The "Emakong" Patera (HR)

Caption NASA originale:"Clues about how lava spreads great distances on Jupiter's volcanic moon Io come from HR views taken by NASA's Galileo spacecraft of a lava channel flowing out of Emakong Patera near Io's equator.
The lava channel is dark and runs to the right from the dark patera, or large depression, at the left of this mosaic. The 1999 images showed a dark channel though which molten material once fed a broad, bright lava flow that extended for hundreds of Km".
