Are Saturn's rings transparent?
The Cassini spacecraft that recently entered orbit around
has confirmed that some of
are more transparent than others.
Pictured above, Saturn's main
A, B, and C rings can be seen, top to bottom,
superposed against the gas giant planet.
Although the B-ring across the top is opaque, Saturn's cloud tops can be clearly seen through the lower C-ring.
The translucent nature of the
C-ring likely indicates that it is less densely populated with ring particles than the B-ring.
The above image was taken on July 30 while Cassini was over 7 million kilometers from Saturn.
