In practice, in northern Norway we are restricted to the period starting at the beginning of September and extending until the middle of April. ]]> 2017-01-13 21:44:27 UTC https://padlet.com/s74386/v5v9ag697x3s/wish/147160658 s74386 https://padlet.com/s74386/v5v9ag697x3s/wish/147161748 2017-01-13 21:54:16 UTC https://padlet.com/s74386/v5v9ag697x3s/wish/147161748 Chemistry of the Northern Lights s74386 https://padlet.com/s74386/v5v9ag697x3s/wish/147162133 The Northern Lights stem from when large numbers of electrically charged particles (Ions) at high speed stream in towards the Earth along its magnetic field and collide with the highest air particles. The air then lights up much like what happens in a fluorescent light tube. 
Different colours result due to this happening to certain gasses.
-The Yellow-Green Colour results from Oxygen
- Red results from Oxygen and Nitrogen together
- Violet and Blue results from Nitrogen]]> 2017-01-13 21:57:37 UTC https://padlet.com/s74386/v5v9ag697x3s/wish/147162133 s74386 https://padlet.com/s74386/v5v9ag697x3s/wish/147162530 2017-01-13 22:02:11 UTC https://padlet.com/s74386/v5v9ag697x3s/wish/147162530 5 Facts About The Northern lights https://padlet.com/s74386/v5v9ag697x3s/wish/147163909 1.
