The northern lights, also known as the aurora borealis, put on remarkable shows of light and motion in high latitudes—Alaska being the perfect place to see them. Shot with ultra-high definition cameras, this book of amazing photographs showcases a period of unusually high solar activity in the northern lights. These new photos take full advantage of the latest advances in photographic technology and the active solar storms of the past several years that cause the lights. With 160 images that have never been collected in book form, this book allows us to witness charged particles in the earth's atmosphere clash with electrons and protons released by the sun.
