The northern lights (or aurora borealis) are widely known as one of Mother Nature's most beautiful works of art and deserving of an entry on anyone's adventure bucket list [1]. In order to catch the celestial light show in action, light gazers must travel above the Earth's magnetic poles to countries like Iceland, Greenland, Canada, and Norway — though there was a rare moment in 2020 when the northern lights were visible from the US [2], stretching from Washington to northern Iowa and across to upstate Maine. If international travel isn't in your immediate future — or you're still debating whether to put this natural wonder [3] on your bucket list — these breathtaking photos of the northern lights will make you want to book a trip as soon as you possibly can.
