Io - Galileo

Color image of Jupiter's satellite Io from 2.24 million km

Io
Galileo image of Jupiter's moon Io from 2.24 million km. The image is centered at approximately 5 N, 60 W in the Media Regio area. The white area at bottom center is eruptive center Masubi at 44S, 55W. The surface appears to have undergone substantial change since the Voyager images were taken in 1979. The bright regions on the eastern limb are more prominent in this image. Sulfur-rich compounds are responsible for much of the coloring, dark areas may be recent volcanic activity, and the bright areas may be sulfur dioxide frost. Io is 3640 km in diameter, the resolution of this image is about 23 km and north is up. (Galileo, P-47109)
