Tiny pieces of space rock called micrometeorites are everywhere on Earth. In Search of Stardust shows you how to find them! The solar system is a dusty place. Every day approximately 100 metric tons of cosmic dust collides with Earth, mainly in the form of micrometeorites. Most of these mineral particles (iron, nickel, etc.) are smaller than grains of sand, and they are falling down on us all the time and all over the globe. Still, little is known about these exotic extraterrestrials. In Search of Stardust is the first comprehensive popular science book about micrometeorites. It's also a photo documentary comprising more than 1,500 previously unpublished images: the first atlas of micrometeorites, hundreds of which are depicted here in high-resolution color microscopic photography and in scanning electron microscope imagery. Author Jon Larsen shows readers how and where to look for micrometeorites, explains the history of micrometeoritics, and offers chapters about micrometeorite formation, classification, and analysis. Thanks to Larsen's work, for the first time it is now possible for anyone to find these amazing tiny stones from space. For more than a century it was believed these incredible space objects could be found only in pristine, unsullied environs like Antarctica and ocean floors. Larsen became the first to break the code and find micrometeorites in populated areas -- in fact, they can be found in the nearest rain gutter. In the book Larsen explains how anyone with a bit of inexpensive equipment can find their own micrometeorites. It was recently discovered that King Tut's dagger was forged from a chunk of a meteorite. What else is made of extraterrestrial rock? Join the hunt!

This volume gives an historical overview of the development of professional optical and radio observatories from 1945 to today. It covers the environment in which these facilities were developed by organisations in the United States, Europe and elsewhere, often led by larger-than-life individuals, as well as exploring the financial and political factors that both constrained and encouraged progress. As ever more expensive optical facilities were built, they exploited new technologies to significantly improve their performance: CCDs, active and adaptive optics, and spun honeycomb and segmented mirrors. The second half of this volume turns to the parallel history of radio astronomy facilities throughout the world, finishing with the ALMA observatory in Chile. This is the ground-based companion to the author's previous work on space astronomy, New Cosmic Horizons (2001). It is written for both technical and non-technical readers interested in the modern history of astronomy and its observational facilities.

A thorough understanding of planktonic organisms is the first step towards a real appreciation of the diversity, biology, and ecological importance of marine life. A detailed knowledge of their distribution and community composition is particularly important since these organisms are often very delicate and sensitive to change, and can be used as early indicators of environmental change. Natural and man-induced modification of the environment can affect both the distribution and composition of plankton, with important ecological and economic impacts. Marine Plankton provides a practical guide to plankton biology with a large geographic coverage spanning the North Sea to the north-eastern Atlantic coast of the USA and Canada. The book is divided into three sections: an overview of plankton ecology, an assessment of methodology in plankton research covering sampling, preservation, and counting of samples, and a taxonomic guide richly illustrated with detailed line drawings to aid identification. This is an essential reference text suitable for senior undergraduate and graduate students taking courses in marine ecology (particularly useful for fieldwork) as well as for professional marine biologists. It will also be of relevance and use to environmental scientists, conservation biologists, marine resource managers, environmental consultants, and other specialised practitioners.

Beautifully illustrated with over 140 full colour images, The Cambridge Encyclopedia of Meteorites provides a thorough guide to these fascinating extraterrestrial rocks. Meteorites are our only contact with materials from beyond the Earth-Moon system. Using well known petrologic techniques, this book reveals in vivid colour their extraordinary external and internal structures. Looking deeper still, right to the atomic level, they begin to tell us of the environment within the solar nebula that existed before the planets accreted. In recent years, meteorites have caught the imagination of scientist and collector alike. An army of people are now actively searching for them in the hot and cold deserts of Earth. This book is a valuable guide to assist the searchers in the field to recognize the many classes of meteorites. It is further a reference source for students, teachers and scientists who wish to probe deeper these amazing rocks from space.

Featuring detailed commented spectral profiles of more than one hundred astronomical objects, in colour, this spectral guide documents most of the important and spectroscopically observable objects accessible using typical amateur equipment. It allows you to read and interpret the recorded spectra of the main stellar classes, as well as most of the steps from protostars through to the final stages of stellar evolution as planetary nebulae, white dwarfs or the different types of supernovae. It also presents integrated spectra of stellar clusters, galaxies and quasars, and the reference spectra of some terrestrial light sources, for calibration purposes. Whether used as the principal reference for comparing with your recorded spectra or for inspiring independent observing projects, this atlas provides a breathtaking view into our Universe's past. The atlas is accompanied and supplemented by Spectroscopy for Amateur Astronomers, which explains in detail the methods for recording, processing, analysing and interpreting your spectra.

Over 500 color images and engaging text provide insight into these interesting collectibles from "out of this world." Meteorites link back to the early stages of the Milky Way galaxy and are the oldest items one can touch, some dating back to before the creation of our solar system. Meteorites are also among the most primitive forms of matter you can closely observe and handle. Some of these ambassadors from the void were created in stars that no longer exist. Others provide the curious researcher with original material from the earliest days of our own solar system. These rocks tell tales to those who know how to read them of nebulas, novas, supernovas, red giants, and impacting celestial bodies. Readers can explore metallic, stony-iron, and stony meteorites, meteorite falls, Northwest African meteorites, and rare meteorites.

Drilling For Meteorites is the untold story of Meteor Crater in 1920-21 when it was a lonely, isolated mining camp. Bitter cold in the winter, broiling heat in the summer, and roaring winds were just some of the troubles a hearty band of drillers faced in their attempt to find the buried star under the crater rim. Led by mining superintendent L. F. S. Holland they fought a battle with a natural wonder, Earth's first impact crater to be investigated. Their saga was preserved in the papers saved by Mr. Holland. Many of the features seen at Meteor Crater today have their origin in the one year that L. F. S. Holland was in charge. The tunnel and tailing pile on the south wall, the buildings on the south slope, the actual drilling site where 5,500 tons of rock were removed are just a few of the remains from 1920-21 which survive. This and much more is revealed in detail in Drilling for Meteorites.
