This is the story of radio astronomy, of how radio waves are generated by stars, supernova, quasars, colliding galaxies, and by the very beginnings of the universe itself. This revised book provides an update on the state of radio astronomy and those sections no longer regarded as cutting edge have been removed. With this book, aimed at a lay audience, you learn what astronomers are doing with those huge dishes. With each of these observatories, the scientists collect and analyze their data, "listening" to the radio signals from space, in order to learn what is out there, and perhaps even if someone else may be listening as well.
From the discovery of entirely new kinds of galaxies to a window into cosmic ‘prehistory’, Bothwell shows us the Universe as we’ve never seen it before – literally. Since the dawn of our species, people all over the world have gazed in awe at the night sky. But for all the beauty and wonder of the stars, when we look with just our eyes we are seeing and appreciating only a tiny fraction of the Universe. What does the cosmos have in store for us beyond the phenomena we can see, from black holes to supernovas? How different does the invisible Universe look from the home we thought we knew? Dr Matt Bothwell takes us on a journey through the full spectrum of light and beyond, revealing what we have learned about the mysteries of the Universe. This book is a guide to the ninety-nine per cent of cosmic reality we can’t see – the Universe that is hidden, right in front of our eyes. It is also the endpoint of a scientific detective story thousands of years in the telling. It is a tour through our Invisible Universe.
Nasser offers a guide for Christians who want to learn to hear and see God in their everyday lives, focusing on hyow to listen and where to look.
Please note: This is a companion version & not the original book. Sample Book Insights: #1 Light is the tool through which we understand our cosmos. Everything we know about our place in the Universe is based on light. Light is a wonder that we are so familiar with in our everyday lives that we can easily overlook how strange it really is. #2 The idea that light is produced by sources and then enters our eyes is a modern one, and was not accepted by many philosophers throughout history. The ancient Greek philosopher Democritus believed that all matter is made of tiny ‘atoms’ that are constantly expelling ghostly images called ‘eidola’ that fly through the air until they enter our eyes. #3 The Scientific Revolution, which took place hundreds of years later, was made possible by the advances in science made by the Arab astronomer Hasan Ibn al-Haytham. His ideas about light, which were new and revolutionary, allowed us to see the Universe in a new way. #4 The speed of light was measured first by astronomy, where distances of millions of kilometres are common. The first good estimate of the speed of light came from Galileo, who saw the moons of Jupiter orbiting around their parent planet.
Presents an overview of the Hubble Space Telescope, describing its initial launch in 1990 and impact on our understanding of the universe, along with some of its latest images of galaxies, stars, planets, and nebulas.
This is a work of fiction. A novel based on a foundation of certain firm probabilities. The reader never knows if he has reached the end. He is unwilling to leave the Kingdom; he is unwilling to forget Princess Rajeswary; he does not want to leave the company of the ascetic Vishnushatry; he is willing to remain spellbound by the lectures of Professor Arjun and Catherine; he wants to visit the North Woods to have a glimpse of the majestic Promi Sierra; he wants to see how Suryawarma’s sword blazes. He wants to return again and again to the chapters that are so adorable and so realistic. He is caged within the pages… No, this is not a novel. It is a visit to an extraordinarily enchanting place. The stories are intertwined cohesively to present the story of a small civilization, and there is a shade of mystery! The kingdom of Promipur is a wealthy and advanced kingdom—advanced in terms of human progression in the absolute sense. At the conclusion, the reader is unwilling to keep the book down, wishing only that what happens at the end ought not to have happened.
Harry Oldfield is an extraordinary scientist and healer who has spent the last 20 years proving that mystical emanations such as visions and psychic manifestations have a basis in science. A pioneer of the Kirlian photography, Oldfield has developed a photographic scanning method that can diagnose illness and photograph the chakras. He has also discovered an Electro-Scanning Method (ESM) which can ascertain a full medical history from a fully clothed patient in two minutes and founded a school teaching students his Electro-Crystal Therapy techniques.
An astrophysicist recounts how her team of researchers surfed the cosmos to map our local universe—and discovered the Laniakea supercluster, home of the Milky Way. You are here: on Earth, which is part of the solar system, which is in the Milky Way galaxy, which itself is within the extragalactic supercluster Laniakea. And how can we pinpoint our location so precisely? For 20 years, astrophysicist Hélène Courtois surfed the cosmos with international teams of researchers, working to map our local universe. In this book, Courtois describes this quest and the discovery of our home supercluster. Courtois explains that Laniakea (which means “immense heaven” in Hawaiian) is the largest galaxy structure known to which we belong; it is huge, almost too large to comprehend—about 500 million light-years in diameter. It contains about 100,000 large galaxies like our own, and a million smaller ones. Writing accessibly for nonspecialists, Courtois describes the visualization and analysis that allowed her team to map such large structures of the universe. She highlights the work of individual researchers, including portraits of several exceptional women astrophysicists—presenting another side of astronomy. Key ideas are highlighted in text insets; illustrations accompany the main text. The French edition of this book was named the Best Astronomy Book of 2017 by the astronomy magazine Ciel et espace. For this MIT Press English-language edition, Courtois has added descriptions of discoveries made after Laniakea: the cosmic velocity web and the Dipole and Cold Spot repellers. An engaging account of one of the most important discoveries in astrophysics in recent years, her story is a tribute to teamwork and international collaboration.
