CICLOPS: Cassini Imaging Central Laboratory for OPerationS

Io Caldera
[For trouble viewing the images/movies on this page, go here]
Voyager 1 took this narrow-angle camera image on 5 March 1979 from a distance of 69,000 kilometers. The feature shown is a volcanic caldera which may be actively spewing material into space (dark gray fuzz near the upper-right part of the caldera rim). In addition, very dark lava has flowed out of the fissure and spread on the floor of the caldera.

The Voyager Project is managed for NASA by the Jet Propulsion Laboratory, Pasadena, Calif.
