The concept of summerschools and workshops at the Kanzelh· ohe · Solar Observatory, Karn · · ten, Austria, devotedtoup-to-datetopicsinsolarphysics has been proven to be extremely successful, and thus in August/September 2003 the third combined summerschool and workshop was held there. This book contains the proceedings of the Summerschool and Wo- shop "Solar Magnetic Phenomena" held from 25 August to 5 September 2003 at the Solar Observatory Kanzelh· ohe, · which belongs to the Institute for Geophysics, Astrophysics and Meteorology of the University of Graz, Austria. The book contains the contributions from six invited lecturers. They give an overview on the following topics: observations of the pho- sphere and chromosphere, solar?are observations and theory, coronal mass ejections and the relevance of magnetic helicity, high-energy radiation from the Sun, the physics of solar prominences and highlights from the SOHO mission. The lectures contain about 25 to 30 pages each and provide a valuableintroduction to the topics mentioned above. The comprehensive lists ofreferences at theendof each contribution enablethe interested reader to go into more detail. The second part of the book contains contributed papers. These - pers were presented anddiscussed in theworkshop sessions during the afternoons. The sessions stimulated intensive discussions between the p- ticipants and lecturers

Recording the proceedings of the IAU XXVI General Assembly, this volume of the IAU Highlights of Astronomy covers virtually all aspects of modern astrophysics as discussed by 2400 participants from 73 countries. Notably, the common aspects of astrophysical phenomena known to exist in widely differing interstellar environments is thoroughly examined, providing fertile cross correlation from one specialisation to another. This text highlights the importance of the triennial IAU General Assemblies in bringing together the work of observers and theoreticians in widely different fields, but working towards a common goal: understanding the physics of the Universe. Together with the Proceedings of the IAU Symposia 235-240, this volume examines all of the astrophysics presented at the General Assembly.

From planetary movements and the exploration of our solar system to black holes and dark matter, this comprehensive reference simplifies all aspects of astronomy with an approachable question-and-answer format. With chapters broken into various astronomical studies—including the universe, galaxies, planets, and space exploration—this fully updated resource is an ideal companion for students, teachers, and amateur astronomers, answering more than 1,00 questions, such as Is the universe infinite? What would happen to you if you fell onto a black hole? What are the basic concepts of Einstein's special theory of relativity? and Who was the first person in space?

It’s a good story: we are made of matter like that we also find in the stars. Essential to our planet’s existence, the Sun—our nearest star––is also the most fascinating object humans have ever adored, literally the difference between day and night. But getting beyond these basic perceptions requires scientific understanding. What, for instance, is the sun made of? Why does it burn so brightly? How long will it last? This book not only answers these questions but also tells the story of how we came to know—not merely behold—the grandest entity in our sky. Leon Golub and Jay M. Pasachoff offer an engaging and informative account of solar science and its history, drawing on centuries of study by solar astronomers who have looked to the Sun not only to learn about our own solar system but also about what lies in the distant wilderness of faintly glimmering stars. They skim along the surface of the Sun, which is decorated with sunspots, discussing these fascinating magnetic aberrations and the roughly eleven-year cycles they abide. They follow seismic waves into the interior of the Sun and its unending nuclear fusion. They show us what is unveiled in solar eclipses and what new views and knowledge our space exploration has afforded us. They brave solar weather, and they trace the arcs of radiation and particles whose effects we can see on earth in phenomena such as the northern and southern lights. Glowing with a wide assortment of astonishing images, this beautifully illustrated guide will delight everyone, from those who know what a coronagraph is to those who simply like to step out on a bright day, close their eyes, and feel the Sun’s warmth upon their skin.
