The Aurora Borealis brings people to Iceland from all over the world,
learn more about the stories and science behind it here.
The Northern Lights, or the aurora borealis, has amazed humanity for tens of thousands of years. Different cultures around the world came up with stories to explain this incredible natural phenomenon, for example in China the lights were thought to be a battle between good and bad dragons, or in Finland a fire fox ran across the sky so fast his tale sent sparks into the night.
In Norse mythology one legend suggests the lights are the reflection from the shields of the Valkyrie, fierce female warriors. The aurora was also thought to be the bifrost bridge, a glowing arc taking fallen warriors to Valhalla.
Now we understand a lot more about the science behind them but it doesn’t distract from our wonder, even in modern times we continue to make stories up about them, for instance in the best selling book ‘Northern Lights’ by Philip Pullman, where another world is visible through them. What story would you make up about them?
We spent a lot of time increasing our knowledge of the lights, and of astronomy too, but we feel the best, simplest description comes from our science heroes at NASA. They say;
The lights can display in all sorts of shapes, sometimes lighting up the sky for hours at a time. However the range of colours visible really excites us! Dr Anne Marie wrote this brilliant article last year. You can visit the original article here.
The Earth is not the only planet that has aurorae. Astronomers have photographed the aurora on Jupiter, Saturn, and Io, for example. However, the colors of the aurora are different on different planets because the atmosphere is different. The only requirement for a planet or moon to have an aurora is that it have an atmosphere that is bombarded by energetic particles. The Aurora will have an oval shape at both poles if the planet has a magnetic field. Planets without magnetic fields still have an Aurora, but it will be irregularly shaped.“
