A Portion of Saturn's B Ring
A portion of Saturn's B-ring. Taken from http://antwrp.gsfc.nasa.gov/apod/ap071024.html. Credits of this photo include NASA, and as the APOD website says, "NASA images are in the public domain" (see http://antwrp.gsfc.nasa.gov/apod/lib/about_apod.html). I highly recommend the Astronomy Picture of the Day.
