Discover the incomparable beauty of the Northern Lights with this accessible guide for aspiring astronomers and seasoned night sky observers. Covers the essential equipment needed for observation and photography and full of stunning photographs.
A mother-daughter story of an adventure-filled search for the amazing aurora borealis. Alix and her mom are fascinated by the nighttime light displays in the sky known as auroras, or northern lights, but being able to see them in person proves to be more challenging than expected. Where do they appear? When? How could Alix and her mom get there to see the auroras before they disappear from the sky? Inspired by the authors’ own experiences, A Search for the Northern Lights brings the reader along on a fascinating journey as Alix and her mom eagerly learn what auroras are and how to find them. The book also includes science and more information on auroras, plus a helpful guide for those hoping to catch their own glimpse of the incredible northern lights.
Mindy Dwyer captures the magic of the Northern Lights in a story that is written like a legend passed down through generations. With her bright, luminous illustrations and clear language, Dwyer tells the story of Aurora, a young girl who takes a journey of discovery and collects the colors from the sky to comfort her. Full color.
My first book, “Brainbow,” was put together using family photos, as a therapy of sorts, to help me remember my life before my accident. My second book, “Aurora’s Brain,” attempts to bring the concept of the brain to the conscious level. “Aurora’s Dream” attempts to bring the important life concepts of senses, thinking, and learning to the conscious level for readers. Then it “zooms” in on the also important concepts of healthy, happy, and hungry. It is through research and therapy for brain-injured patients that breakthroughs in Neuroscience occur. With my simple understanding of how my own brain works, gleaned from putting my brain and life back together after temporarily losing everything I had ever learned or knew, I created a picture language that I call “Circlatin”. I used Circlatin to teach myself how to think again and make the many decisions necessary to reprogram my scrambled computer brain. I’m hoping that with Circlatin, wonderful artwork or a circle to go with each paragraph, and a few helping words from me that I can inspire elementary students to want to gain a better understanding of their own brains. Maybe they will want to reprogram their brains like Aurora did. Maybe after reading “Aurora’s Dream” they will want to learn to draw their brains, thoughts and feelings with Circlatin so that they can “see” what they are thinking before they think, speak and act. We can’t “see” our brains, or feel them beating as we can with our hearts, but our brain controls everything we do! “If we could build a computer that could do everything our brain can do, it would be as tall as a skyscraper!” Kathy Elgin, “The Human Brain”
In helping someone I love, I lost my life. Or did I? Cut off from my body, I live in the home of a god who’s willing to train me, to help me fully embrace my powers, both as a witch and as a reaper. But while I lay in a coma, the men I left behind suffer, desperate to find a way to bring me back. I want to return to them, but our family is not complete. One is missing, a member of the coven who was lost before they found me. And I must go on a quest to Purgatory and bring him back, or we’ll forever be incomplete. I’m coming home to my men, to my family, but will my return bring relief or doom us all?
The aurora is the most visible manifestation of the connection of the Earth to the space environment and has inspired awe, curiosity, and scientific inquiry for centuries. Recent advances in observing techniques and modeling and theoretical work have revealed new auroral phenomena, provided a better understanding of auroral dynamics, and have led to an enhanced capability for auroral forecasts. This monograph features discussions of: New auroral phenomena due to the ring current ion and polar rain electron precipitation Various auroral forms and hemispheric asymmetry Auroral model development and MHD simulations Application of the auroral observations for radio absorption and scintillation Aurora nowcast and forecast for space weather operations Auroral Dynamics and Space Weather is a valuable contribution for scientists, researchers, space weather operators, and students of Earth's space environment.
Over the past two decades auroral science has developed from a somewhat mysterious and imprecise specialty into a discipline central in the study of the ionosphere and magnetosphere. The investigation of aurora unites scientists with very different backgrounds and interests so that it is difficult to write a self-contained account of the field in a book of reasonable length. In this work I have attempted to include those aspects of theory which I have found valuable in predicting the effects on the atmosphere of auroral particle precipitation. In addition I have attempted to describe the techniques of observation with particular emphasis on optical methods which have been useful. While the aeronomy of aurora has been regarded as central, the mechanisms by which particles are accelerated and precipitated into the atmosphere is of no less interest. This aspect of the subject has however been treated in a briefer fashion since it is a part of the immense and rapidly developing field of magnetospheric science. Generally I have attempted to provide a coherent introduction to auroral science with an emphasis on relatively simple physical interpretations and models. References are given to enable the reader to find more extensive or rigorous discussions of particular topics. A fairly complete, quantitative atlas of the auroral spectrum is included.
