Combined information from images taken by the Cassini and Galileo spacecraft indicates the new plume is about the same size -- nearly 400 kilometers or 250 miles high -- as a long-lived plume from Io's Pele volcano. Pele's plume and ring are also seen in the new images.

The images and further information about them are available online from NASA's Jet Propulsion Laboratory, Pasadena, Calif., at http://www.jpl.nasa.gov/pictures/jovianmoons , from the web sites of the Cassini Imaging Science team at the University of Arizona, Tucson, at http://ciclops.lpl.arizona.edu/ and from the University of Arizona's Planetary Image Research Laboratory, at http://pirlwww.lpl.arizona.edu/Galileo/Releases/ .

The new plume originates from a volcanic feature named Tvashtar Catena near Io's north pole. Scientists were astounded to discover so large a plume so near the pole, because all active plumes previously detected on Io have been over equatorial regions and no others have approached Pele's in size, said University of Arizona planetary scientist Dr. Alfred McEwen.

Galileo might pass right through the Tvashtar plume in August, if the plume persists until then. The spacecraft will be flying over that part of Io at an altitude of 200 kilometers (124 miles). Material in the plume is tenuous enough to present little risk to the spacecraft, and passing through it could give an opportunity to analyze the makeup of the plume, said Dr. Torrence Johnson, Galileo project scientist at JPL.

Cassini is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. JPL manages Cassini and Galileo for NASA's Office of Space Science, Washington, D.C. JPL is a division of the California Institute of Technology in Pasadena.
