The celestial phenomena, named Aurora Borealis by Galileo Galilei (italian astronomer, mathematician and philosopher) is a light phenomena often seen in the northern regions.

The light or solar particles originates from large explosions and flares (coronal mass ejection) on the sun and thrown into space, then captured by earth’s magnetic field, concentrated on the geomagnetic north pole and south pole.

These particles then collide with earth’s atmospheric gasses, which acts as an effective protective shield for these deadly particles. The collision between the particles and gasses causes photons to be emitted, which are visible only in huge amounts to the human eye.

It’s a spectacular sight, the light moves over the sky like a curtain in the wind. The light is common in the winter months all over Greenland. To capture the light with a camera requires the shutter speed set to 10-20 seconds, aperture set to lowest number and an ISO setting between 200 and 800. Remember to turn off the flash. Because of the long exposure times a tripod is required.

These photos were shot on 6’th of march 2007 on a cold and clear night in Nuuk. The northern light were so powerful that night, you could see the reflection in the water.
