A new ring of material found
New ring found in orbit of moon Atlas
9 September 2004
A new ring of material, called S/2004 1 R, has been seen in the orbit of Saturn's moon Atlas.
It is seen here marked in red in this view of the region between the edge of Saturn's A ring and the F ring.
The image was taken by the NASA/ESA/ASI Cassini-Huygens spacecraft wide-angle camera on 1 July 2004, just after the spacecraft had crossed the ring plane following Saturn orbit insertion.
The maximum radial resolution is approximately 7 kilometres per pixel. The region from the A ring to the F ring spans some 3500 kilometres. The image has been enhanced to show the presence of faint ring material just beyond the edge of the A ring and in the orbit of Atlas (indicated by the dotted red line).
The moon Prometheus (102 kilometres across) can be seen close to the F ring at the lower left of the image.
The Cassini-Huygens mission is a co-operative project of NASA, ESA and ASI, the Italian space agency.
