Key matters are the interaction of charged solar ions with the Earth's magnetosphere. The article is a cover of Tuesday's earlier AP story (http://news.yahoo.com/s/ap/20071211/ap_on_sc/northern_lights). Apparently, it was unclear before now exactly how it all worked. Anyone else completely baffled by this? I could swear I read an entire book on the subject when I was 8, with detailed information regarding the process. Even Wikipedia seems pretty sure about the issue. Is there actual new information, or has the newsmedia botched yet another science discovery?"
