Ancient peoples saw these displays as souls of the dead, the torches of the spirits and as harbingers of war. Barely 100 years ago, scientists finally learned that an aurora is created when the Earth's magnetic field is bombarded with charged particles from the sun. When the charged particles collide with oxygen in the atmosphere, auroras with yellows, greens and reds appear. Collisions with nitrogen result in bluish colors. However, our understanding of the physics behind auroras has not detracted from their wonder. \u003c\/p\u003e\u003cp\u003e \u003ci\u003eAuroras\u003c\/i\u003e is filled with 80 photographs of one of nature's greatest spectacles, complete with captions that reflect on the folklore, science and beauty of the northern lights.
