The closest star to our planet Earth is the Sun, the central and perhaps the most impolrtant element of our solar system. The Sun shapes our lives through its life-sustaining heat and its often spectacular actions--the eclipses and sunspots, the eleven-year solar cycle and the enormous solar flares that shoot arcing tongues of flame millions of miles abouve the Sun's surface. The recent Skylab and Solar Maximum missions revolutionnized our understanding of these and other sources, noted astronomer and teacher Donat G. Wentzel presents an informative portrait of our closes star. Our Sun exhibits amazing physical properties: the seething core, where enormous pressure fires the nuclear reactions that radiate light and heat: the surface layers, where fiery gases are in constant motion (except in the relative "peace" of dark sunspots): and the crona, which reaches temperatures of more than one million degrees Fahrenheit. Going beyond the physical description, Wentzel give the reader a broad perspective on contemporary solar science. Can we predict how changes in the Sun will influence life on earth? Is our Sun a "typical"star?
