The story of the turbulent space around the sun—and the artisans and scientists who revealed its nature, elucidating the origins and fate of the solar system.We often imagine the solar system as a family of planets orbiting placidly around the sun, all against an empty black background. But our solar system swims in a perilous medium carved out by the sun’s solar wind: the heliosphere.The Turbulent Sun takes us on a journey through this vast hazard-filled bubble enveloping our cosmic ecosystem. In vivid detail, Leon Golub tells the story of the heliosphere as it emerged, then stretched and compressed over billions of years, shaping the solar system as we know it today. He reveals how the sun’s magnetic cocoon shielded Earth from dangerous galactic radiation, leaving it habitable, as fierce storms of solar wind stripped away the atmospheres of other planets.The result is a stunning tale not just of our cosmic origins but of science in the making. Glassmakers painstakingly measured the bending of light while photographers captured the sun in unprecedented detail, and chemists probed the energy states of the atom. Today, spacecraft are flying closer than ever to the sun, exposing the hazardous effects of space weather and mapping the future of the heliosphere as it sails through the galaxy. As Golub reminds us, scientific progress is never linear; it entails unexpected discoveries, serendipity and dead ends, and most importantly, cooperation across disciplines and borders.

How did the Sun evolve, and what will it become? What is the origin of its light and heat? How does solar activity affect the atmospheric conditions that make life on Earth possible? These are the questions at the heart of solar physics, and at the core of this book. The Sun is the only star near enough to study in sufficient detail to provide rigorous tests of our theories and help us understand the more distant and exotic objects throughout the cosmos. Having observed the Sun using both ground-based and spaceborne instruments, the authors bring their extensive personal experience to this story revealing what we have discovered about phenomena from eclipses to neutrinos, space weather, and global warming. This second edition is updated throughout, and features results from the current spacecraft that are aloft, especially NASA's Solar Dynamics Observatory, for which one of the authors designed some of the telescopes.

Essential for life on earth and a major influence on our environment, the Sun is also the most fascinating object in the daytime sky. Every day we feel the effect of its coming and going – literally the difference between day and night. But figuring out what the Sun is, what it’s made of, why it glows so brightly, how old it is, how long it will last – all of these take thought and observation.Leon Golub and Jay M. Pasachoff offer an engaging and informative account of what scientists know about the Sun, and the history of these discoveries. Solar astronomers have studied the Sun over the centuries both for its intrinsic interest and in order to use it as a laboratory to reveal the secrets of other stars. The authors discuss the surface of the Sun, including sunspots and their eleven-year cycle, as well as the magnetism that causes them; the Sun’s insides, as studied mainly from seismic waves that astronomers record on its surface; the outer layers of the Sun that we see from Earth only at eclipses and from spacecraft; and space weather, the radiation and particles that we on Earth receive from the Sun in flares or other ejections. Golub and Pasachoff also provide instructions on how to observe the Sun safely, and how to attend and to observe solar eclipses.Illustrated with a wide variety of beautiful solar images, this informative book will appeal to both scientists and a more general readership interested in this star at the centre of our solar system.Published in association with the Science Museum, London.
