Book excerpt: Living with the Stars tells the fascinating story of what truly makes the human body. The body that is with us all our lives is always changing. We are quite literally not who we were years, weeks, or even days ago: our cells die and are replaced by new ones at an astonishing pace. The entire body continually rebuilds itself, time and again, using the food and water that flow through us as fuel and as construction material. What persists over time is not fixed but merely a pattern in flux. We rebuild using elements captured from our surroundings, and are thereby connected to animals and plants around us, and to the bacteria within us that help digest them, and to geological processes such as continental drift and volcanism here on Earth. We are also intimately linked to the Sun's nuclear furnace and to the solar wind, to collisions with asteroids and to the cycles of the birth of stars and their deaths in cataclysmic supernovae, and ultimately to the beginning of the universe. Our bodies are made of the burned out embers of stars that were released into the galaxy in massive explosions billions of years ago, mixed with atoms that formed only recently as ultrafast rays slammed into Earth's atmosphere. All of that is not just remote history but part of us now: our human body is inseparable from nature all around us and intertwined with the history of the universe.

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.

Download or read book Neutron Stars Black Holes and Gravitational Waves written by James J Kolata and published by . This book was released on 2019-04-10 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Albert Einstein's General Theory of Relativity, published in 1915, made a remarkable prediction: gravitational radiation. Just like light (electromagnetic radiation), gravity could travel through space as a wave and affect any objects it encounters by alternately compressing and expanding them. However, there was a problem. The force of gravity is around a trillion, trillion, trillion times weaker than electromagnetism so the calculated compressions and expansions were incredibly small, even for gravity waves resulting from a catastrophic astrophysical event such as a supernova explosion in our own galaxy. Discouraged by this result, physicists and astronomers didn't even try to detect these tiny, tiny effects for over 50 years. Then, in the late 1960's and early 1970's, two events occurred which started the hunt for gravity waves in earnest. The first was a report of direct detection of gravity waves thousands of times stronger than even the most optimistic calculation. Though ultimately proved wrong, this result started scientists thinking about what instrumentation might be necessary to detect these waves. The second was an actual, though indirect, detection of gravitational radiation due to the effects it had on the period of rotation of two "neutron stars" orbiting each other. In this case, the observations were in exact accord with predictions from Einstein's theory, which confirmed that a direct search might ultimately be successful. Nevertheless, it took another 40 years of development of successively more sensitive detectors before the first real direct effects were observed in 2015, 100 years after gravitational waves were first predicted. This is the story of that hunt, and the insight it is producing into an array of topics in modern science, from the creation of the chemical elements to insights into the properties of gravity itself.

Available in PDF, EPUB and Kindle. Book excerpt: It is the stars, The stars above us, govern our conditions. William Shakespeare, King Lear A Few Words about What, Why and How The structure of the stars in general, and the Sun in particular, has been the subject of extensivescienti?cresearchanddebateforoveracentury.Thediscoveryofquantum theoryduringthe?rsthalfofthenineteenthcenturyprovidedmuchofthetheoretical background needed to understand the making of the stars and how they live off their energysource. Progress in the theoryof stellar structurewasmade through extensive discussions and controversies between the giants of the ?elds, as well as brilliant discoveries by astronomers. In this book, we shall carefully expose the building of the theory of stellar structure and evolution, and explain how our understanding of the stars has emerged from this background of incessant debate. About hundred years were required for astrophysics to answer the crucial ques tions: What is the energy source of the stars? How are the stars made? How do they evolve and eventually die? The answers to these questions have profound im plications for astrophysics, physics, and biology, and the question of how we our selves come to be here. While we already possess many of the answers, the theory of stellar structure is far from being complete, and there are many open questions, for example, concerning the mechanisms which trigger giant supernova explosions. Many internal hydrodynamic processes remain a mystery. Yet some global pictures can indeed be outlined, and this is what we shall attempt to do here.

Download or read book Origen and the Life of the Stars written by Alan Scott and published by Oxford University Press on Demand. This book was released on 1994 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: It was widely assumed by intellectuals from antiquity to the Middle Ages that the beauty and regularity of the heavens was a sign of their superior life. Through this belief the stars gained an important position in Greek religion, and speculations on their nature figured prominently indiscussions of human psychology and eschatology. In the third century AD the influential Christian theologian Origen included Hellenistic theories on the life and nature of the stars in his cosmology. This marked an interesting episode in the history of the idea, but it also had important implications for early Christian theology. Although he wascondemned as heretical for these (and other) speculations, he was successful in incorporating traditional philosophical theories about the stars into a biblical theology.
