From Giza to Easter Island. The first complete and authoritative introduction to the young and fascinating science of Archaeoastronomy * Explores the ancients motives in constructing such grandiose buildings as the city of Teotihuacan or the Giza pyramids. * Illustrates how astronomy is key to understanding our ancestors way of thinking. * Uniquely studies the astronomical knowledge of our predecessors by analyzing their monuments. * Contains complete, up-to-date and extensive discussions of the exploration of the shafts in Cheops pyramid. Mysteries and Discoveries of Archaeoastronomy, Authors: Magli, Giulio This complete, authoritative study of the growing discipline of archaeoastronomy examines the role of astronomy in antiquity. Professor Guilio Magli provides a clear, up-to-date survey of current thinking on the motives of the ancients for building fabulous and mysterious monuments all over our planet. Was it an attempt to reproduce the sky on Earth? To bring down the power of the stars to where they could see it, worship it, and use it? The connecting thread is astronomy. Magli uses astronomy as a key to understanding our ancestors way of thinking. It is a challenge he likes to call "predicting the past." The motives of the ancients have often been misconstrued, maligned, or even dismissed. Magli shows the limitations of orthodox archaeology in relation to astronomically based artifacts and tries to understand what led the ancients to construct such magnificent structures as the city of Teotihuacan in the Mexico Valley, the Ceremonial Center of Chaco Canyon in the United States, the Avebury stone circle in Great Britain, and the great pyramids in Egypt. In this book, the reader is taken on a world tour of many wonderful and enigmatic places on almost every continent, in search of traces of astronomical knowledge and lore of the sky. Then, the author discusses the fundamental ideas that he believes led to the construction of the giant monuments. Finally, Magli revisits one place in greater detail Giza in an attempt to provide proof for his ideas on the mindset of ancient cultures. This fascinating book will take you places in time you have never been, and stimulate your imagination in regards to other people and other cultures. The result will be a better understanding of who we are and where we come from.

Titel: Choosing and Using Astronomical Filters Författare: Martin Griffiths Språk: Engelska Utgiven: 2015 Format: Häftad ISBN: 9781493910434Choosing and Using Astronomical Filters * Provides an in-depth look at the telescope accessories known as astronomical filters * Includes the history of different types of filters, their uses and specialist techniques * Features a basic guide to using Adobe Photoshop to further enhance images * Includes an observational guide to 100 astronomical objects that you can see better with filters, personally imaged by the author As a casual read through any of the major amateur astronomical magazines will demonstrate, there are filters available for all aspects of optical astronomy. This book provides a ready resource on the use of the following filters, among others, for observational astronomy or for imaging: * Light pollution filters * Planetary filters * Solar filters * Neutral density filters for Moon observation * Deep-sky filters, for such objects as galaxies, nebulae, and more Deep-sky objects can be imaged in much greater detail than was possible many years ago. Amateur astronomers can take photographs that rival those of professional observatories! The ability to do this has been brought about by the revolution in CCD cameras and improved filters. The book pinpoints which astronomical objects are best observed with which filters. Post-processing (using Photoshop) is also discussed, since it is helpful in further improving filtered astro images. The last part of the book is an observational guide to 100 deep sky objects that benefit from the use of filters – all personally observed by the author – with notes on the filters used (or potentially of use) in their observation and imaging. There are also notes on their celestial coordinates, magnitudes, and other pertinent information.

Titel: Digital SLR Astrophotography Författare: Michael A. Covington Språk: Engelska Format: Häftad ISBN: 9781316639931Digital SLR Astrophotography Digital SLR cameras have made it easier than ever before to photograph the night sky. Whether you're a beginner, nature photographer, or serious astronomer, this is the definitive handbook to capturing the heavens. Starting with simple projects for beginners such as cameras on tripods, it then moves onto more advanced projects including telescope photography and methods of astronomical research. With 80% revised and updated material, this new edition covers nightscapes, eclipses, using cameras with sky trackers and telescopes, and tools for identifying celestial objects and investigating them scientifically. Image processing is discussed in detail, with worked examples from three popular software packages - Nebulosity, Maxlm DL, and PixInsight. Rather than taking a recipe-book approach, Covington explains how your equipment works as well as offering advice on many practical considerations, such as choice of set-up and the testing of lenses, making this a comprehensive guide for anyone involved in astrophotography. * Amateurs with affordable, easily portable equipment now get better pictures of the sky than professional observatories did half a century ago * A comprehensive yet accessible handbook providing guidelines for both beginners and experienced astrophotographers * Includes simple projects which can be carried out with just a camera and tripod, as well as more advanced material - up to introductory research-level, for example, variable-star photometry

En djupgående genomgång av de fem kropparna i vårt solsystem som har bevis för underjordiska hav, samt andra kroppar som teoretiskt skulle kunna ha det.Exploring the Ocean Worlds of our Solar System - Författare: Bernard Henin In the last 25 years, planetary science experienced a revolution, as vast oceans of liquid water have been discovered within the heart of the icy moons of our Solar System. These subsurface oceans lie hidden under thick layers of ice. We call them ocean worlds. Some of these icy moons, such as Ganymede, may hold two to three times more liquid water than all the water present on Earth, while others, such as Enceladus and Europa, are thought by astrobiologists to be our best hope of finding extraterrestrial life. In this book, we will explore and compare a variety of Solar System ocean worlds, meeting in the process 22 of the most intriguing objects, from the giant asteroid Ceres to the enigmatic, distant Sedna. In doing so, we will also encounter the multiple spacecraft that brought back most of what we know of these worlds (Pioneers, Voyagers, Cassini-Huygens, etc.), as well as the latest scientific research on this new topic. We will also entertain the possibility of life on each of these ocean worlds by assessing their habitability, as ultimately, these ocean worlds might hold the key to answering the fundamental questions in life: How did life appear? Where do we come from? Is there life out there? With the contributions of leading planetary scientists from NASA, ESA, and other institutions, this book aims to be the go-to reference for anyone wanting to know more about this fascinating topic.

This book tells the story of two giants and a dwarf. The giants, Uranus and Neptune, are mostly huge balls of gas, and they make their home in the remotest reaches of the Solar System. The dwarf, Pluto, which can usually be found even farther out than the two giants, was always small, but up until a short while ago, it enjoyed the same status as the other planets, a full-fledged member of the Solar System. Today, Pluto has been re-classified as a "dwarf planet."Uranus, Neptune, and Pluto and How to Observe Them, Authors: Schmude, Jr., Richard In this clear and succinct overview of the current research on these remote Solar System objects, Richard Schmude, Jr., tells us what facts we do know about these faraway entities, what we are seeking to know, and also how to observe them for yourself, using commercially available telescopes. He also explains why Pluto was re-classified and what it means, exactly, to be a dwarf planet. Intrigued by these objects since boyhood, Schmude has compiled a loving tribute to them, if not making them warm and fuzzy, at least making them seem less remote and bringing them into our current frame of reference, giving them personality and revealing their worth in our understanding of the structure and nature of the Solar System in which we live.

Guides observers to the best nebulous objects in the night sky from any latitude, including the incorporation of numerous Southern Hemisphere objects Authored by a recipient of the "Master Observer Award" of the Astronomical League, who is extremely familiar with the instrumentation needed to view and image nebulae as well as having a deep understanding of their properties Contains many stunning pictures illustrating the beautiful and multi-colored nebulae of the Milky Way Observing Nebulae This book enables anyone with suitable instruments to undertake an examination of nebulae and see or photograph them in detail. Nebulae, ethereal clouds of gas and dust, are among the most beautiful objects to view in the night sky. These star-forming regions are a common target for observers and photographers. Griffiths describes many of the brightest and best nebulae and includes some challenges for the more experienced observer. Readers learn the many interesting astrophysical properties of these clouds, which are an important subject of study in astronomy and astrobiology. Non-mathematical in approach, the text is easily accessible to anyone with an interest in the subject. A special feature is the inclusion of an observational guide to 70 objects personally observed or imaged by the author. The guide also includes photographs of each object for ease of identification along with their celestial coordinates, magnitudes and other pertinent information. Observing Nebulae provides a ready resource to allow anyone with a little experience in astronomy, whether professional or amateur, to locate, identify and record the nebulae in our home galaxy. The author enables the observer to use a telescope and filters to the best advantage to see these celestial wonders, or to couple filters to a CCD camera or digital SLR camera in order to take quality images of celestial objects. By using these techniques it is even possible to make a valid contribution to professional investigations. And the views are unbeatable.

The uniquely beautiful light display of an aurora is the result of charged particles colliding with tenuous atmospheric oxygen and nitrogen, more than 60 miles above the Earth, when the magnetosphere is disturbed by changes in the solar wind.Aurora - Observing and Recording Nature's Spectacular Light Show, Authors: Bone, Neil Often - and incorrectly - regarded as being confined to high northern and southern latitudes, major auroral displays are visible from even the southern USA and the south of England, and occur perhaps twenty times in each eleven-year sunspot cycle. Major auroral storms always cause great interest and excitement in the media, and of course provide practical astronomers with the opportunity to study and image them. This book describes the aurora from the amateur observational viewpoint, discusses professional studies of auroral and geomagnetic phenomena to put amateur work in context, and explains how practical observers can go about observing and recording auroral displays.

En introduktion till solens historia.Solar History - An Introduction - Författare: Claudio Vita-Finzi Beyond the four centuries of sunspot observation and the five decades during which artificial satellites have monitored the Sun – that is to say for 99.99999% of the Sun's existence – our knowledge of solar history depends largely on analogy with kindred main sequence stars, on the outcome of various kinds of modelling, and on indirect measures of solar activity. They include the analysis of lunar rocks and meteorites for evidence of solar flares and other components of the solar cosmic-ray (SCR) flux, and the measurement of cosmogenic isotopes in wood, stratified ice and marine sediments to evaluate changes in the galactic cosmic-ray (GCR) flux and thus infer changes in the sheltering magnetic fields of the solar wind. In addition, shifts in the global atmospheric circulation which appear to result from cyclic fluctuations in solar irradiance have left their mark in river sediments and in the isotopic composition of cave deposits. In this volume the results these sources have already produced have been summarised, paying special attention to those that reflect processes in different parts of the Sun's interior and that display periodicities and trends which may enable us to forecast future large-scale environmental changes.

Every total solar eclipse sees cruise ships or coach convoys, and frequently both, conveying to thousands of observers the narrow umbral track, where they can witness this rare and beautiful astronomical event, weather permitting. But for each total solar eclipse you get just a few minutes (or seconds) to make the most of the spectacle, savor it visually, and record the event.Total Solar Eclipses and How to Observe Them, Authors: Mobberley, Martin * Describes the astronomy, science and physics of total solar eclipses, and the phenomena that can be observed only during a total eclipse. * Enables members of the growing community of eclipse chasers to ensure that they have with them all the right equipment to observe or image a total solar eclipse. * Describes what to expect during a total solar eclipse, in different conditions and in different locations. * Describes previous eclipse expeditions, including a look at the less serious side: eclipse expedition disasters. * Provides a checklist of where to go to see total solar eclipses for the next 15 years. Every total solar eclipse sees cruise ships or coach convoys, and frequently both, conveying to thousands of observers the narrow umbral track, where they can witness this rare and beautiful astronomical event, weather permitting. But for each total solar eclipse you get just a few minutes (or seconds) to make the most of the spectacle, savor it visually, and record the event. You have to get it right first time, which is where Total Solar Eclipses and How to Observe Them comes in. Here is all the information an eclipse chaser needs to ensure a trouble-free expedition. Martin Mobberley explains how to avoid equipment and set-up errors thousands of miles from home, advises on the right equipment to buy for observing and digital SLR imaging, and explains the crucial points to address when traveling abroad with astronomical equipment. The first part of the book contains a wealth of information about total solar eclipses themselves: how and why they happen, related physics of the Sun, the alignment geometries, and, of course, the astronomical features that can only be witnessed when our Moon precisely covers the solar disk.

A nontechnical, nonmathematical primer on amateur radio astronomy. Includes 4 new amateur projects, including bouncing a signal off the moon, detecting the aurora, ISS, and more. Offers expanded resources for the interested reader.

Denna mycket detaljerad och vattenresistent karta på månen är ett ovärderligt verktyg för alla amatörastronomer.Orion Moon map månkarta - språk: Engelska * Karten visar över 260 detaljer på månen, bland annat kratrar, dalar, lavaområden, bergskedjor och alla lyckade månlandningar av USA och Sovjet. * Vattenresistent och smutsresistent. * Storlek 64x28 cm öppnad eller 31,6x28 cm vikt ihop. * Kartan visar månen både i korrekt orientering och spegelvänd så att kartan passar till alla typer av teleskop eller kikare. Månens ljusa ansikte har inspirerat astronomer i århundraden. Eftersom månen är mycket närmare jorden än något annat föremål på natthimlen är utsikten över dess upplysta yta otroligt detaljerad när den observeras genom kikare eller ett teleskop. Spännande kratrar, klippiga berg och vidsträckta "hav" av forntida lavaflöden ger underbara mål för hobbyastronomer. Med den prisvärda Orion MoonMap 260 kan du enkelt identifiera, lokalisera och lära dig om de många intressanta funktionerna i jordens enda naturliga satellit. MoonMap identifierar över 260 av de mest populära månytan, inklusive kratrar, bergskedjor, dalar, sprickor, "hav" och mer. Varje fenomen kan refereras till i MoonMaps tabeller med dess officiella namn, storlek och en kort beskrivning. Förutom månlandskapsfunktioner är alla framgångsrika rymdskeppslandningsplatser från US Apollo, Surveyor och Ranger Probe-uppdrag samt sovjetiska Luna Probe-uppdrag också tydligt identifierade på kartan. Vi har designat Orion MoonMap 260 med mångsidighet i åtanke. Både en korrekt bild och en omvänd eller "spegelbild" -vy av månen ingår på kartan, så den kan användas när man observerar månen med enbart ögonen, kikare eller något refraktor-, spegel- eller Cassegrain-teleskop. Kartan är bekvämt laminerad för användning i nästan alla väder. Att använda MoonMap 260 är enkelt. Hitta bara referensnumret för det du vill identifiera på kartan och leta upp dess namn med hjälp av kartans numeriska index. Omvänt, om du vill hitta en specifik namngiven funktion med ditt teleskop eller kikare, använd kartans numeriska index för att hitta månfunktionens referensnummer och lokalisera numret och funktionen på kartan. För att underlätta användningen ordnas referensnumren ungefär från norr till söder (uppifrån och ner). Orion MoonMap 260 mäter 64 x 28 cm när den är helt utfälld och fälls ihop till 31,6 x 28 cm. Den tredubbla MoonMap 260 är plastlaminerad för långvarig hållbarhet samt skydd mot dagg, smuts och enstaka kaffespill. Oavsett om du är en erfaren amatörastronom eller en nybörjare som precis börjat utforska natthimlen, hjälper MoonMap 260 dig att göra varje månbelyst natt mer minnesvärd. Den är ett måste för varje "Luna" -tic!

Intressanta mysterier inom konst, historia, och literatur som kan undersökas och lösas med vetenskapliga metoder.Further Adventures Of The Celestial Sleuth - Författare: Donald W. Olson From the author of "Celestial Sleuth" (2014), yet more mysteries in art, history, and literature are solved by calculating phases of the Moon, determining the positions of the planets and stars, and identifying celestial objects in paintings. In addition to helping to crack difficult cases, these studies spark our imagination and provide a better understanding of the skies. Weather archives, vintage maps, tides, historical letters and diaries, military records and the assistance of experts in related fields help with this work. For each historical event influenced by astronomy, there is a different kind of mystery to be solved. How did the changing tides affect an army's battle plans? How did the phases of the moon affect how an artist painted a landscape? Follow these exciting investigations with a master "celestial sleuth" as he tracks down the truth and helps unravel mysteries as far back as the Middle Ages and as recent as the iconic 1945 photograph of a kiss in Times Square on VJ Day. Topics or "cases" pursued were chosen for their wide public recognition and intrigue and involve artists such as Vincent van Gogh and Claude Monet; historical events such as the campaigns of Braveheart in Scotland and battles in World War II and the Korean War; and literary authors such as Chaucer, Cervantes, Shakespeare, Byron, and Edgar Allan Poe.

Full-color maps show the constellations, with star types (spectral and physical) indicated by the colors used on the map. Extended objects such as galaxies and nebulae are shown with the approximate apparent size in the sky. With unmatched thoroughness and accessibility, this is a constellation atlas that makes the ideal companion to a night's telescope viewing, for novices and expert amateur astronomers alike. Easy to navigate and refer to, it is the key that unlocks the door to greater night sky exploration.

Mercury and Venus - known as the "inferior planets" because they are closer to the Sun than the Earth is - have always been regarded as difficult and even dangerous targets for amateur astronomers.Venus and Mercury, and How to Observe Them, Authors: Grego, Peter Recent advances in commercially-made instruments have, however, brought them within range of only moderately experienced observers, and certainly Mercury and Venus are by no means inferior in terms of visual delights, observing challenges...and mystery. Venus and Mercury and How to Observe Them offers a wealth of detailed practical information on every aspect of observing, from safely targeting the two planets, through visual observing, to sketching and electronic imaging. This is of course much more than a book about observing. We now know a lot more of the origin and evolution of Mercury and Venus, and Peter Grego describes the most recent theories of their probable formation, geology, and history. Not only does this include a lot about the surface of the planets, but also their internal structure, magnetic fields, and atmospheres. Peter Grego 2008, XIV, 266 p. 80 illus., 30 in color.
