Saturn's rings rain charged water particles down onto the gas giant's atmosphere, causing measurable changes in the planet's ionosphere. ->

The Cassini science team has released humanity's first picture of what sunlight glinting off a lake looks like on another world. This is Titan, Saturn's largest moon, which has lakes of liquid hydrocarbons on its surface. NASA says its scientists have been looking for the glint of light o...

On Saturday, the Cassini Solstice mission flew past the Saturnian moon Enceladus at a breakneck speed of 17,000 mph and an altitude of only 62 miles!

The Cassini Solstice mission passed by the small Saturnian moon Hyperion over the weekend, soaring as close as 24,000 kilometers (15,000 miles) from the tumbling moon's cratered face.

NASA's Saturn-orbiting Cassini spacecraft this month made its closest pass yet of the odd, eyeball-shaped moon Mimas, which bears the scar of a massive, violent impact from its past. The 88-mile wide Herschel crater is about one-third the diameter of Mimas, an inner moon of Saturn measuring about 2...

A NASA probe sends back its summer trip photos -- of Saturn's moon.

Saturn's moon Enceladus has turned out to be quite the overachiever among moons in our solar system -- it pours rain onto Saturn.

Curious how planets can form from disks of gas and dust? Well, the rings of Saturn are serving scientists as a living laboratory to better understand the process.
