“June 20, 2007 Pasadena, California - A year ago on July 23, 2006, the Cassini-Huygens spacecraft orbiting Saturn took a series of images of the rings that were received back on earth at the Jet Propulsion Laboratory (JPL) in Pasadena, California, on July 24, 2006.
The four images are numbered in sequence and I have arranged them in order below. You can clearly see the light changes position from one ring band in image W00016503 to a further ring band in image W00016506. The NASA/JPL text states that the images were "taken on July 23, 2006, and received on Earth July 24, 2006. The camera was pointing toward SATURN-RINGS at approximately 209,976 kilometers (130,500 miles) away, and the image was taken using the CL1 and CL2 filters. This image has not been validated or calibrated. A validated/calibrated image will be archived with the NASA Planetary Data System in 2007."”
