Aurora Borealis

Also known as the Northern Lights. The dancing lights of the aurora are collisions between electrically charged particles from the sun that enter the earth's atmosphere. Northern lights may appear in many colours as seen in my photos, with green, pink being the most common. Often times our vision is unable to pick up the colour of the lights and they may only appear as gray clouds moving through the sky. This is due to the way our eyes work. We have 2 types of receptors in our eyes, rods, and cones. Rods are our night vision, almost everything is seen in black and white. Cones are our colour vision, they are great for seeing colour but require much more light.
