How Does the Aurora Borealis Form?

Seeing the Northern or Southern Lights is an awe-inspiring experience, but do you know the science behind their beauty? This video from Per Byhring and the physics department at the University of Oslo explains how particles originating from deep inside the core of the Sun creates aurorae in the atmosphere of Earth.

The video takes a look at how cloud of electrically charged particles emanate from the Sun, and what happens when this plasma reaches the Earth and interacts with the planet’s magnetic field, which creates fantastic light shows in the extreme northern and southern latitudes.
