And it all starts in the nucleus! (Warning: any discussion of the nucleus excludes prokaryotes. The nucleus is a eukaryotic song and dance number, and don't you forget it.) Most eukaryotic cells have a nucleus throughout their entire life cycles, but there are a few notable exceptions.
The northern lights are strongest when an active area on the sunâs surface faces Earth. Spectacular displays of the northern lights thus occur at roughly 27-day intervals, the time it takes the sun to rotate once. October, February and March are the best months for seeing the aurora borealis.
This is why the best place to see the northern lights is in the arctic. Sometimes the Sun becomes very active and sends out even more energetic solar wind particles. This is when people in the UK can see the northern lights (although only if it is a clear night). People in Scotland have the best chance. Solar storms are sometimes reported on the news, or you can look at websites like Aurora Watch to find out when one might be on it's way.
