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.

* Titel: The Universe Today * Författare: Carlos Martins * Språk: Engelska * Utgiven: 2020 * Format: Häftad * ISBN: 9783030496319 * Gives a gentle introduction to our current knowledge of the universe and how we came to our present view * Descriptive rather than mathematical, but includes maths separately for those seeking more detail * Author is an experienced teacher and popularizer in the field of astronomy and cosmology Starting out from humankind's earliest ideas about the cosmos, this book gives the reader a clear overview of our current understanding of the universe, including big bang theories and the formation of stars and galaxies, as well as addressing open questions. The author shows how our present view gradually developed from observations, and also how the outcome of ongoing research may still change this view. The book brings together concepts in physics and astronomy, including some history in both cases. The text is descriptive rather than technical: the goal is to present things rigorously and without oversimplification, by highlighting the crucial physical concepts. The only prerequisite is a qualitative knowledge of basic physics concepts at high-school level.

* Mizon, a well-known expert on light pollution, offers insider advice on the best dark sky sites * Includes photographs of some of the best astrophotographers * Encourages amateur astronomers to travel to protected observing locations with practical tips for how to observe once they are there Finding a Million-Star Hotel, author: Mizon, Bob Bob Mizon, one of the world's best known campaigners against the veil of light pollution that has taken away the starry sky from most of the world's population, takes readers to a hundred places in the UK and the USA where the wonders of the night sky might still be enjoyed in perfect or near-perfect night skies. Visiting small hotels and simple campsites, and savoring vast dark-sky reserves where the night sky is actively protected, The Million-Star Hotel celebrates the black skies of yesteryear – which may become a reality for more and more of us as modern technology reins in lighting and puts it only where needed. How can you prepare for your stay beneath the stars? What astronomy can you do during the daytime? What kind of equipment will you need? Questions such as these are answered, and if town dwellers return inspired – and, Bob hopes, also inspired to look with fresh eyes at their own local lighting – there is enough information here for them to equip themselves for some urban astronomy too.

* Enables Northern Hemisphere readers to quickly determine the next celestial event they can see with the naked eye. * Guides readers through eight years of the sky's rhythms via a month-by-month almanac and annual overviews with each year's best events. * Helps seasoned observers such as eclipse chasers plan travel for events. Celestial Delights, Authors: Reddy, Francis Celestial Delights is the essential "TV Guide" for the sky. Through extensive graphics integrated with an eight-year-long calendar of sky events, it provides a look at "don't miss" sky events, mostly for naked-eye and binocular observing. It is organized by ease of observation lunar phases and the brighter planets come first, with solar eclipses, the aurora, and comets coming later. This third edition also includes a hefty dose of sky lore, astronomical history, and clear overviews of current science. It provides a handy reference to upcoming naked-eye events, with information broken out in clear and simple diagrams and tables that are cross-referenced against a detailed almanac for each year covered. This book puts a variety of information all in one place, presents it in a friendly way that does not require prior in-depth astronomical knowledge, and provides the context and historical background for understanding events that astronomy software or web sites lack.

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.

Visualizes relevant physical information of stars and extended objects in an attractive and comprehensive way with different colors, symbol types, and sizes Covers the entire sky, both the Northern and Southern Hemisphere Contains position (and physical) information on enough stars to support star-hopping The Constellation Observing Atlas Designed for anyone who wishes to learn the constellations or observe the best and brightest deep sky objects and double stars, this book contains an alphabetical list of constellations complete with star maps, historical background, and highlights of deep sky objects. Each entry contains position and physical information on enough stars to support astronomers in star-hopping, swinging the telescope from star to star to star to arrive at a faint target. It provides a carefully selected list of accessible and rewarding deep sky objects. 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.

Nebulae are the places where the stars are born. For amateur astronomers, the many different kinds of nebulae vary from "easy" targets that can be seen with modest equipment under mediocre skies, to more obscure "challenging" objects that require experienced observers, more powerful telescopes and excellent observation conditions.Nebulae and How to Observe Them, Authors: Coe, Steven The concept of this book - and of the series - is to present an up-to-date detailed description and categorisation of nebulae, and then to instruct the reader in the best ways to successfully observe and record the large range of astronomical objects that fall under the general heading of "nebulae". Nebulae and How to Observe Them is a comprehensive mine of information for all levels of amateur observers, from the beginner to the experienced. The Astronomers Observing Guides are designed for practical amateur astronomers who not only want to observe, but want to know the details of exactly what they are looking at ASTRONOMERS OBSERVING GUIDES provide up-to-date information for amateur astronomers who want to know all about what it is they are observing. This is the basis of the first part of the book. The second part details observing techniques for practical astronomers, working with a range of different instruments. Steven Coe 1st Edition., 2007, X, 156 p. 128 illus., 11 in color.

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.

If you're wanting a challenge for your newly acquired telescope, or are interested in seeing what others have highlighted as some of the greatest sights in the night sky, this book will set you on the path of discovery.The Caldwell Objects and How to Observe Them There have been only a handful of famous deep sky "catalogs," including Charles Messier's, which was the first and remains the most famous. Messier was a comet hunter, and in the late 1700s he published a list of 109 objects in the sky that were not comets. In December 1995, Sky & Telescope published a list of deep sky objects sent to them by British amateur astronomer extraordinare, Sir Patrick Moore (officially, Sir Patrick Caldwell-Moore). It was a huge hit! Sir Patrick may be the most prolific authors of astronomy books for all time and has been presenting the BBC Sky at Night television series since April 1957. Moore's list contained 109 non-Messier objects that were Patrick's favorites, many of them visible only in the southern hemisphere. Accompanying the list of objects were long exposure black and white and color photographs of some of these objects. In this book Martin Mobberley, who has known Sir Patrick Moore for many years, describes these objects and tells how to locate them. He discusses the best ways to visually observe them and image them. He also tells a little of Moore's life and observing practices and how he made his choices for the "catalog." If you're wanting a challenge for your newly acquired telescope, or are interested in seeing what others have highlighted as some of the greatest sights in the night sky, this book will set you on the path of discovery.

A comprehensive solar observing guide for use at the telescope by amateur astronomers at all three levels: beginning, intermediate, and advanced. Users will find invaluable information for identifying features through photos, charts, diagrams in a logical, orderly fashion and then interpreting the observations.Observing the sun - A Pocket FieldGuide, Author: Jamey L. Jenkins Because the Sun is a dynamic celestial body in constant flux, astronomers rarely know for certain what awaits them at the eyepiece. All features of the Sun are transient and sometimes rather fleeting. Given the number of features and the complex life cycles of some solar features, it can be a challenging hobby, and this guide provides all of the guidance necessary to inform observers about the sights and events unfolding before their eyes on the most active and powerful member of our Solar System.

Examines not only Western monotheistic religions but also Eastern belief systems such as Buddhism, Jainism and Hinduism. Covers the history of the debate concerning extraterrestrial life and the current state of exoplanet research. Applies comparative theology to a neglected but soon to be vital question In the twenty-first century, the debate about life on other worlds is quickly changing from the realm of speculation to the domain of hard science. Within a few years, as a consequence of the rapid discovery by astronomers of planets around other stars, astronomers very likely will have discovered clear evidence of life beyond the Earth. Such a discovery of extraterrestrial life will change everything. Knowing the answer as to whether humanity has company in the universe will trigger one of the greatest intellectual revolutions in history, not the least of which will be a challenge for at least some terrestrial religions. Which religions will handle the discovery of extraterrestrial life with ease and which will struggle to assimilate this new knowledge about our place in the universe? Some religions as currently practiced appear to only be viable on Earth. Other religions could be practiced on distant worlds but nevertheless identify both Earth as a place and humankind as a species of singular spiritual religious importance, while some religions could be practiced equally well anywhere in the universe by any sentient beings. Weintraub guides readers on an invigorating tour of the world’s most widely practiced religions. It reveals what, if anything, each religion has to say about the possibility that extraterrestrial life exists and how, or if, a particular religion would work on other planets in distant parts of the universe.

Makes the area of astrochemistry accessible to amateur astronomers and the general educated publicThe Chemical Cosmos - A Guided Tour, Author: Steve Miller If you have ever wondered how we get from the awesome impersonality of the Big Bang universe to the point where living creatures can start to form, and evolve into beings like you, your friends and your family, wonder no more. Steve Miller provides us with a tour through the chemical evolution of the universe, from the formation of the first molecules all the way to the chemicals required for life to evolve. Using a simple Hydrogen molecule known as H-three-plus - as a guide, he takes us on a journey that starts with the birth of the first stars, and how, in dying, they pour their hearts out into enriching the universe in which we live. Our molecular guide makes its first appearance at the source of the Chemical Cosmos, at a time when only three elements and a total of 11 molecules existed. From those simple beginnings, H-three-plus guides us down river on the violent currents of exploding stars, through the streams of the Interstellar Medium, and into the delta where new stars and planets form. We are finally left on the shores of the sea of life. Along the way, we meet the key characters who have shaped our understanding of the chemistry of the universe, such as Cambridge physicist J.J. Thomson and the Chicago chemist Takeshi Oka. And we are given an insiders view of just how astronomers, making use of telescopes and Earth-orbiting satellites, have put together our modern view of the Chemical Cosmos.

This astronomy travel guide examines the many wonderful opportunities for experiencing the observing hobby. Amateur astronomy is often consigned to observing from home or from a local park, yet it can be much more.Astronomy Adventures and Vacations, author: Timothy Treadwell Tim Treadwell explores all the possibilities of astronomical and space-related activities that are available on day trips and longer vacations. These activities range from observatory visits and other simple ways to build an astronomy event into a holiday, to full blown specialized astronomy travel. Many trips give the opportunity to visit some of the world's famous attractions. On most vacations it can be a matter of just taking a day (or night) out of your schedule to fit in an astronomy event, but larger, dedicated pilgrimages are also possible. How to make the most of astronomy potential on a holiday, whether observing on the beach in Hawaii with the Telescope Guy or visiting Star City in Russia, is covered in detail. Go to a star party, explore the national parks or see the northern lights! There are a wide variety of activities for all budgets described in this book.
