Bright Aurora Borealis over Sweden

Astrophotographer Karsten Berger: "The fast solar wind did not disappoint. Even with a nearly full Moon and bright lights of the surrounding houses they were clearly visible to the naked eye."

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.
