Whether you know them as the northern or southern lights, auroras are one of nature’s most dazzling spectacles. It’s hard not to marvel—why do they exist? Joan Marie Galat explores the answer in this addition to the Dot to Dot in the Sky series, revealing the incredible cosmic circumstances that lead to such brilliant displays of light.
Find out what happens when solar winds strike the Earth’s atmosphere and electrical and magnetic forces react together. Then go back in time to discover how ancient cultures explained the mysterious lights. Meet a Norse frost giant that refuses to marry, a chief who follows his son across the Milky Way, and a seven-headed monster yet to lose a fight. From celestial fires to dancing spirits, auroras have taken many meanings over time. These rich tales, with stunning illustrations and full-colour photographs, are the perfect way to discover this spectacular phenomenon for yourself.
