Io - Galileo
Two black and white global images of Jupiter's satellite Io
Two Galileo images of Jupiter's moon Io reveal some of the surface topography.
The active volcanic features such as Loki Patera, the horseshoe shaped feature
on the left side of the left image, appear to have relatively flat topography.
Other regions show evidence of higher relief. The dark butterfly-shaped spot
surrounded by the gray circle at the lower part of both images is the volcanic
area Pele. The surface has undergone substantial change since the Voyager
images were taken in 1979. The left image was taken from a range of 600,000 km
and the right from 563,000 km on Galileo's 7th orbit of Jupiter.
Features as small as about 12 km can be resolved in both images.
Io is 3640 km in diameter and north is up.
