Pele and Loki on Jupiter's satellite Io

Io
Galileo image of Jupiter's moon Io showing the volcanic centers Pele and Loki Patera. Pele is at the center of the large red circle in th elower part of the image. Pele has exibited the largest volcanic plume on Io, which has deposted the material forming the red ring. Loki Patera is the black horseshoe-shaped feature near the terminator towards the upper left. Io is the most volcanically active body in the solar system. The varied colors on the surface are due to sulfur rich compounds. Features as small as 12 km can be resolved in this image. Io is 3640 km in diameter and north is up. (Galileo, P-49758)
