A network of cameras deployed around the Arctic to understand the trigger mechanism for the beautiful light display called the aurora borealis – also known as the Northern Lights – has discovered that sometimes the vast curtains of aurora borealis collide, producing a stunning outburst. The reason no one on Earth has ever noticed these collisions before is that they occur on such a vast scale it takes a network of sensitive cameras spread across thousands of miles to get the whole picture.
