Saturn's G-ring Target Name:   Saturn Spacecraft:   Voyager 2 Produced by:   Calvin J. Hamilton Copyright:  © 2002 Calvin J. Hamilton Date Taken:   26 August 1981 Date Released:  25 February 2002 (Publisher Permission Request) Related Documents Saturn's Magnificent Rings Saturn Download Options Name Type Width x Height Size gring1.jpg JPEG 601 x 653 19K gring1.jpg JPEG 1803 x 1960 81K gring1.tif TIFF 1803 x 1960 775K Saturn's G ring was discovered by Voyager 1 in November 1980 and imaged again by Voyger 2 on August 26, 1981 from a range of about 175,000 kilometers. The 8000 kilometer wide G-ring is extreamly tenuous and difficult to see. It is more neutral in color than the E-ring. In this image the A-ring on the right hand side has been washed out due to the long exposure required to bring out the G-ring. Significant image processing was used to isolate the G-ring from the background noise. This included carefully flattening the image intensity across the image plane with low and high pass filtering applied to the G-ring region.
