Saturn's Rings Have an Atmosphere of their Own

Summary - (Aug 18, 2005) Saturn's rings are separate from the planet they
circle, and then even have an atmosphere of their own. During several
flybys, Cassini has been able to detect very small amounts of molecular
oxygen floating around the rings. Molecules of water are broken apart by
ultraviolet light from the Sun; the hydrogen and some of the oxygen is lost
into space, and some of the oxygen is frozen back into the rings. But
there's enough of a cloud of these atoms around the rings that this process
must be ongoing and kept in a continual balance.

Can atoms actually be "lost in space"?

No, all energy is indestructible, " Lost in Space " was a 60's
entertainment sci fi TV show, with reruns still showing on cable.
Universe energy can be transformed but never lost.

carry on,

Hi nightbat The inferred rays of the Sun will destroy Saturn's rings in
about 100 million years. This tells us that these rings are fairly
new. this answers the question Why no water molecules on Mars surface.
The ice rocks that make up Saturn's rings don't decay,or evaporate.
Reality is the two gases are split apart by inferred photons. Water in
the form of ice makes this process easier. Still a theory could be
worked out making Saturn's rings regularly replaced by comets time after
time. Bert
