Mystery solved vote...
The sun sends a constant stream of charged particles, known as the solar wind, into space. These energized particles interact with a protective magnetic shield that shrouds our planet.
Earth's magnetosphere, as the shield is called, is made up of invisible lines of a magnetic field that radiate out into space from the poles. The magnetosphere forces the solar wind to slide around it, protecting the planet from radiation.
The charged particles squeeze the magnetic field into a teardrop shape. In the magnetosphere, researchers say, the interaction creates electric fields and electromagnetic waves that transfer their energy to electrons, which then plunge into the atmosphere.
The charged particles excite oxygen and nitrogen in the atmosphere to create the aurora borealis, or northern lights.

amazing that with all our discoveries, science still hasn't solved the riddle that is the northern lights. Perhaps one day...

Any picture with the Aurora Borealis (northern lights) deserves a vote from me. This is a breath taking scene, one of natures mysterious wonders.
