Northern Lights Probed


The US and Canada cooperate in a NASA rocket launch.
Scientists hope the $200 million US project will help them figure out what causes the substorms behind the shimmering northern lights, or aurora borealis, seen in northern skies.
Even growing up in northern Wisconsin I don't remember seeing the northern lights very often. It's like the cry of a loon. Unearthly and beautiful.
