Sublime, magnificent time lapse short film of northern aurora colors,

particles from the sun intersecting w our planet's atmosphere,

reminder of Earth's life protecting thin blue layer ... and it's very thin

Northern Lights ('Aurora borealis' in the north and 'Aurora Australis' in the south), a result of collisions between gaseous particles in the Earth’s atmosphere and charged particles released from the Sun’s atmosphere. The different colours are attributed to different types of gas particles colliding; the most commonly occurring colour, a pale yellow/green, is created by oxygen molecules located about 60 miles above the earth. Nitrogen produces a blue, or purple/read aurora, and the elusively rare red aurora is created by high altitude oxygen.
