Since an image is worth more than a thousand words, I found a very well made video-clip which vulgarizes how northern (polar) lights are formed. If you still haven’t completely understood the whole aurora borealis (North pole) and aurora australis (South pole) process, the following video will make it clear once and for all!
You can also watch all sorts of other interesting and educative videos from the TED Education series which can be found here: Ted-Education Video Archive, or simply visit their website here: www.ted.com.
How are northern lights made? Watch the following video clip…
Cheers and 73s.
