It was a lucky twist of fate when in the early1980s David Levy, a writer and amateur astronomer, joined up with the famous scientist Eugene Shoemaker and his wife, Carolyn, to search for comets from an observation post on Palomar Mountain in Southern California. Their collaboration would lead to the 1993 discovery of the most remarkable comet ever recorded, Shoemaker-Levy 9, with its several nuclei, five tails, and two sheets of debris spread out in its orbit plane. A year later, Levy would be by the Shoemakers' side again when their comet ended its four-billion-year-long journey through the solar system and collided with Jupiter in the most stunning astronomical display of the century. Not only did this collision revolutionize our understanding of the history of the solar system, but it also offered a spectacular confirmation of one scientist's life work. As a close friend and colleague of Shoemaker (who died in 1997 at the age of 69), Levy offers a uniquely insightful account of his life and the way it has shaped our thinking about the universe.

Early in his training as a geologist, Shoemaker suspected that it wasn't volcanic activity but rather collisions with comets and asteroids that created most of the craters on the moon and most other bodies in the solar system. Convincing the scientific community of the plausibility of "impact theory," and revealing its power for penetrating mysteries such as the extinction of the dinosaurs and the timing of the Earth's eventual demise, became Shoemaker's mission. Through conversations with Shoemaker and his family, Levy reconstructs the journey that began with a young geologist's serious desire to go to the moon in the late1940s. Sent by the government to find a way to harvest plutonium, Shoemaker instead found evidence in desert craters for what became his impact theory. While he never became an astronaut, he did become the first geologist hired by NASA and subsequently set the research agenda for the first manned lunar landing.

After a series of victories and setbacks for Shoemaker, the collision of Shoemaker-Levy 9 with Jupiter provided the most convincing proof to date of the role of impacts in our solar system. Levy's explanation of the scientific reasoning that guided Shoemaker in his career up to this dramatic point--as well as his personal portrait of a man who found white-water rafting to be an easy way to relax--sets these fascinating events in a human scale. This biography shows what Shoemaker's legacy will be for our understanding of the story of the Earth well into the twenty-first century.

Cometography is a multi-volume catalog of every comet observed throughout history. It uses the most reliable orbits known to determine the distances from the Earth and Sun at the time a comet was discovered and last observed, as well as the largest and smallest angular distance to the Sun, most northerly and southerly declination, closest distance to the Earth, and other details to enable the reader to understand the physical appearance of each well-observed comet. Volume 5 provides a complete discussion of the observations and pertinent calculations for every comet seen between 1960 and 1982. The comets are listed in chronological order, with complete references to publications relating to each comet and physical descriptions of each comet's development throughout its apparition. Cometography will be valuable to historians of science as well as providing amateur and professional astronomers with a definitive reference on comets through the ages.

The cycle of day and night and the cycle of seasons are two familiar natural cycles around which many human activities are organized. But is there a third natural cycle of importance for us humans? On 13 March 1989, six million people in Canada went without electricity for many hours: a large explosion on the sun was discovered as the cause of this blackout. Such explosions occur above sunspots, dark features on the surface of the Sun that have been observed through telescopes since the time of Galileo. The number of sunspots has been found to wax and wane over a period of 11 years. Although this cycle was discovered less than two centuries ago, it is becoming increasingly important for us as human society becomes more dependent on technology. For nearly a century after its discovery, the cause of the sunspot cycle remained completely shrouded in mystery. The 1908 discovery of strong magnetic fields in sunspots made it clear that the 11-year cycle is the magnetic cycle of the sun. It is only during the last few decades that major developments in plasma physics have at last given us the clue to the origins of the cycle and how the large explosions affecting the earth arise. Nature's Third Cycle discusses the fascinating science behind the sunspot cycle, and gives an insider's perspective of this cutting-edge scientific research from one of the leaders of the field.

This volume contains Euler's early astronomical tables and his First theory of the moon of 1753.

As we speak, stunning new snapshots of our Solar System are being transmitted to Earth by a fleet of space probes, landers, and rovers. Yet nowadays, it is all too easy to take such images for granted amidst the deluge of competing visuals we scroll through every day. To truly understand the value of these incredible space photos, we first need to understand the tools that made them possible. This is the story of imaging instruments in space, detailing all the technological missteps and marvels that have allowed us to view planetary bodies like never before. From the rudimentary cameras launched in the 1950's to the cutting-edge imaging instruments onboard the Mars Perseverance rover, this book covers more than 100 imaging systems sent aboard various spacecraft to explore near and distant planetary bodies. Featured within are some of the most striking images ever received by these pioneering instruments, including Voyager's Pale Blue Dot, Apollo's Blue Marble, Venera's images from the surface of Venus, Huygens' images of Titan, New Horizon's images of Pluto and Arrokoth, and much more. Along the way, you will learn about advancements in data transmission, digitization, citizen science, and other fields that revolutionized space imaging, helping us peer farther and more clearly across the Solar System.

Unless they research the subject for themselves, many people do not realise that the origins and development of the human entity are largely an unresolved mystery. Before the Author's own research, he was among them. He found that he also had been subtly indoctrinated with such remarks 'cousins' and 'relatives' with regard to the apes and assumed like most others, that all the facts where in. When you read the work, you will find that this is simply not true. So begins 'The Human Enigma', a truly epic enquiry into the origins of our world and the creatures that walk upon. In particular, it examines the human brain as a uniquely wonderful creation which can be viewed as a gift from God (or was it the gods?) besides Darwinian evolution and Biblical creation. This book explores the fanatic proposition that mankind's rapid development with regard to the human brain may have been influenced by extra terrestrial sources. This work refers to, and draws together the previous work of respected scientists and looks at the future scenarios that the latest genetic and environmental sciences are pointing towards.

Popular culture is flourishing again, with a renewed interest in the ET and UFO phenomena. We are inundated with films, TV programmes and books, plus many conspiracy theories, dealing with the phenomena. Governments and security agencies are denying any interest in the issue, yet releasing masses of documents (mostly unreadable) after being compelled to, by the Freedom of Information Act. Such speculation and documentation in ancient writings suggests that an unearthly presence has been in Earth-space for many generations. The question of this situation must reach a culminating point sometime in the near future. This book is concerned with the cultural shock and social disorientation that would obviously occur with a sudden appearance en-mass of an alien race finally revealing themselves to humanity and how the people of Earth would react.

This is a work that examines the many mysteries and anomalies regarding our Moon. It has been said that there is no scientific consensus of opinion regarding the Moon and its origins. A scientist also stated, By all known cosmic laws the Moon should not be there. Over 800 lbs of Moon rock have been retrieved that instead of explaining the Moon and its mysteries, have only introduced more, and are still being puzzled over. Reports of white coloured lights have been observed on the Moon and are often seen moving. They have been recorded in astronomical journals for years. Structures and symmetrical objects that look like machines have been seen and photographed and are logged in NASA files and photographs. UFO's have been seen trailing and preceding Apollo craft and have been seen in proximity to the moon by all the Apollo missions. This book deals with them all and also introduces an interesting speculative theory regarding the possible origins of our Moon.

Fully updated throughout, including revised illustrations and new images from NASA missions, this new edition provides an overview of Earth's history from a planetary science perspective for Earth science undergraduates. Earth's evolution is described in the context of what we know about other planets and the cosmos at large, from the origin of the cosmos to the processes that shape planetary environments and from the origins of life to the inner workings of cells. Astronomy, Earth science, planetary science and astrobiology are integrated to give students the whole picture of how the Earth has come to its present state and an understanding of the relationship between key ideas in different fields. The book presents concepts in nontechnical language and mathematical treatments are avoided where possible. New end-of-chapter summaries and questions allow students to check their understanding and critical thinking is emphasized to encourage students to explore ideas scientifically for themselves.

All magnetized planets in our solar system (Mercury, Earth, Jupiter, Saturn, Uranus, and Neptune) interact strongly with the solar wind and possess well developed magnetotails. However, Mars and Venus have no global intrinsic magnetic field, yet they possess induced magnetotails. Comets have a magnetotail that is formed by the draping of the interplanetary magnetic field. In the case of planetary satellites (moons), the magnetotail refers to the wake region behind the satellite in the flow of either the solar wind or the magnetosphere of its parent planet. The largest magnetotail in our solar system is the heliotail, the magnetotail of the heliosphere. The great differences in solar wind conditions, planetary rotation rates, ionospheric conductivity, and physical dimensions provide an outstanding opportunity to extend our understanding of the influence of these factors on magnetotail processes and structure. Volume highlights include: * A discussion of why a magnetotail is a fundamental issue in magnetospheric physics * A unique collection of tutorials that cover a large range of magnetotails in our solar system * A comparative approach to magnetotail phenomena, including reconnection, current sheet, rotation rate, plasmoids, and flux robes * A review of global simulation studies of the effect of ionospheric outflow on the magnetosphere-ionosphere system dynamics Magnetotails in the Solar System brings together for the first time in one book a collection of tutorials and current developments addressing different types of magnetotails. As a result, this book will appeal to a broad community of space scientists and be of interest to astronomers who are looking at tail-like structures beyond our solar system.

Finding our Place in the Solar System gives a detailed account of how the Earth was displaced from its traditional position at the center of the universe to be recognized as one of several planets orbiting the Sun under the influence of a universal gravitational force. The transition from the ancient geocentric worldview to a modern understanding of planetary motion, often called the Copernican Revolution, is one of the great intellectual achievements of humankind. This book provides a deep yet accessible explanation of the scientific disputes over our place in the solar system and the work of the great scientists who helped settle them. Readers will come away knowing not just that the Earth orbits the Sun, but why we believe that it does so. The Copernican Revolution also provides an excellent case study of what science is and how it works.

The two most fascinating questions about extraterrestrial life are where it is found and what it is like. In particular, from our Earth-based vantage point, we are keen to know where the closest life to us is, and how similar it might be to life on our home planet. This book deals with both of these key issues. It considers possible homes for life, with a focus on Earth-like exoplanets. And it examines the possibility that life elsewhere might be similar to life here, due to the existence of parallel environments, which may result in Darwinian selection producing parallel trees of life between one planet and another. Understanding Life in the Universe provides an engaging and myth-busting overview for any reader interested in the existence and nature of extraterrestrial life, and the realistic possibility of discovering credible evidence for it in the near future.

Solar energetic particles (SEPs) emitted from the Sun are a major space weather hazard motivating the development of predictive capabilities. This book presents the results and findings of the HESPERIA (High Energy Solar Particle Events forecasting and Analysis) project of the EU HORIZON 2020 programme. It discusses the forecasting operational tools developed within the project, and presents progress to SEP research contributed by HESPERIA both from the observational as well as the SEP modelling perspective. Using multi-frequency observational data and simulations HESPERIA investigated the chain of processes from particle acceleration in the corona, particle transport in the magnetically complex corona and interplanetary space, to the detection near 1 AU. The book also elaborates on the unique software that has been constructed for inverting observations of relativistic SEPs to physical parameters that can be compared with space-borne measurements at lower energies. Introductory and pedagogical material included in the book make it accessible to students at graduate level and will be useful as background material for Space Physics and Space Weather courses with emphasis on Solar Energetic Particle Event Forecasting and Analysis.
