Many eyes on Io
On the left, the LORRI camera captured a highly detailed, black-and-white view of the sunlit crescent, showing surface structures as well as the gigantic plume of Tvashtar erupting near the north pole. At upper right, the MVIC near-infrared imaging spectrometer sees coloration due to compositional variations across the sunlit crescent, and also sees the incandescent glow of the throat of Tvashtar. At lower right, the LEISA spectrometer, which sees longer infrared wavelengths than MVIC, captured the glow of Tvashtar as well as a great many more volcanic centers on Io's night side. Further analysis of LEISA images will yield the temperatures of these volcanic centers.
