Io on Galileo's E6 orbit
Io on Galileo's E6 orbit This view of the anti-Jovian hemisphere of Io was captured by Galileo on February 20, 1997, on its "E6" orbit. The volcano named Prometheus, which has been erupting continuously since Voyager flew past, is in the center of the disk, with a curl of black lava exiting to its right.
