Northern Lights over Arkansas…

30 Oct

 Q. How do you know when the Earth has experienced a particularly impressive display of the Northern Lights?

A.When somebody can take a picture like the one above in Arkansas.

Photographed by Brian Emfinger in Ozark, Arkansas, these auroras were triggered by a big coronal mass ejection—a burst of energy from the Sun that can interact with our atmosphere to produce particularly spectacular examples of the aurora borealis.

If you missed the light show last night,  Spaceweather.com has a collection of photos taken around the world, from Michigan to Norway.
