"How to Observe the Sun Safely, 2nd Edition" gives all the basic information and advice the amateur astronomer needs to get started in observing our own ever-fascinating star. Unlike many other astronomical objects, you do not need a large telescope or expensive equipment to observe the Sun. And it is possible to take excellent pictures of the Sun with today's low-cost digital cameras! This title concentrates on providing practical, on-the-spot advice to the amateur astronomer who is interested in observing the Sun, using commercially available equipment. This book surveys what is visible on the Sun, before describing how to record solar features and measure solar activity levels. There is also an account of how to use H-alpha and Calcium-K filters to observe and record prominences and other features of the solar chromosphere, the Sun's inner atmosphere. Because we are just entering a period of high activity on the Sun, following a long, quiet period, many more amateur astronomers will become interested in observing it. The second edition includes an update of Chapter 2 to reflect advances in solar observing equipment since 2002, and a section on building a solar projection box, originally included in the main body of this chapter has been moved to Appendix A. Also Chapter 6 thru 8 have been completely revised to give amateur astronomers advice on how to use film to photograph the Sun, and how to use digital cameras. This new edition also includes more than twice as many illustrations as the first and almost half of them new images.

Our sun is one star among 50 billion in the galaxy. Our galaxy is only one among 50 billion in the universe. With a vastness this incomprehensible, it is easy to feel like we are mere specks of sand on an endless shore. But our sun is special. Though roughly 150 million kilometers separate us, we could not be more connected. Literally, everything you see comes from the sun. The words you are reading now are really photons that left the sun about 8 minutes ago only to bounce off this page and into your eyes. We owe our very existence to our sun. It provides just enough heat to keep our fragile bodies from freezing to ice or burning to a crisp. Every bite of food we eat we owe to the sun, whose energy is converted into plants that provide sustenance for everything up the food chain. DIV /divDIVWe have understood the sun’s importance for millennia. The earliest humans, awestruck by its blazing splendor, left drawings of the sun on cave walls. Nearly every civilization, no matter where it sprang up on the planet, has revered the sun. Myths about the sun were the basis of the earliest deities of ancient Sumerian, Hindu, Egyptian, Chinese, and Meso-American cultures. Before Apollo, the ancient Greeks worshiped the sun-god Ares. Before Zeus, the ancient Romans worshiped Sol./divDIV /divDIVThroughout our history, the sun has been central to humanity’s quest for meaning in the universe. But our history has been a brief moment in our sun’s 4.5 billion year life. Only recently, through advances in science and technology, have we begun to understand our sun - where it came from, how it functions, how it affects our lives and how it eventually will destroy our planet./divDIV /divDIVOur Sun is a comprehensive, easy-to-understand guide to everything we know about our closest star. Illustrated with stunning pictures from NASA’s newly-launched Solar Dynamics Observatory, Our Sun will reveal the science behind the sun, trace its impact on human history, and reveal its growing importance to our future way of life./div

It's a good story: we are made of matter like that we also find in the stars. Essential to our planet's existence, the Sun--our nearest star--is also the most fascinating object humans have ever adored, literally the difference between day and night. But getting beyond these basic perceptions requires scientific understanding. What, for instance, is the sun made of? Why does it burn so brightly? How long will it last? This book not only answers these questions but also tells the story of how we came to know--not merely behold--the grandest entity in our sky. Leon Golub and Jay M. Pasachoff offer an engaging and informative account of solar science and its history, drawing on centuries of study by solar astronomers who have looked to the Sun not only to learn about our own solar system but also about what lies in the distant wilderness of faintly glimmering stars. They skim along the surface of the Sun, which is decorated with sunspots, discussing these fascinating magnetic aberrations and the roughly eleven-year cycles they abide. They follow seismic waves into the interior of the Sun and its unending nuclear fusion. They show us what is unveiled in solar eclipses and what new views and knowledge our space exploration has afforded us. They brave solar weather, and they trace the arcs of radiation and particles whose effects we can see on earth in phenomena such as the northern and southern lights. Glowing with a wide assortment of astonishing images, this beautifully illustrated guide will delight everyone, from those who know what a coronagraph is to those who simply like to step out on a bright day, close their eyes, and feel the Sun's warmth upon their skin.
