Book Synopsis Cosmic Pinwheels: Spiral Galaxies And The Universe by : Ronald J Buta
Download or read book Cosmic Pinwheels: Spiral Galaxies And The Universe written by Ronald J Buta and published by World Scientific. This book was released on 2020-10-29 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'It is strongly biased towards the author's speciality of galaxy morphology, and particularly to bars and rings. To be fair, these are often given fairly short shrift in other textbooks, so this is a useful source of detail on such topics from an expert. In addition, references to original technical papers are given throughout which makes the book a handy introduction to the literature (which students may well find useful).'The Observatory MagazineThe main goal of the book is to introduce the reader to the world of spiral galaxies, how spirals were discovered, what they represent from a physical point of view, and what people have learned about the universe and the nature of galaxies in general from the study of spirals. Topics include early discoveries of nebulae, the island universe concept, the structure of spirals as seen both visually with telescopes and in images obtained with different filters, the role of spirals in the discovery of interstellar dust and dark matter, the different kinds of spiral galaxies and the importance of bars and rings, how different non-spiral galaxy types such as elliptical galaxies and S0 galaxies connect to spirals, and how spirals have contributed to our understanding of star formation and evolution, galaxy formation and evolution, the cosmological distance scale, and the universal expansion. The Milky Way as a spiral galaxy is also discussed.The book is profusely illustrated and not only a discourse on the spirals, but is also a personal reminiscence based on the author's studies of spiral galaxies over the past 45 years.

Download or read book The Cosmos written by Craig G. Fraser and published by Bloomsbury Publishing USA. This book was released on 2006-07-30 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: Everyone knows that the universe is extremely old and extremely large. But how did scientists determine just how old and how large? How do astronomers know that there are upwards of 100 billion galaxies in the universe if the nearest one is over 40,000 light-years away? How do we know what the stars are made of? The answer is that our current knowledge of the universe has arisen from the work and ideas of scientists and philosophers over hundreds of years. While it's only been during the last several decades that scientists have had the technology and theories to really understand how the universe works, humans have thought about such issues for millennia. And the scientists who today are attempting to understand the most complex issues of the universe build upon the work and thought of the thinkers of the last hundreds of years. The Cosmos: A Historical Perspective provides an accessible introduction to the many ways humans have conceived of the universe throughout history and what ideas have led to our current understanding of the cosmos. The book examines: the Scientific Revolution and the new ideas of the Earth's place in the cosmos; the importance of nineteenth-century physics and chemistry in determining the compositions of stars; Einstein's Theory of Relativity and how it altered how scientists thought about gravity; and new, cutting-edge science that may alter, yet again, our conceptions of the cosmos, such as the inflationary universe and the possibility of dark energy. Jargon and mathematics is kept to a minimum, and the volume includes an annotated bibliography and a timeline. The Cosmos is an ideal introduction for students studying space science and the history and nature of the scientific understanding of the universe.

Book Synopsis Astronomy and Astrophysics - Volume I by : Oddbjørn Engvold Bozena Czerny, John Lattanzio and Rolf Stabell
Download or read book Astronomy and Astrophysics - Volume I written by Oddbjørn Engvold Bozena Czerny, John Lattanzio and Rolf Stabell and published by EOLSS Publications. This book was released on 2012-11-30 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: Astronomy is the science of everything – with the exception of the Earth and everything on it and inside. Astronomy has a rich heritage dating back to the myths and legends of antiquity and the course of civilization has been greatly affected by mankind’s interpretation of what they saw in the starry sky and experienced through seasonal changes associated with the Sun and Moon. Early astronomy is associated with the definition of calendars which were needed to predict the dates of such as religious festivals and the numbers of months. A gradual shift of emphasis from astronomy to its sister, astrophysics, which took place through the 19th century, is generally attributed to the measurement of reliable stellar distances and the development of spectroscopy as a tool for understanding the physical nature of stars. Many paradigms in astronomy and its many subfields are continuously being shaken. New insights in the intricacy and elegance of the cosmos are steadily being obtained. Every few decennia, our concepts of the Universe are challenged and substantially modified. The reasons for this are the continuous development of new observing techniques and instruments for observatories both ground-based and in space, in addition to considerable progress in mathematics and physics, including computational ability. Our Universe harbors numerous phenomena and processes representing conditions that cannot be duplicated in terrestrial laboratories. Astronomy therefore frequently leads to fundamentally new insight and knowledge far beyond astronomy itself. Last but not least, it represents a first inspiring introduction to natural science, especially among young people, which is an extra motivation to many scientists to contribute to the Astronomy and Astrophysics Theme of this Encyclopedia. The book on Astronomy and Astrophysics with contributions from distinguished experts in the field, represents a first inspiring introduction to natural science, especially among young people, which is an extra motivation to many scientists to contribute to the Astronomy and Astrophysics Theme of this Encyclopedia. The first chapter which treats the development of astronomy and astrophysics in a historical perspective is followed by an account of the impact of astronomy on human culture and civilization. Observational astronomy is facing a number of environmental challenges. The nature and complexity of these and how the associated problems are met and overcome are described in the third article. Various aspects of our solar system are covered by authoritative articles on the Sun, planets including their satellites and smaller bodies, plus a review of the laws of motions and orbits of celestial bodies. The detection and studies of exo-solar planetary systems is rapidly developing field in astronomy which is treated in a separate chapter. Then follow fascinating up-to-date overviews on stars describing their formation, structure and life cycles. Stars are the building blocks of larger cosmic entities leading to the enigmatic galaxies composed of billions of stars, and gradually to clusters of galaxies. The final chapters cover the origin and evolution of galaxies and the large-scale structure of the Universe, including dark matter and dark energy which are among the most fascinating problems of physics today. These two volumes are aimed at the following five major target audiences: University and College students Educators, Professional practitioners, Research personnel and Policy analysts, managers, and decision makers and NGOs.
Book Synopsis Astronomy with Schmidt-Type Telescopes by : M. Capaccioli
Download or read book Astronomy with Schmidt-Type Telescopes written by M. Capaccioli and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 609 pages. Available in PDF, EPUB and Kindle. Book excerpt: The idea of holding a colloquium on Schmidt telescopes (techniques and science) originated from the observation that, in the last ten years and in spite of the remarkable developments and achievements in this field of astronomical research, there had been no specific opportunity for the experts to meet together, make the point on the state of the art, discuss and coordinate future plans. Therefore, Prof. L. Rosino, one of the pioneers in the use of wide-field telescopes, driven also by the wish of honouring the over four decades of activity of the Asiago Observatory, proposed to the Executive Committee of the International Astronomical Union to sponsor a colloquium on 'Astronomy with Schmidt type telescopes I to be held at Asiago at the end of the summer of 1983. Details about the composition of the Scientific Organizing Committee and the sponsoring organizations are given in Prof. Rosino's 'Welcome to the Participants • The granting of this proposal was the beginning of a ' number of headaches tor the members of the Local Organizing Committee, R. Barbon, F. Ciatti, P. Rafanelli and myself. If, organlzationwise, the colloquium was successful, this is truly due to the generous efforts of my colleagues of the SOC and to the efficient organization of the Linta Park, the hotel hosting the meeting.
Book Synopsis The Brightest Stars by : C. de Jager
Download or read book The Brightest Stars written by C. de Jager and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: No part of the Hertzsprung-Russell diagram shows a more pronounced diversity of stellar types than the upper part, which contains the most luminous stars. Can one visualize a larger difference than between a luminous, young and extremely hot Of star, and a cool, evolved pulsating giant of the Mira type, or an S-type supergiant, or - again at the other side of the diagram - the compact nucleus of a planetary nebula? But there is order and unity in this apparent disorder! Virtually all types of bright stars are evolutionally related, in one way or the other. Evolution links bright stars. In many cases the evolution is speeded up by, or at least intimately related to various signs of stellar instability. Bright stars lose mass, either continuously or in dramatic sudden events, they vibrate or pulsate - and with these tenuous, gigantic objects this often happens in a most bizarre fashion. Sometimes the evolution goes so fast that fundamental changes are observable in the time span of a human's life - several of such cases have now been identified.

Book Synopsis Cataclysmic Variables by : A. Bianchini
Download or read book Cataclysmic Variables written by A. Bianchini and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 529 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cataclysmic Variables (CVs) are well furnished laboratories in which one can investigate a number of important physical processes. These processes include: thermonuclear reactions, nebular physics, winds, mass accretion phenomena on compact objects, magnetohydrodynamics, plasmas, thermal and non thermal radiative processes, relativistic phenomena, dust forma tion, etc . . In the recent year the most exciting development in our opinion was that the small, cold and invisible secondary components of CV s were found to be the prime motors for the evolution of close binary systems, disclosing new scenarios for research. All branches of astronomy and as trophysics often take advantage of the new ideas brought by the study of CVs. It is for this reason, we believe, that meetings on CVs are important for most of the astronomical community. The idea of a Congress on CVs in Padova has been fluttering in the air for a few years. After all - we thought - a large part of the scientific heritage of Padova and Asiago Observatories is represented by the study of variable stars and, in particular, of CV s, as Prof. L. Rosino reminded us at the very beginning of the Congress. We finally chose Abano Terme as the site of the Conference, not merely because Abano is one of the most famous centers in Europe for mud therapy, and astronomers easily suffer from rheumatism, but also because we knew that a very hearty welcome from the Abano Municipality and touristic associations awaited us.
Book Synopsis Edwin Hubble, The Discoverer of the Big Bang Universe by : Alexander S. Sharov

This book was released on 1993-10-14 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the first complete account of the scientific life and work of Edwin Hubble, whose discoveries firmly established the United States as the leading nation in observational astronomy. One of the outstanding astronomers of the twentieth century, Hubble discovered the expansion of the Universe. He opened the world of galaxies for science when he showed that spiral nebulae beyond the Milky Way are galaxies extending to the limits of the Universe, and participating in a general expansion of the cosmos. The exploding Universe of Hubble, now termed the Big Bang, determined the origin of the elements, of galaxies and of the stars. The second part of the book describes the fundamental discoveries on the nature of the Universe made subsequently, and thus sets his achievements in context. Written by two prominent astronomers who have built on Hubble's work, this book is a classic of science, setting out the thrilling story of the exploding Universe.
