Aurora Borealis over Four Mile Lake in Alberta, Canada

Astrophotographer John David McKinnon: "The Aurora Borealis dancing over Four Mile Lake on a perfectly peaceful fall night."

Known as the northern lights (aurora borealis) or southern lights (aurora australis), auroras are colorful, dynamic, and often visually delicate displays of an intricate dance of particles and magnetism between the Sun and Earth called space weather. When energetic particles from space collide with atoms and molecules in the atmosphere, they can cause the colorful glow that we call auroras.
