The temperature above the surface of the Sun is millions of degrees hotter than the actual surface. At this temperature, collisions between gas molecules are frequent and explosive. Electrons and protons released from the explosions are blown towards the Earth by the solar wind. The charged particles are primarily deflected thanks to the Earth's magnetic field. However, the magnetic field is weaker at the poles, and some particles can enter the atmosphere, causing collisions with gas particles. These collisions emit light that we perceive as the dancing lights of the north - Aurora borealis.
In ancient times we did not know the scientific explanation for the lights and made up stories to grasp something so supernatural. Some believed it to be the spirits of their ancestors. Others thought the aurora to be a bridge to the sky built by the gods.
Though we now know the scientific explanation, the magical lights still spark our imagination and awe. The Aurora green earrings are precisely that - you think you grasp their whole being, yet there seems to be something deeper hidden in the mystical green.
