Jupiter's Belt-Zone Boundary (Methane filter, 732 nm)

NOTE: This JPEG image is made available in order to share with the public the excitement of new discoveries being made via the NASA/JPL Galileo spacecraft. Galileo scientists are in the process of calibrating and validating this data. The full digital image necessary for scientific analysis will be released within one year of receipt of this orbit's last data.

This image is available only on the WWW; it is not available in hardcopy or other forms.

Mosaic of a belt-zone boundary near Jupiter's equator. The images that make up the four quadrants of this mosaic were taken within a few minutes of each other and show Jupiter's appearance at 732 nanometers (nm). Sunlight at 732 nm is weakly absorbed by atmospheric methane. This absoption lowers the total amount of scattered light detected by the Galileo spacecraft while enhancing the fraction that comes from higher in Jupiter's atmosphere, where less methane is present. The features of the lower visible cloud deck that are seen at 756 nm remain visible, but features in the higher, diffuse clouds are made more apparent. The most interesting features in this upper layer are the large holes in the lower half of the mosaic. These holes may permit the wind speeds of Jupiter's stratosphere to be measured for the first time.

The edge of the planet runs along the right side of the mosaic. North is at the top. The mosaic covers latitudes -13 to +3 degrees and is centered at longitude 280 degrees West. The smallest resolved features are tens of kilometers in size. These images were taken on November 5th, 1996, at a range of 1.2 million kilometers by the Solid State Imaging system aboard NASA's Galileo spacecraft.

Launched in October 1989, Galileo entered orbit around Jupiter on December 7, 1995. The spacecraft's mission is to conduct detailed studies of the giant planet, its largest moons and the Jovian magnetic environment. The Jet Propulsion Laboratory, Pasadena, CA manages the mission for NASA's Office of Space Science, Washington, DC.
