The latest discoveries about our universe to keep readers updated on the latest developments in space.

This book looks at answers to the biggest questions in astronomy – the questions of how the planets, stars, galaxies and the universe were formed. Over the last decade, a revolution in observational astronomy has produced possible answers to three of these questions. This book describes this revolution. The one question for which we still do not have an answer is the question of the origin of the universe. In the final chapter, the author looks at the connection between science and philosophy and shows how new scientific results have laid the groundwork for the first serious scientific studies of the origin of the universe.

This book provides a comprehensive, self-contained introduction to one of the most exciting frontiers in astrophysics today: the quest to understand how the oldest and most distant galaxies in our universe first formed. Until now, most research on this question has been theoretical, but the next few years will bring about a new generation of large telescopes that promise to supply a flood of data about the infant universe during its first billion years after the big bang. This book bridges the gap between theory and observation. It is an invaluable reference for students and researchers on early galaxies. The First Galaxies in the Universe starts from basic physical principles before moving on to more advanced material. Topics include the gravitational growth of structure, the intergalactic medium, the formation and evolution of the first stars and black holes, feedback and galaxy evolution, reionization, 21-cm cosmology, and more. Provides a comprehensive introduction to this exciting frontier in astrophysics Begins from first principles Covers advanced topics such as the first stars and 21-cm cosmology Prepares students for research using the next generation of large telescopes Discusses many open questions to be explored in the coming decade

Learn about the newest discoveries in the Milky Way and beyond in this updated edition from nonfiction master Gail Gibbons. Planet Earth is in the Milky Way Galaxy, the cloudy band of light that stretches clear across the night sky. How many galaxies are there in the universe? For years astronomers thought that the Milky Way was the universe. Now we know that there are billions of them. Gail Gibbons takes the reader on a journey light-years away. This updated edition vetted by an expert introduces young readers to our own galaxy the Milky Way and beyond. Learn how ancient people invented the telescope and began studying the Milky Way to the modern technology astronomers use to study other galaxies. Gail Gibbon’s easy-to-read text and clearly labeled illustrations welcomes young readers to learn how telescopes work, about the different types of galaxies, how many galaxies we know of today, and more.

"This captivating book explores the stars and planets of outer space by presenting them through lush illustrations and photography that incorporate cross-sections, cutaway-views, and magnifications. These images are paired with an accessible text to provide a well-balanced introduction to outer space."

There is more to outer space than what we can see in the night sky. Explore it all with Amazing World Stars & Planets and be a real space traveler. How is a star born? Why does it die? What is the difference between a star cluster and a planetary nebula? Discover the answers to these questions and more in Amazing World: Stars and Planets! This exciting exploration is a door to the infinite realm beyond the pale blue dot we call home. From stellar nurseries, to glowing green clouds, to spiral galaxies, find out about the dramatic lives of these explosive players in our universe. This is the perfect introduction to the great celestial bodies of outer space for science lovers and their children.

Amazing World Stars & Planets also includes a collection of glow-in-the-dark stickers to put on notebooks, folders, bedroom ceilings, anywhere!

This volume of Astrophysical Data deals with Planets and Stars; a second volume, Part II, will give data for Galaxies and the Universe. They both pro vide basic data for use by all scientists, from the amateur astronomer to the professional astrophysicist. In this first volume, we not only provide physical parameters of planets, stars and their environment, but we also provide the celestial coordinates required to observe them. Here we use c.g.s. units, for they are the most commonly used in astron omy and astrophysics; but our volume begins with astronomical and physical constants and the conversion factors needed for other units. The next section concerns the planets and their satellites; it singles out the Earth and Moon for special treatment. Spacecraft rendezvous with the planets and satellites have led to improved values for their atmospheric compositions, orbital parameters, magnetic fields, masses, radii, rotation periods, and surface pressures and temperatures. This section also contains data for the asteroids, comets and their debris. We then discuss everyday stars, beginning with the Sun, and continuing with basic stellar data, the brightest stars and nearby stars. Special categories of stars, such as the Wolf-Rayet stars, magnetic stars, flare stars, and RS CVn binary stars, are included.

Comprehensive introductory survey: the sun, solar system, stars, galaxies, universe, cosmology; quasars, radio stars, etc. 24pp. of photographs.
