Aurora boreale 10 - 2003 - Aurora borealis 10 - 2003 - Aurora boreale observed in Alaska, October 31, 2003. Two huge solar eruptions are responsible for this aurora widely observed on Earth. This image is taken on the morning of October 31, 2003. Two massive solar flares, among the most powerful ever recorded, were responsible for beautiful auroras seen from much of the world. The huge events actually stripped layers from the Earth's outer atmosphere and it took several months to return to normal. Fortunately for us on Earth this atmosphere protects us from the intense particle radiation. An astronaut on a space - walk would not fare so well and would soon be dead due to the exposure to this kind of radiation
