New observations by NASA's Cassini spacecraft indicate the rings of
Saturn, once thought to have formed during the age of the dinosaurs,
instead may have been created roughly 4.5 billion years ago when the solar
system was still under construction.

Scientists have gotten their best "look" ever at the invisible ring of
energetic ions trapped in Saturn's giant magnetic field, finding that it
is asymmetric and dynamic, unlike similar rings that appear around Earth.

HOT CYCLONES CHURN AT BOTH ENDS OF SATURN
-----------------------------------------
Despite more than a decade of winter darkness, Saturn's north pole is home
to an unexpected hot spot remarkably similar to one at the planet's sunny
south pole. The source of its heat is a mystery. Now, the first detailed
views of the gas giant's high latitudes from the Cassini spacecraft reveal
a matched set of hot cyclonic vortices, one at each pole.

Cassini finds mingling moons may share a dark past
 
19 February 2008   Despite the incredible diversity of Saturn's icy moons, theirs is a story of great interaction. Some are pock-marked, some seemingly dirty, others pristine, one spongy, one two-faced, some still spewing with activity and some seeming to be captured from the far reaches of the solar system. Yet many of them have a common thread - black 'stuff' coating their surfaces.

Saturn's moon Rhea may also have rings

7 March 2008
The Cassini spacecraft has found evidence of material orbiting Rhea, Saturn's second largest moon. This is the first time rings may have been found around a moon.
