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.

Provides a one-stop shop for the amateur variable star observer. Features chapters on binocular variable stars and photometric study of variable stars, topics that have not been addressed in most other amateur astronomy books. Uses non-mathematical language that is easily accessible to anyone with a general interest in astronomy. Provides basic and advanced information for an activity many amateur astronomers pursue once they have developed some skills in deep sky observing This book contains everything you need to know about variable stars -- stars whose brightness varies noticeably over time. The study of variable stars has been a particularly popular area of research for amateurs for many years; the material contained herein serves as both an introduction to amateur astronomers and a useful reference source for seasoned variable star observers.  With its thorough, non-mathematical descriptions of variable stars and tips for how to see them, this book enables novices and experts alike to set off into the field and observe a wide range of delightful sights. It strikes a balance between easily visible objects that can be seen in any telescope or binoculars, and variable stars that are a direct challenge to those with large aperture equipment or access to photometric tools and methods. After helping the observer differentiate between variable star types, the author goes on to explain the skills needed to operate a telescope and other equipment, as well as how to couple filters to a CCD camera or digital SLR camera in order to photometrically record these celestial objects. Further, the book includes an observational guide to 50 objects for study, with finder charts and data about light curves for ease of identification, along with the stars’ celestial coordinates, magnitudes, and other pertinent information.

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.

This book is a unique work satisfying the need for a modern, comprehensive review of all major aspects of galaxy observation.Galaxies and How to Observe Them, Authors: Steinicke, Wolfgang, Jakiel, Richard The book combines the physical background on the nature and data of galaxies, the relevant instrumentation and viewing techniques, and finally the targets and their individual appearance in telescopes of various apertures. A comprehensive sample of galaxies, including quasars, groups and clusters of galaxies is presented. This combination of theoretical knowledge and practical information guarantees successful observing sessions. Furthermore, the book is clearly structured with outstanding images and graphics.

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.

Jupiter is one of the most spectacular observing targets for amateur astronomers. There are various books about observing the planets, and several about Jupiter itself, but this is the only book to deal with the giant planet - its formation, structure, and incredible physics - as well as with the practical aspects of observation of the planet and its moons.Jupiter and how to observe it, Authors: McAnally, John W. The concept of the book - and of the series - is to present an up-to-date detailed physical and astrophysical description (part one) and then (part two) to consider how best to observe and image the giant planet. Jupiter and How to Observe It is a mine of information for all levels of amateur observers, from the beginning to the experienced, and will be fascinating reading for all practical amateur astronomers. 1st Edition., 2008, X, 218 p.
