7933270 story Colliding Auroras Produce Explosions of Light 30 Posted by Soulskill on Saturday December 19, 2009 @02:05PM from the pretty-pictures dept. elyons writes "Another neat discovery has come from the lab of Larry Lyons at UCLA. As reported earlier on Slashdot, Lyons' group studies the dynamics of auroras. Their most recent discovery reveals for the first time the sequence of events leading to dramatic space-weather disturbances. Using a network of cameras deployed around the Arctic in support of NASA's THEMIS mission, they recorded over 200 instances of auroras colliding, causing brilliant displays of northern lights (see time 8:22 for such an example)."
