NASA Keeps an Eye on Mount St. Helens
NASA scientists took these images of Mount St. Helens on Tuesday, Oct. 12. The image on the left combines visible and infrared data while the image on the right is infrared only. Bright red in the crater indicates hot spots. Blue on the left image indicates snow and the plume. Researchers used the MODIS/ASTER Airborne Simulator digital imaging system, a joint project between NASA's Ames Research Center and JPL, to acquire the infrared data. (Oct. 14)
