The sun has been an object of fascination and scientific interest to humans since the time of the ancient Greeks. With minimum technical language, this book gives an account of what we now know about the sun's interior, its surface and atmosphere, its role in our solar system, and its relation to other stars. The ways that solar power is being converted to useful forms of energy are also explained. The book is aimed at anyone interested in learning about the latest developments in solar studies, from those at high-school level to the nonspecialist professional.

The solar atmosphere, above the Sun's surface layers, reaches mega-kelvin temperatures and high levels of dynamic activity through processes involving a pervading magnetic field. This book explores one of the principal means of understanding the solar atmosphere, its ultraviolet and soft X-ray emission. The ultraviolet and X-ray spectra of the Sun's atmosphere provide valuable information about its nature - the heat and density of its various parts, its dynamics, and chemical composition. The principles governing spectral line and continuous emission, and how spectral studies lead to...
