Aurora borealis

Aurora Borealis

Canada's northern latitude makes it an ideal place to catch the aurora borealis. Created when charged particles from the sun collide with Earth's upper atmosphere, auroras vary in color from red to green to blue and vary in shape from drapes to arcs to bands.

“Into the bowl of the midnight sky / Violet, amber and rose…” Famed gold rush poet, Robert Service, was inspired by the North and enthralled by the northern lights.

Those same mesmerizing skies arrive each fall as darkness returns to Yukon nights. You might first see a hint of neon colour, then a jagged burst of green, and soon you're transfixed by shimmering aurora borealis. Dependent on auroral activity and clear skies, every appearance of the northern lights is special.
