Huge storm on Saturn

"This new storm is a completely different kind of beast compared to anything we saw on Saturn previously with Cassini. The fact that such outbursts are episodic and keep happening on Saturn every 20 to 30 years or so is telling us something about deep inside the planet, but we have yet to figure out what it is."

Scientists discover massive ring around Saturn

Scientists at NASA have discovered a nearly invisible ring around Saturn -- one so large that it would take 1 billion Earths to fill it.

The ring's orbit is tilted 27 degrees from the planet's main ring plane. The bulk of it starts about 3.7 million miles (6 million km) away from the planet and extends outward another 7.4 million miles (12 million km).

Mysterious hexagon spotted on Saturn

A strange hexagon shape over the north pole of Saturn was first spotted by the two Voyager spacecraft has been revisited by the Cassini probe. The 26 years between sightings indicate it is likely a permanent feature on Saturn, according to NASA scientists. In fact, Cassini found a second hexagon, significantly darker than the orginal. This is the first time the feature has been captured on one image.

On NASA's Web site, Kevin Baines, atmospheric expert and member of Cassini's visual and infrared mapping spectrometer team at NASA's Jet Propulsion Laboratory, said, "Saturn's thick atmosphere where circularly-shaped waves and convective cells dominate is perhaps the last place you'd expect to see such a six-sided geometric figure, yet there it is."

This image was captured at night by Cassini's infrared mapping spectrometer. The red color indicates heat generated from the planet's interior.
