If you follow my blogs, then you know I love those time-lapse videos of the Northern lights. Yes, the “Aurora Borealis”. I always thought those lights are created due to the combination of pressure, temperature, atmosphere, and something to do with Nitrogen. Wrong! It turns out those lights were “created” by the sun’s magnetic field and plasma discharges. This video breaks it down, it explains how particles originating from deep inside the core of the sun creates northern lights, also called aurora borealis, on our planet.
In simple (and funny English), the sun is a giant crock pot of magnetic fields and incredible heat. The two collude and send giant belches of plasma shooting outward toward our little rock. When the magnetically charged package hits our planet’s atmosphere, the plasma is siphoned downward to our skies, where we see pretty swirling lights, and not a violent cosmic grappling match.
