Understanding the cause of auroras will help scientists solve the mystery around solar flares and what causes them and get a handle on the outer space weather.
I don't so much understand the geo-physics of why the solar winds slams into the earth's magnetic field in the magnetosphere — I'm simply enamoured by the spectacular shows, gallery here and here."

However, now I see a lot of people using it on their regular webpages. This could be a big problem if billions of different links are unreachable at a given time. What if a service starts sending a pop-up ad along with the redirect. What if the masked target links to a page with an exploit instead of linking to the new photos of Jessica Alba. Are services like tinyurl, urltea etc. taking the WWW towards a single point of failure? Is it a huge step backward? Or I'm just crying wolf here?"
