RED AIRGLOW OVER THE ATACAMA DESERT: Last night, the normally dark skies of Chile's Atacama Desert lit up with rippling bands of red light. It looked like the aurora borealis, but it was not. A photographer recorded the unusual apparition of red airglow, so bright that it outshined parts of the Milky Way. Visit today's edition of Spaceweather.com for photos and an explanation of this phenomenon.
