The largest solar storm in five years sent a huge wave of radiation into earth's atmosphere creating a brilliant show of the aurora borealis near Yellowknife, North West Territories on Thursday March 8, 2012. Yellowknife, which is situated directly under the auroral "oval", has some of the best northern lights viewing in the world. Truckers returning from the diamond mines 330 kilometers northeast enjoy the nighttime spectacle as they cruised down the ice road on Prosperous Lake. (AP Photo/The Canadian Press, Bill Braden)

The Northern Lights, also known as Aurora Borealis, occurs when energy particles from the sun interact with the earth’s magnetic field.
