Astronomers May Have Spotted Waves On Titan's Seas

Other than Earth, Titan is the only celestial object in the solar system capable of fostering stable liquids on the surface. But now, after years of searching, scientists may have detected waves rippling on its seas — which, if confirmed, would be the first discovery of its kind. » 3/18/14 6:40am 3/18/14 6:40am

NASA captures unprecedented 360-degree views of Saturn's auroras

Like Earth, Saturn features active and radiant auroras at its poles. To date, our impressions of these fantastic features have been fleeting and sporadic at best. But now, using several pairs of telescopic eyes, NASA has caught its best glimpse yet of these massive, swirling auroras. » 2/12/14 1:20pm 2/12/14 1:20pm

What is Cassini's most amazing discovery?

NASA's Cassini probe has been exploring the Saturn system for almost a decade. In that time, it has fundamentally changed the way we look at the Ringed Planet and its many moons – not to mention the rest of our solar system. But which of its observations rank among Cassini's greatest contributions to science? » 1/11/14 10:00am 1/11/14 10:00am

Saturn does its best to imitate a Christmas ornament

Assuming you read the headline, I'm probably not going to be able to convince you that this image is an extreme, shadowy close-up of a Christmas bauble. But it can still be hard to believe that these boldly colored, oddly perfect circles and hexagons can really be found in Saturn's northern hemisphere. » 12/24/13 6:40am 12/24/13 6:40am

Putting an age on Saturn's ring system

When, exactly, Saturn acquired its iconic ring-system is a longstanding point of debate among planetary scientists. Some maintain the structures formed relatively recently, while others argue they formed long ago. Now, newly collected data suggest the rings likely formed 4.4-billion years ago, lending strong support to … » 12/13/13 9:30am 12/13/13 9:30am

New Hi-Res Footage Shows Saturn's Mysterious Hexagon Like Never Before

You're looking at a newly released 8-frame movie of Saturn's enigmatic "hexagon." It is the highest-resolution footage ever acquired of the massive six-sided maelstrom atop the ringed planet's north pole, and boy howdy is it gorgeous. » 12/05/13 7:20am 12/05/13 7:20am

This stunning view of Saturn will restore your sense of wonder

Not since the release of this beautifully backlit view of Saturn have we found ourselves so arrested by an image of the ringed planet. Which, for a celestial body as consistently photogenic as Saturn, is truly saying something. » 10/17/13 12:40pm 10/17/13 12:40pm

Humanity waves at Saturn as Cassini snaps historic pic

Late last month, the Cassini spacecraft captured a remarkable photograph of the Earth and Moon as seen from Saturn. The event coincided with a project called "The Day The Earth Smiled" in which participants from 40 countries took photos of themselves waving at the ringed planet. The results have now been assembled into… » 8/22/13 6:30am 8/22/13 6:30am

Behold the Earth and Moon – as seen from Saturn

Last Friday, people the world over had their first chance ever to smile for a picture of Earth taken from outer space, when NASA's Cassini orbiter photographed our moon and planet from almost one-billion miles away.

Jupiter's hot spots reveal a tantalizing glimpse into the gas giant's…

As a gas planet, it's not exactly surprising that Jupiter is famous for its storms and clouds—indeed, Jupiter's most famous feature, the Great Red Spot, is a storm that's lasted perhaps 400 years and is at least twice the size of Earth. By those standards, the rare breaks in Jupiter's swirling cover are tiny, but they … » 3/17/13 3:02pm 3/17/13 3:02pm

NASA has found a free particle accelerator floating in space

In early 2007, NASA's Cassini spacecraft observed something extraordinary around Saturn. An unusually strong blast of solar wind sent subatomic particles crashing into the ringed planet's magnetic field, giving rise to perhaps the most tremendous shock wave ever observed emanating from the planet. But newly announced… » 2/27/13 9:00am 2/27/13 9:00am
