We call optical phenomena any observable event that results from the interaction of light and matter.
Among the most fascinating optical phenomena we can observe the so-called polar light, characterized by luminous trails in the sky that assume different colours depending on the gases in the air.
How does the sky give birth to this charming spectacle of lights?
Polar light, also called The Northern Light in the northern hemisphere, takes shape when electric particles (electrons and protons) coming from the sun (solar wind) enter in contact with the Earth's magnetic field.
This collision generates a large amount of energy that is transformed into visible light. The oxygen atoms emit green and red light, nitrogen ones deep red, blue and purple flashes and all these colours blend each other in a dance of sinuous shades. This spellbound vision finally reveals to the Spect-Actors’ eyes; thus let the magic enchant you!
