Photographs taken by NASA's Cassini probe in April 2013 show a bright arc about 750 miles long and 6 miles wide at the edge of Saturn's outermost ring. This arc was probably created by the gravity of a small, icy object nearby — possibly a newborn moon.

Saturn's moon Enceladus and the Jupiter satellite Europa both harbor subsurface seas and should be studied much more closer in the future, researchers say.
03 April 2014, 05:21 PM ET
Enceladus has an extensive water ocean under its icy crust, feeding water jets that emerge from near the south pole.
03 April 2014, 02:01 PM ET
Enceladus' ocean is about 6 miles deep and lies beneath a shell of ice 19 to 25 miles thick. Further, it's in direct contact with a rocky seafloor, theoretically making possible all kinds of complex chemical reactions.
03 April 2014, 02:00 PM ET
Using data from a close fly-by of the moon by NASA Cassini probe, researchers have suggested that there is something dense beneath 18 to 24 miles of ice. Liquid water is the most likely suspect, Sapienza Università scientist Luciano Less explains.

Scientists have made a stunning discovery in the outer realm of the solar system — an asteroid with its own set of rings that orbits the sun between Saturn and Uranus. The space rock is the first non-planetary object ever found to have its own ring system
26 March 2014, 02:01 PM ET
The asteroid Chariklo is surrounded by two rings similar to those around the brilliant planet Saturn. See images and artist views of the asteroid's strange rings in this Space.com gallery.
26 March 2014, 02:00 PM ET
New observations from telescopes in South America of asteroid (10199) Chariklo, as it passed in front of a distant star, have revealed rings. Astronomers believe the rings may be partially composed of water ice.
26 March 2014, 02:00 PM ET
Chariklo is the first asteroid discovered to have it's own ring system, and only the fifth body in the solar system. The largest of a class of asteroids known as Centaurs that orbit between Uranus and Saturn, Charriklo has two distinct, narrow rings.

New observations from NASA’s Saturn-orbiting Cassini spacecraft show what appear to be glints of sunlight bouncing off a wind-rippled lake on the moon Titan.
17 March 2014, 09:36 AM ET
On its final orbit In 2017, NASA's Cassini probe will fly between the inner edge of the D ring and the upper atmosphere of the gas giant. It will also fly though an Enceladus plume in the next few years.

A nearly full Rhea shines in the sunlight in this stunning space wallpaper taken in visible light with the Cassini spacecraft’s narrow-angle camera on Sept. 10, 2013. Rhea (949 miles, or 1,527 kilometers across) is Saturn's second largest moon.
10 March 2014, 08:00 AM ET
Researchers are developing flat, blanket-size landers that could be delivered en masse to worlds such as Mars or Jupiter's moon Europa. The approach could enable NASA to mount missions to places previously deemed too risky to explore, researchers say.
07 March 2014, 09:27 AM ET
Astronomers studying the dust and gas around bright star Beta Pictoris have discover a cloud of debris from collisions of icy comet-like bodies. It's possible that the comets are trapped in a small region by the gravity of a saturn-sized planet.
06 March 2014, 06:00 PM ET
A far-flung NASA space probe flying around Saturn zipped past the ringed planet's biggest moon for the 100th time. The Cassini spacecraft made its closest approach to the hazy moon Titan on Thursday.
06 March 2014, 07:30 AM ET
The space agency's Cassini probe snapped the photo in October, when it was 1.6 million miles from Saturn and 38 degrees below the ring plane. The planet's battered "Death Star" moon Mimas is visible as a pinprick of light at the bottom right.

A human would be able to take flight off the surface of Saturn's moon Titan by running in a wingsuit — but only if they were as fast as sprinter Usain Bolt, a group of physics students say.
