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.
On March 12, 2008, Cassini will swing by Saturn's moon Enceladus at an altitude of less than 100 kilometres at the point of closest approach.
The cloud of oxygen the Cassini spacecraft encountered as it first approached Saturn turned out to be a calling card from another celestial presence, the tiny moon Enceladus.
New observations from the Cassini spacecraft now at Saturn indicate the particles comprising one of its most prominent rings are trapped in ever-changing clusters of debris that are regularly torn apart and reassembled by gravitational forces from the planet.
Ultraviolet images of Saturn's rings indicates much of the system is filled with ice, as well as atoms derived from water. A cloud of oxygen extends millions of miles outward from Saturn, which may hint at collisions between unseen icy moons.
Ice particles are key players in the ever-changing panorama at Saturn, according to a new study led by a University of Colorado at Boulder professor using an instrument on the Cassini-Huygens spacecraft now at the ringed planet.
