Auroras are a very beautiful natural light display in the sky particularly in the high latitude (Arctic and Antarctic) regions, caused by the collision of energetic charged particles with atoms in the high altitude atmosphere (thermosphere).
Best Aurora Wallpapers is a selected collection of Flickr images which are excellent images to set as backgrounds of your phone.
