Io - Galileo

Pele and Pilan Patera on Jupiter's satellite Io

This enhanced color Galileo image of Jupiter's moon Io shows the volcanic region known as Pele at the lower left surrounded by the red circle, and Pilan Patera, marked by the large 400 km diameter) gray circle to the upper right of Pele, superimposed on the red circle. This image was taken on 19 September 1997 on Galileo's 10th orbit of Jupiter. On the 9th orbit, five months prior to this, the large gray Pilan Patera circle was not present in images, but a 120 km high plume was erupting from this location at that time. The black, gray, and red areas appear to denote recent volcanic activity. Io is 3640 km in diameter and north is up. (Galileo, MRPS-94214)
