Thousands of species of plants and animals were obliterated, including the dinosaurs, some of which may have become extinct in a matter of hours. In Impact, Gerrit L. Verschuur offers an eye-opening look at such catastrophic collisions with our planet. Perhaps more important, he paints an unsettling portrait of the possibility of new collisions with earth, exploring potential threats to our planet and describing what scientists are doing right now to prepare for this awful possibility.
Every day something from space hits our planet, Verschuur reveals. In fact, about 10,000 tons of space debris fall to earth every year, mostly in meteoric form. The author recounts spectacular recent sightings, such as over Allende, Mexico, in 1969, when a fireball showered the region with four tons of fragments, and the twenty-six pound meteor that went through the trunk of a red Chevy Malibu in Peekskill, New York, in 1992 (the meteor was subsequently sold for $69,000 and the car itself fetched $10,000). But meteors are not the greatest threat to life on earth, the author points out. The major threats are asteroids and comets. The reader discovers that astronomers have located some 350 NEAs ("Near Earth Asteroids"), objects whose orbits cross the orbit of the earth, the largest of which are 1627 Ivar (6 kilometers wide) and 1580 Betula (8 kilometers). Indeed, we learn that in 1989, a bus-sized asteroid called Asclepius missed our planet by 650,000 kilometers (a mere six hours), and that in 1994 a sixty-foot object passed within 180,000 kilometers, half the distance to the moon. Comets, of course, are even more deadly. Verschuur provides a gripping description of the small comet that exploded in the atmosphere above the Tunguska River valley in Siberia, in 1908, in a blinding flash visible for several thousand miles (every tree within sixty miles of ground zero was flattened). He discusses Comet Swift-Tuttle--"the most dangerous object in the solar system"--a comet far larger than the one that killed off the dinosaurs, due to pass through earth's orbit in the year 2126. And he recounts the collision of Comet Shoemaker-Levy 9 with Jupiter in 1994, as some twenty cometary fragments struck the giant planet over the course of several days, casting titanic plumes out into space (when Fragment G hit, it outshone the planet on the infrared band, and left a dark area at the impact site larger than the Great Red Spot). In addition, the author describes the efforts of Spacewatch and other groups to locate NEAs, and evaluates the idea that comet and asteroid impacts have been an underrated factor in the evolution of life on earth.
Astronomer Herbert Howe observed in 1897: "While there are not definite data to reason from, it is believed that an encounter with the nucleus of one of the largest comets is not to be desired." As Verschuur shows in Impact, we now have substantial data with which to support Howe's tongue-in-cheek remark. Whether discussing monumental tsunamis or the innumerable comets in the Solar System, this book will enthrall anyone curious about outer space, remarkable natural phenomenon, or the future of the planet earth.

Meteorites and Their Parent Planets provides an engrossing overview of a highly interdisciplinary field--the study of extraterrestrial materials. The second edition of this successful book has been thoroughly revised, and describes the nature of meteorites, where they come from, and how they get to Earth. Meteorites offer important insights into processes in stars and in interstellar regions, the birth of our solar system, the formation and evolution of planets and smaller bodies, and the origin of life. The first edition was immensely popular with meteorite collectors, scientists and science students in many fields, as well as amateur astronomers. In this second edition all of the illustrations have been updated and improved, many sections have been expanded and modified based on discoveries in the past decade, and a new final chapter on the importance of meteorites has been added. Everyone with an interest in meteorites will want a copy of this book.

R535 Discovery Miles 5 350 Ships in 10 - 15 working days

In 1961, only a few weeks after Alan Shepherd completed the first American suborbital flight, President John F. Kennedy announced that the U.S. would put a man on the moon before the end of the decade. The next year, NASA awarded the right to meet the extraordinary challenge of building a lunar excursion module to a small airplane company called Grumman from Long Island, New York.

Chief engineer Thomas J. Kelly gives a firsthand account of designing, building, testing, and flying the Apollo lunar module. It was, he writes, "an aerospace engineer's dream job of the century". Kelly's account begins with the imaginative process of sketching solutions to a host of technical challenges with an emphasis on safety, reliability, and maintainability. He catalogs numerous test failures, including propulsion-system leaks, ascent-engine instability, stress corrosion of the aluminum alloy parts, and battery problems, as well as their fixes under the ever-present constraints of budget and schedule. He also recaptures the anticipation of the first unmanned lunar module flight with Apollo 5 in 1968, the exhilaration of hearing Apollo 11's Neil Armstrong report that "The Eagle has landed", and the pride of having inadvertently provided a vital "lifeboat" for the crew of the disabled Apollo 13.

From researching and writing the contract-winning proposal through six successful moon landings and returns, Kelly provides a compelling look at the protean efforts of the nearly 7,000 Grumman workers who together created the most important component of the first manned spaceflights.

R1,740 Discovery Miles 17 400 Ships in 18 - 22 working days

Whereas conventional maps can be expressed as outward-expanding formulae with well-defined central features and relatively poorly defined edges, Constant Scale Natural Boundary (CSNB) maps have well-defined boundaries that result from natural processes and thus allow spatial and dynamic relationships to be observed in a new way useful to understanding these processes. CSNB mapping presents a new approach to visualization that produces maps markedly different from those produced by conventional cartographic methods. In this approach, any body can be represented by a 3D coordinate system. For a regular body, with its surface relatively smooth on the scale of its size, locations of features can be represented by definite geographic grid (latitude and longitude) and elevation, or deviation from the triaxial ellipsoid defined surface. A continuous surface on this body can be segmented, its distinctive regional terranes enclosed, and their inter-relationships defined, by using selected morphologically identifiable relief features (e.g., continental divides, plate boundaries, river or current systems). In this way, regions of distinction on a large, essentially spherical body can be mapped as two-dimensional 'facets' with their boundaries representing regional to global-scale asymmetries (e.g., continental crust, continental and oceanic crust on the Earth, farside original thicker crust and nearside thinner impact punctuated crust on the Moon). In an analogous manner, an irregular object such as an asteroid, with a surface that is rough on the scale of its size, would be logically segmented along edges of its impact-generated faces. Bounded faces are imagined with hinges at occasional points along boundaries, resulting in a foldable 'shape model.' Thus, bounded faces grow organically out of the most compelling natural features. Obvious boundaries control the map's extremities, and peripheral regions are not dismembered or grossly distorted as in conventional map projections. 2D maps and 3D models grow out of an object's most obvious face or terrane 'edges,' instead of arbitrarily by imposing a regular grid system or using regularly shaped facets to represent an irregular surface.

Philosophers and poets in times past tried to figure out why the stainless moon "smoothly polished, like a diamond" in Dante's words, had stains. The agreed solution was that, like a mirror, it reflected the imperfect Earth. Today we smile, but it was a clever way to understand the Moon in a manner that was consistent with the beliefs of their age. The Moon is no longer the "in" thing. We see it as often as the Sun and give it little thought - we've become indifferent. However, the Moon does reflect more than just sunlight. The Moon, or more precisely the nomenclature of lunar craters, still holds up a mirror to an important aspect of human history. Of the 1586 craters that have been named honoring philosophers and scientists, only 28 honor a woman. These 28 women of the Moon present us with an opportunity to meditate on this gap, but perhaps more significantly, they offer us an opportunity to talk about their lives, mostly unknown today.

The Babylonian Theory of the Planets (Paperback): N.M. Swerdlow The Babylonian Theory of the Planets (Paperback)

R1,581 Discovery Miles 15 810 Ships in 18 - 22 working days

In the second millennium b.c., Babylonian scribes assembled a vast collection of astrological omens, believed to be signs from the gods concerning the kingdom's political, military, and agricultural fortunes. The importance of these omens was such that from the eighth or seventh until the first century, the scribes observed the heavens nightly and recorded the dates and locations of ominous phenomena of the moon and planets in relation to stars and constellations. The observations were arranged in monthly reports along with notable events and prices of agricultural commodities, the object being to find correlations between phenomena in the heavens and conditions on earth. These collections of omens and observations form the first empirical science of antiquity and were the basis of the first mathematical science, astronomy. For it was discovered that planetary phenomena, although irregular and sometimes concealed by bad weather, recur in limited periods within cycles in which they are repeated on nearly the same dates and in nearly the same locations.

N. M. Swerdlow's book is a study of the collection and observation of ominous celestial phenomena and of how intervals of time, locations by zodiacal sign, and cycles in which the phenomena recur were used to reduce them to purely arithmetical computation, thereby surmounting the greatest obstacle to observation, bad weather. The work marks a striking advance in our understanding of both the origin of scientific astronomy and the astrological divination through which the kingdoms of ancient Mesopotamia were governed.

Simone Marchi presents the emerging story of how cosmic collisions shaped both the solar system and our own planet, from the creation of the Moon to influencing the evolution of life on Earth. The Earth emerged out of the upheaval and chaos of massive collisions in the infancy of the Solar System, more than four billion years ago. The largest of these events sent into orbit a spray of molten rocks out of which the Moon coalesced. As in ancient mythological tales, this giant catastrophe marks the birth of our planet as we know it. Space exploration has shown that signs of ancient collisions are widespread in the Solar System, from the barren and once-habitable Mars to the rugged asteroids. On Earth these signs are more subtle, but still cataclysmic, such as the massive asteroid strike which likely sparked the demise of the dinosaurs and many other forms of life some 66 million years ago. Signatures of even more dramatic catastrophes are concealed in ancient rocks. These events wreaked havoc on our planet's surface, influencing global climate and topography, while also enriching the Earth with gold and other rare elements. And recently, modern science is finding that they could even have contributed to developing the conditions conducive to life. In Colliding Worlds, Simone Marchi explores the key role that collisions in space have played in the formation and evolution of our solar system, the development of planets, and possibly even the origin of life on Earth. Analysing our latest understanding of the surfaces of Mars and Venus, gleaned from recent space missions, Marchi presents the dramatic story of cosmic collisions and their legacies.
