Some stars, however, go out in spectacular fashion as supernovas, exploding
into vast fields of debris that eventually contribute to the creation of new stars. In
the vast scheme of the universe, the Sun is a pretty average star. It is estimated to

Most avid sky gazers wait until nightfall to catch a glimpse of the stars that are scattered across the heavens. The fact of the matter is that one needs only to feel the Suns rays in order to experience the presence of a star. The Sun is an ordinary star, a ball of hot gas much like millions of others in the universe, but as the center of the solar system, it is critical to the survival of all life forms on Earth. This comprehensive volume examines the nature of the Sun and details the properties and types of various stars, as well as the greater galaxies of which they are a part.
The earth is one of nine planets that circle around the sun . It also includes stars .
The sun is a star . Stars are much larger than planets . The sun is one of about
100 billion stars that make up our Milky Way galaxy . Galaxies stretch out over ...

Discusses discoveries and theories concerning planets, stars, and galaxies.
Astronomy gives us some comprehension of the workings of stars, galaxies, and
planets, but its greatest value lies in what it teaches us about ourselves. Now that
we have surveyed astronomical knowledge, we can better understand our own ...

Adapted from the newly revised FOUNDATIONS OF ASTRONOMY, Sixth Edition, STARS AND GALAXIES, Second Edition contains the introductory and historical chapters from FOUNDATIONS, as well as all of the chapters on stars, galaxies, cosmology, and the chapter on extraterrestrial life. This newly revised and updated Second Edition shows students their place in the universe -- not just their location, but also their role as planet dwellers in an evolving universe. In a clear and conversational writing style, Seeds shows students how science works, and how scientists depend on evidence to test hypotheses. Through a discussion of this interplay between evidence and hypothesis, the book provides not just a series of facts, but also a conceptual framework for understanding the logic of astronomical knowledge. Fascinating and vivid, the book conveys the author's love of the subject, shows students how the universe can be described by a small set of physical laws, and illustrates how they can comprehend their place in the universe by understanding these laws, and not through memorization of facts. The book's use of mathematics is incorporated into the body of the text, but the arguments of the text do not depend on mathematical reasoning, allowing math-averse students to easily follow the story.

Our workshop was divided in two important sections: (1) Sun and Heliosphere; (2) Stars and galaxies. The first section treated solar magnetic structures such as active regions, flares and CMEs, prominences and coronal streamers. Both observational and models works were presented. Flows, boundaries and interfaces were approached in numerical simulations. The second section of the workshop was devoted to stellar studies, extragalactic astronomy and especially cosmology.
