The Aurora flares up when charged particles from the sun interact with the Earth’s outer atmosphere. The colours of the Aurora vary based on what layer of the atmosphere is being “excited.” The most common colour is an eerie green and yellow glow, caused by the excitement of oxygen atoms about 120 kilometres above the Earth’s surface. Depending on the element, the Northern Lights can come to life with reds, blues, and purples. Each time the show is different, but the effect is always the same – wonder, awe, and lasting memories.
Being the home of the best Northern Lights in the world is a pretty bold claim, but we’ve got the facts to prove it. Here’s why we’re sure you’ll agree that the NWT has the world’s best Aurora.
