During long winter nights, the light of the aurora borealis appears over the sparcely populated north. Little is known, however, about these dazzling displays of ghostly light and movement. The author discusses the history, mythology, and science behind auroras. Demonstrating the influence of the sun in the aurora's creation, he also compares the northern lights with phenomena such as lightning and rainbows. Lavishly illustrated with numerous color and black and white pictures, Aurora offers a comprehensive understanding of a mysterious dynamic that has fascinated and even alarmed northern communities through the ages.

This new book addresses a gap in the literature, offering an explanation of the aurora's causes, how the occurrence of major events may now be predicted, and how amateur observers can go about recording displays. This is the first serious book about aurora written for practical but non-professional observers. It provides a concise accessible description of the various auroral forms and how to record them, illustrated with color images of recent displays. It contains details of 'Space Weather' forecasting websites, how to interpret and use the information given on these, and how to anticipate auroral activity.

The Sun has been an object of scientific interest since the time of the ancient Greeks. The vast amounts of observational data acquired in recent years have led to a greatly improved knowledge of the physics of the Sun. With a minimum of technicalities, this book gives an account of what we now know about the Sun's interior, its surface and atmosphere, its relation to the solar system including the earth, and its relation to other stars. The way that solar power is being converted to useful forms of energy is explained. The book is aimed at anyone with a broad science background interested in learning about the latest developments in solar studies, from those at high-school level to the non-specialist professional.

Emphasizing sustainability, balance, and the natural, green dominates our thinking about ecology like no other color. What about the catastrophic, the disruptive, the inaccessible, and the excessive? What of the ocean’s turbulence, the fecundity of excrement, the solitude of an iceberg, multihued contaminations? Prismatic Ecology moves beyond the accustomed green readings of ecotheory and maps a colorful world of ecological possibility. In a series of linked essays that span place, time, and discipline, Jeffrey Jerome Cohen brings together writers who illustrate the vibrant worlds formed by colors. Organized by the structure of a prism, each chapter explores the coming into existence of nonanthropocentric ecologies. “Red” engages sites of animal violence, apocalyptic emergence, and activism; “Maroon” follows the aurora borealis to the far North and beholds in its shimmering alternative modes of world composition; “Chartreuse” is a meditation on postsustainability and possibility within sublime excess; “Grey” is the color of the undead; “Ultraviolet” is a potentially lethal force that opens vistas beyond humanly known nature. Featuring established and emerging scholars from varying disciplines, this volume presents a collaborative imagining of what a more-than-green ecology offers. While highlighting critical approaches not yet common within ecotheory, the contributions remain diverse and cover a range of topics including materiality, the inhuman, and the agency of objects. By way of color, Cohen guides readers through a reflection of an essentially complex and disordered universe and demonstrates the spectrum as an unfinishable totality, always in excess of what a human perceives.

Science, biography, and arctic exploration coverage in this extraordinary true story of the life and work of Norwegian scientist Kristian Birkeland, the troubled genius who solved the mysteries of one of nature’s most spectacular displays. Captivated by the otherworldly lights of the aurora borealis, Birkeland embarked on a lifelong quest to discover their cause. His pursuit took him to some of the most forbidding landscapes on earth, from the remote snowcapped mountains of Norway to the war-torn deserts of Africa. In the face of rebuke by the scientific establishment, sabotage by a jealous rival, and his own battles with depression and paranoia, Birkeland remained steadfast. Although ultimately vindicated, his theories were unheralded—and his hopes for the Nobel Prize scuttled—at the time of his suspicious death in 1917. The Northern Lights offers a brilliant account of the physics behind the aurora borealis and a rare look inside the mind of one of history's most visionary scientists.

Heliophysics is a fast-developing scientific discipline that integrates studies of the Sun's variability, the surrounding heliosphere, and the environment and climate of planets. Over the past few centuries, our understanding of how the Sun drives space weather and climate on the Earth and other planets has advanced at an ever increasing rate. This 2010 volume, the last in this series of three heliophysics texts, focuses on long-term variability from the Sun's decade-long sunspot cycle and considers the evolution of the planetary system over ten billion years from a climatological perspective. Topics covered range from the dynamo action of stars and planets to processes in the Earth's troposphere, ionosphere, and magnetosphere and their effects on planetary climate and habitability. Supplemented by online teaching materials, it can be used as a textbook for courses or as a foundational reference for researchers in fields from astrophysics and plasma physics to planetary and climate science.

Perturbation electric and magnetic fields carry in excess of 10(exp10) to 10(exp12) W of electrical power between the magnetosphere and high-latitude ionosphere. Most of this power is generated by the solar wind. The ionosphere at large spatial and temporal scales acts as a dissipative slab which can be characterized by its height-integrated Pedersen conductivity sigma p, so that the power flux into the ionosphere due to a quasi-static electric field E is given by sigma (pE2) The energy transferred to the ionosphere by time-varying electromagnetic fields in the form of Alfven waves is more difficult to calculate because density and conductivity gradients can reflect energy. Thus, field resonances and standing wave patterns affect the magnitude and altitude distribution of electrical energy dissipation. We use a numerical model to calculate the frequency-dependent electric field reflection coefficient of the ionosphere and show that the ionosphere does not behave as a simple resistive slab for electric field time scales less than a few seconds. Time variation of spacecraft-measured high-latitude electric and perturbation magnetic fields is difficult to distinguish from spatial structuring that has been Doppler-shifted to a non-zero frequency in the spacecraft frame. However, by calculating the frequency-dependent amplitude and phase relations between fluctuating electric and magnetic fields we are able to show that low frequency fields (
