Four views of Euboea Fluctus on Jupiter's moon Io showing changes seen on June 27th, 1996 by the Galileo spacecraft as compared to views seen by the Voyager spacecraft during the 1979 flybys. Clockwise from upper left is a Voyager 1 high resolution image, a Galileo enhanced color image, a Galileo image with simulated Voyager colors, and a Voyager 2 color image. North is to the top of the picture. The Galileo images show new diffuse deposits which have an unusual morphology for plume deposits. A diffuse yellowish deposit with a radius of 285 km extends to the northwest, whereas an intense reddish deposit marks a curving fallout margin to the southeast. This morphology may have resulted from the presence of a topographic obstruction to southeast of the vent. The Jet Propulsion Laboratory, Pasadena, CA manages the mission for NASA's Office of Space Science, Washington, DC.
