The Northern Lights, or Aurora Borealis, is nature’s own spectacular fireworks show on display in the colder places on Earth. It’s definitely worth a view, judging from these pictures. For those of you who do not like the cold we recommend the Southern Lights; and wherever you go we recommend you bring a camera.
