The International Astronomical Union formalized the naming of meteor showers in 2006. Each newly discovered shower now is assigned a unique and officially recognized name, number, and 3-letter code. Close to a thousand possible meteor showers have since been reported, over a hundred in the cause of writing this book. Atlas of Earth's Meteor Showers takes stock of all reported detections by going back to the combined video and radar data in hand at the end of 2021, in order to weed out duplicates and false detections. Maps were created that show the direction of motion of meteors (their radiant) during 5-day and 10-day intervals throughout the year. All 500+ showers recognized are briefly described from their radiant, speed, and orbital elements, and the meteoroid mass distribution index was calculated. Physical properties of the meteoroids were derived from their beginning, peak and end height, from their deceleration in Earth's atmosphere, and from spectroscopic information. Candidate parent bodies are mentioned and the age of the stream was calculated from the dispersions in orbital elements and from the meteor magnitude distribution index. A brief history is given of the shower's discovery, of when features were first recognized, and of results from dynamical modeling, all with references to the literature. - Presents approximately 400 detailed meteor shower maps that show what showers are active on a given night for visual, video, and radar observers - Provides thorough descriptions of each shower that can be used in planetary astronomy and for meteor observing sessions, the discovery of new showers, and planetary defense - Highlights periodic, unusual showers that may be expected on a given night based on past occurrences that are important to satellite hazard avoidance and meteor storm chasing
Meteor Showers and their Parent Comets is a unique handbook for astronomers interested in observing meteor storms and outbursts. Spectacular displays of 'shooting stars' are created when the Earth's orbit crosses a meteoroid stream, as each meteoroid causes a bright light when it enters our atmosphere at high speed. Jenniskens, an active meteor storm chaser, explains how meteoroid streams originate from the decay of meteoroids, comets and asteroids, and how they cause meteor showers on Earth. He includes the findings of recent space missions to comets and asteroids, the risk of meteor impacts on Earth, and how meteor showers may have seeded the Earth with ingredients that made life possible. All known meteor showers are identified, accompanied by fascinating details on the most important showers and their parent comets. The book predicts when exceptional meteor showers will occur over the next fifty years, making it a valuable resource for both amateur and professional astronomers.
In 2014, Rosetta became the first mission to orbit a comet and to deploy a lander onto its surface. This is the story of ESA’s pioneering comet explorer, following the mission from its initial inception to its historic touchdown. Read along as the Rosetta orbiter and its lander, Philae, evolve over the years, overcoming early mission hurdles before embarking on their one-way, decade-long voyage to a comet. See how the saga then culminates with Rosetta and Philae at last unveiling their icy target and achieving an unprecedented touchdown on its surface. Award-winning space writer Peter Bond takes us behind the scenes of this historic endeavor, sharing insights from the international team of scientists and engineers who made the mission possible, describing the remarkable technology that they created, and delving into the treasure trove of scientific discoveries that followed. Recounting in vivid detail the inner workings of Rosetta, this book is a celebration of the mission that has left a lasting impact on planetary science and space exploration.
Ice and Fire: Great Comets to Come was written because a special celestial event climaxes towards the end of 2013 – the arrival, fresh from the Oort Cloud, of Comet C/2012 S1 (ISON). By all predictions – even the most pessimistic ones – this comet is set to be one of, perhaps the most, dazzling comet seen in modern history and has the astronomical world buzzing with anticipation. Skywatchers have already been primed for C/2012 (ISON) earlier in 2013 with the apparition of another naked-eye comet, C/2011 L4 (PanSTARRS), and following C/2012 S1 (ISON) there is the prospect of 2012 K1 (PanSTARRS) reaching naked eye visibility in August 2014. Future bright cometary prospects are also discussed, taking into account the latest predictions. Examining the origin and nature of comets using examples of great comets from the past, this book sets the scene for the arrival of Comet C/2012 S1 and those following it over the next few years in the inner Solar System. Skywatchers and amateur astronomers can learn how to follow, observe and record comets. There is also a guide on how to keep abreast of the latest cometary discoveries and how to use a variety of reputable sources, including publications, websites, programs and apps to visualize and plan observations. The role of the amateur in cometary discovery also is featured, as well as details on how professional astronomers plan to get the most ‘science’ out of cometary apparitions, how and why professionals go about discovering comets, and upcoming plans to visit comets with space probes (and later, perhaps, human visits). Illustrations provide historic images of comets, images from space probes and images of the latest bright comets. Orbital plots and easy-to-follow sky charts are also included. This book is a unique guide that sets the scene by giving a comprehensive history of comets and examples of great comets throughout history and informs the reader about the nature and origins of this spectacular occurence. Expectations are fully covered by explaining not only what the regular person can expect to see, but how amateur astronomers can plan observations and what steps the professionals are taking to ‘get the most science’ from this exciting event.
The Japanese have faithfully preserved their ancient myths as a connected and well ordered system. And as a system, Japanese myths say much about the human condition in the cosmos and about the human place in the cosmic order. Not until now has a book-length, English-language study been released on Japanese mythology. Drawing on his meticulous research, Asianist Peter Metevelis presents this selection of analytic essays that form a mosaic of themes on the primordial world of Japanese myth, adding a rewarding voice to cultural history and the history of ideas around the world. Metevelis shows that, contrary to popular belief, Japanese myths have much in common with other myths around the globe, and are mythically, logically, and symbolically equivalent. This suggests that Japanese culture has always resonated with the rest of the world and provides a valuable touchstone for comparative mythologists. The mythic themes Metevelis explores include: Linkage of birth with death Loss of immortality Containment of souls Effect of time on mortals Creation of the cosmos And many more This incomparable volume also includes detailed notes, bibliographies, and appendices to help further your knowledge of Japanese myth. Under Metevelis's expert guidance, you can expand your understanding of the Japanese myth system, its structure, and its principal actors, and immerse yourself in the ancient Japanese mysteries of the cosmos.

In his major investigation into the nature of humans, Peter Sloterdijk presents a critique of myth - the myth of the return of religion. For it is not religion that is returning; rather, there is something else quite profound that is taking on increasing significance in the present: the human as a practising, training being, one that creates itself through exercises and thereby transcends itself. Rainer Maria Rilke formulated the drive towards such self-training in the early twentieth century in the imperative 'You must change your life'. In making his case for the expansion of the practice zone for individuals and for society as a whole, Sloterdijk develops a fundamental and fundamentally new anthropology. The core of his science of the human being is an insight into the self-formation of all things human. The activity of both individuals and collectives constantly comes back to affect them: work affects the worker, communication the communicator, feelings the feeler. It is those humans who engage expressly in practice that embody this mode of existence most clearly: farmers, workers, warriors, writers, yogis, rhetoricians, musicians or models. By examining their training plans and peak performances, this book offers a panorama of exercises that are necessary to be, and remain, a human being.
The core of what we refer to as ‘the project of modernity’ is the idea that human beings have the power to bring the world under their control, and hence it is based on a ‘kinetic utopia’: the movement of the world as a whole reflects the implementation of our plans for it. But as soon as the kinetic utopia of modernity is exposed, its seemingly stable foundation cracks open and new problems appear: things don’t happen according to plan because as we actualize our plans, we set in motion other things that we didn’t want as unintended side-effects. We watch with mounting unease as the self-perpetuating side-effects of modern progress overshadow our plans, as a foreign movement breaks off from the very core of the modern project supposedly guided by reason and slips away from us, spinning out of control. What looked like a steady march towards freedom turns out to be a slide into an uncontrollable and catastrophic syndrome of perpetual mobilization. And precisely because so much comes about through our actions, these developments turn out to have explosive consequences for our self-understanding, as we begin to realize that, so far from bringing the world under our control, we are instead the agents of our own destruction. In this brilliant and insightful book Sloterdijk lays out the elements of a new critical theory of modernity understood as a critique of political kinetics, shifting the focus of critical theory from production to mobilization and shedding new light on a world facing the growing risk of humanly induced catastrophe.
The book of Second Peter has long troubled biblical scholars and interpreters, who have disputed both its authorship and its claims about the imminent return of Christ. In this study, Peter Leithart offers a preterist reading of the epistle, arguing that it describe first-century events rather than the end of history. At the same time, he maintains orthodoxy, avoiding hyper-preterism and affirming both the real future return of Christ and the epistle's authenticity. Leithart's accessible style and powerful arguments make this book a valuable addition to the discussion surrounding the Bible's apocalyptic prophecies.
The idea of a connection between poetry and religion is as old as civilization. Homer consulted the Olympian gods on the fate of the fighters on the plain before Troy, and the poet made the heavenly ones speak. It was through poetry that the gods were brought within reach of human hearing. In the centuries after Homer, the Athenian stage became the setting where gods made their poetic interventions, resolving human impasses and contributing to the emotional synchronization of the public life of the city. Sloterdijk argues that, as with the culture of the Ancient Greeks, all religions inscribe a kind of “theopoetry” at the heart of their cultural life and thought, even as they strenuously obscure these poetic origins through the cultivation and enforcement of orthodox norms. Sloterdijk also shows how, in conditions of religious pluralism, religions poetically reshape themselves to accommodate the demands of the religious marketplace. This highly original study of the poetic devices that inform accounts of the otherworldly offers a new interpretation of religious practice and its theological elaboration through history, as well as a fresh perspective on our contemporary age in which collective life, interwoven with imaginative fabrications, is fraying under critical stress.
Thinker on Stage is Peter Sloterdijk's audacious, empathetic reading of Friedrich Nietzche's first published work, The Birth of Tragedy out of the Spirit of Music. Intended originally as a postscript to a new edition of Nietzsche's book, Sloterdijk's text grew and became a book in its own right. Sloterdijk characterizes Nietzsche as a centaur-a philologist/musician, a philosopher/poet; the possessor of multiple talents inseparable from one another-who, in consequence, led the life of an obscure outsider on the fringes of organized cultural life. To Sloterdijk, Nietzsche is not a hairsplitting philologist behind a lecturn but rather a thinker on stage, enacting a psychodrama on the origins of tragedy in universal human suffering. Reaching beyond philology, and risking his career, Nietzsche used this stage to present a glimpse of Greek antiquity quite unlike that cherished in nineteenth-century bourgeois culture. Sloterdijk, in turn, uses his subtle reading of Nietzsche to make his own cultural evaluations. Above all, he finds in The Birth of Tragedy, and in Nietzsche's life, a refutation of the will to power, and a sign that Nietzsche-fragile, wounded, endangered, yet self-affirming-is our contemporary.

All thoughtful leaders can admit experiences of ongoing incompetence--dilemmas, decisions, and even debacles that make them question how they became leaders in the first place. When we look at St. Peter, however, we see a great leader who engaged with his weaknesses and knew his shortcomings. By following his example, we become better leaders in any arena. Seminary president Peter Lillback's profound treatment of more than 100 principles drawn from St. Peter helps you to think through your management style, communication, decision-making, and more. Practical spiritual exercises put the lessons of each short chapter into action--bringing joy to our hearts, guidance to our lives, and help to our service"--From publisher's description.
