The northern lights are spectacular for more than just their beauty.
They're also one of the most mysterious phenomena on Earth. Or at least, were at one point.
The video below gives a stunning look at just how these seemingly mystical waves come to be. Did you know that the northern lights are actually created after the sun ejects energy from its core?
Even if you're not a fan of awesome light, this video will get you at least one step closer to becoming an astrophysicist -- sort of.
