Book Synopsis How Did the First Stars and Galaxies Form? by : Abraham Loeb
Download or read book How Did the First Stars and Galaxies Form? written by Abraham Loeb and published by Princeton University Press. This book was released on 2010-07-19 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: A concise introduction to cosmology and how light first emerged in the universe Though astrophysicists have developed a theoretical framework for understanding how the first stars and galaxies formed, only now are we able to begin testing those theories with actual observations of the very distant, early universe. We are entering a new and exciting era of discovery that will advance the frontiers of knowledge, and this book couldn't be more timely. It covers all the basic concepts in cosmology, drawing on insights from an astronomer who has pioneered much of this research over the past two decades. Abraham Loeb starts from first principles, tracing the theoretical foundations of cosmology and carefully explaining the physics behind them. Topics include the gravitational growth of perturbations in an expanding universe, the abundance and properties of dark matter halos and galaxies, reionization, the observational methods used to detect the earliest galaxies and probe the diffuse gas between them—and much more. Cosmology seeks to solve the fundamental mystery of our cosmic origins. This book offers a succinct and accessible primer at a time when breathtaking technological advances promise a wealth of new observational data on the first stars and galaxies. Provides a concise introduction to cosmology Covers all the basic concepts Gives an overview of the gravitational growth of perturbations in an expanding universe Explains the process of reionization Describes the observational methods used to detect the earliest galaxies

Download or read book Galaxies written by Francoise Combes and published by John Wiley & Sons. This book was released on 2021-03-05 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Galaxies are vast ensembles of stars, gas and dust, embedded in dark matter halos. They are the basic building blocks of the Universe, gathered in groups, clusters and super-clusters. They exist in many forms, either as spheroids or disks. Classifications, such as the Hubble sequence (based on mass concentration and gas fraction) and the colormagnitude diagram (which separates a blue cloud from a red sequence) help to understand their formation and evolution. Galaxies spend a large part of their lives in the blue cloud, forming stars as spiral or dwarf galaxies. Then, via a mechanism that is still unclear, they stop forming stars and quietly end in the red sequence, as spheroids. This transformation may be due to galaxy interactions, or because of the feedback of active nuclei, through the energy released by their central super-massive black holes. These mechanisms could explain the history of cosmic star formation, the rate of which was far greater in the first half of the UniverseÂs life. Galaxies delves into all of these surrounding subjects in six chapters written by dedicated, specialist astronomers and researchers in the field, from their numerical simulations to their evolutions.

Download or read book Stars and Galaxies written by Seeds and published by Thomson. This book was released on 2002-06 with total page 475 pages. Available in PDF, EPUB and Kindle. Book excerpt: Adapted from the newly revised FOUNDATIONS OF ASTRONOMY, 7th edition, STARS AND GALAXIES, 3rd edition contains the introductory and historical astronomy 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 3rd edition shows students their place in the universe - not just their location, but also their role as planet dwellers in an evolving universe. Fascinating and engaging, the book illustrates how science works, and how scientists depend on evidence to test hypotheses. Students will learn to focus on the scientific method through the strong central theme of "how we know what we know." Through a discussion of this interplay between evidence and hypothesis, Seeds provides not just a series of facts, but also a conceptual framework for understanding the logic of astronomical knowledge. The book vividly conveys the author's love of astronomy, 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, rather than simply memorizing facts. By crafting a story about astronomy, Seeds shows students how to ask questions of nature and therefore gradually puzzle out the beautiful secrets of the physical world. The book's use of mathematics is incorporated into the body of the text (as well as in separate sections for easy reference), but the arguments of the text do not depend on mathematical reasoning, allowing math-averse students to easily follow the story. The revision covers the history of astronomy, elementary physics concepts, stars and galaxies, cosmology, and the origin of life on earth and on other worlds.

Book Synopsis The Life Cycles of Stars by : Charles River

Book excerpt: *Includes pictures *Includes a bibliography for further reading When people look up into the night sky, the stars seem fixed and immutable, as unchanging as the darkness of space itself, but the truth is that stars are born, live and die in a never-ending cycle of creation and annihilation. These cycles stretch over such vast spans of time that, to short-lived humans, they seem to last forever. No one knows just how many stars there are, but their number is almost beyond comprehension. When people look up into the night sky, they can see further than they might guess: up to 19 quadrillion miles, the distance to Deneb in Cygnus, a star that is visible from most inhabited parts of Earth. In total, around five thousand stars are visible to the naked eye, though only around two thousand are visible at any one time from a particular place on Earth. All the visible stars are bigger and brighter than the Sun. Of course, there are many more known stars than those that can be seen with the naked eye. Astronomers estimate that in the Milky Way, there may be more than three hundred billion stars, and every other galaxy may have a similar number of stars. How many galaxies are there in the Universe? Again, no one is certain, but most astronomers agree that there must be many billions. Stars begin as vast clouds of dust and gas within galaxies and are known as nebulae. Due to Newton's Law of Global Attraction, the densest areas in these nebulae pull-in matter from the surrounding space. The more mass they gain, the more mass they attract. Over time, this accumulation can lead to the creation of a star. From that moment on, an eternal battle begins: gravity tends to contract the star while its growing inner pressure tends to expand it. Nebulae are stellar nurseries, the places where stars are created and an essential part of the life cycle of the Universe. Stars do not last forever. Over time they gradually lose energy and finally die. This process of the creation of new stars and the gradual death of existing stars is part of a vast, cosmic process of recycling that continues all the time. However, that raises the question of how the very first stars were formed and that in turn leads to questions about the origin of the Universe itself. However, the life cycle of stars also has a direct relationship to life here on Earth. Singer Joni Mitchell famously included the line "we are stardust" in her hit song "Woodstock." Surprisingly, it seems that she was absolutely right. In the beginning, the Universe comprised hydrogen, small quantities of helium, minuscule amounts of lithium and almost nothing else. Stars are the engines that provide the raw material from which life itself as well as stellar bodies are created. Each star is like a factory that uses nuclear fusion to convert hydrogen into helium and that in turn is used to create carbon, nitrogen, oxygen and many other elements. When a star dies, it ejects its outer layers, throwing these elements off as cosmic dust. The gravity of planets attracts and captures this dust which settles on the surface, introducing new elements. It is estimated that more than forty thousand tons of cosmic dust arrives on Earth every year and this process has continued as long as there has been a planet Earth. Some of the tiny pieces of dust (most are smaller than one-hundredth the width of a human hair) are very old indeed. Scientists have found what they call "original stardust" on meteorites and asteroids. Many of these have been drifting in space since before the Sun was created. The elements in this dust are the fundamental building-blocks of life and every living organism on Earth is created from elements that were originally produced in long-dead stars. It seems that humans and everything else on the planet really did begin as stardust.
