Northern Lights caught on camera over Minnesota

An amazing and surreal spectacle was caught on camera in the skies over Minnesota.

The video shows the northern lights glowing green and flashing over the skies near Wheaton.

The phenomenon is also known as the Aurora Borealis, and it's caused by something called a coronal mass ejection, or CME.

That's when the sun releases a massive burst of solar wind, sending billions of particles into space.

NASA says the CME hit earth's magnetic field last weekend.

It caused a geomagnetic storm that we see here on Earth as the northern lights.

NASA also says CMEs can affect electronic systems in satellites and on the ground.
