The sun and skies are present throughout our lives. Yet for many of us, mystery persists about their appearances. Perhaps you have wondered why sunsets are red and clear skies bright blue, or simply enjoyed the gradual transitions of daytime into night. Then this is the book for you. With dozens of beautiful color images and plentiful diagrams, Blue Skies, Red Sunsets and Company guides all of us skywatchers through blue skies to red sunsets, twilight with ethereal crepuscular rays, clouds, to mirages and finally the ultimate moment of sunset known as the green flash.
