Brilliant Time Lapse of Alaska's Northern Lights

360 Time Lapse Of Northern Lights

Aurora Borealis - Northern Lights

Magic in the sky! 😍 The Northern Lights (Aurora borealis) are caused by collisions between electrically charged particles from the sun that enter our earth’s atmosphere. The green colours come from reactions with oxygen atoms, red from both oxygen and nitrogen. The purple, pink and blue colours come from nitrogen alone. | BBC Earth
