This image of the northern polar region of Saturn, captured by Cassini, shows both the aurora and underlying atmosphere seen at two different wavelengths of infrared light.

The hexagon is similar to Earth’s polar vortex, which has winds blowing in a circular pattern around the polar region. On Saturn, the vortex has a hexagonal rather than circular shape.

(PhysOrg.com) -- This view from NASA's Cassini spacecraft looks toward the south polar region of Saturn's largest moon, Titan, and shows a depression within the moon's orange and blue haze layers ...

Heat output from the south polar region of Saturn's moon Enceladus is much greater than was previously thought possible, according to a new analysis of data collected by NASA's Cassini spacecraft.

A team of scientistsfrom MIT has put forward a theory that would explain the presence ofenormous polar cyclones present on the gas giant Saturn. Thecyclones, first discovered by the Cassini ...

The bizarre vortex spinning at Saturn's north pole takes center stage in a newly released photo by NASA's Cassini spacecraft.

Many smaller storms dot the north polar region and Saturn's signature rings, which appear to disappear on account of Saturn's shadow, put in an appearance in the background.

But sometimes they move with the rotation of Saturn, mimicking what happens at Jupiter. When an aurora at Saturn brightens, its diameter around the polar region shrinks. At Earth, it expands.

The Cassini spacecraft has captured a stunningly detailed view of the "dark eye" of Saturn's vast south polar vortex, a feature so large that it could comfortably swallow planet Earth.

This Nov. 12, 2008 image of the northern polar region of Saturn shows both the aurora and underlying atmosphere, seen at two different wavelengths of infrared light by Cassini.
