Geysers on Enceladus

This artist's rendering shows a cross-section of the ice shell immediately beneath one of Enceladus' geyser-active fractures, illustrating the physical and thermal structure and the processes ongoing below and at the surface.

Saturn Imitates the Moon

Saturn appears to Cassini's cameras as a thin, sunlit crescent in this unearthly view. Citizens of Earth, being so much closer to the Sun than Saturn, never get to enjoy a view of Saturn like this without the aid of our robot envoys.

The Moon Eclipses Saturn

The Moon Eclipses Saturn

What happened to half of Saturn? Nothing other than Earth's Moon getting in the way. As pictured above on the far right, Saturn is partly eclipsed by a dark edge of a Moon itself only partly illuminated by the Sun.


Ocean on Saturn's Moon Titan Could be as Salty as the Dead Sea

Ocean on Saturn's Moon Titan Could be as Salty as the Dead Sea

Scientists analyzing data from NASA's Cassini mission have firm evidence the ocean inside Saturn's largest moon, Titan, might be as salty as the Earth's Dead Sea.


Cassini Names Final Mission Phase Its 'Grand Finale'

Cassini Names Final Mission Phase Its 'Grand Finale'

With input from more than 2,000 members of the public, team members on NASA's Cassini mission to Saturn have chosen a name for the final phase of the mission: the Cassini Grand Finale.


Titan's Building Blocks Might Pre-date Saturn

Titan's Building Blocks Might Pre-date Saturn

A combined NASA and ESA-funded study has found firm evidence that nitrogen in the atmosphere of Saturn's moon Titan originated in conditions similar to the cold birthplace of the most ancient comets from the Oort cloud. The finding rules out the possibility that Titan's building blocks formed within the warm disk of material thought to have surrounded the infant planet Saturn during its formation.


Prometheus Interacts With Saturn's F Ring

Prometheus Interacts With Saturn's F Ring

Prometheus is caught in the act of creating gores and streamers in the F ring. Scientists believe that Prometheus and its partner-moon Pandora are responsible for much of the structure in the F ring.


Titan's Polar Vortex

Titan's Polar Vortex

Titan's polar vortex stands illuminated where all else is in shadow. Scientists deduce that the vortex must extend higher into Titan's atmosphere than the surrounding clouds because it is still lit in images like this.


Sunsets on Titan Reveal the Complexity of Hazy Exoplanets

Sunsets on Titan Reveal the Complexity of Hazy Exoplanets

Scientists working with data from NASA's Cassini mission have developed a new way to understand the atmospheres of exoplanets by using Saturn's smog-enshrouded moon Titan as a stand-in.


Evidence That Saturn's Collapsing Magnetic Tail Causes Auroras

Evidence That Saturn's Collapsing Magnetic Tail Causes Auroras

University of Leicester researchers have captured stunning images of Saturn's auroras as the planet's magnetic field is battered by charged particles from the Sun.


Saturn's Rainbow Rings

Saturn's Rainbow Rings

This colourful cosmic rainbow portrays a section of Saturn's beautiful rings, four centuries after they were discovered by Galileo Galilei.


Birth of New Moon for Saturn?

Birth of New Moon for Saturn?

NASA's Cassini spacecraft has documented the formation of a small icy object within the rings of Saturn thatmay be a new moon, and may also provide clues to the formation of the planet's known moons.


Help Name Cassini's New Mission

Help Name Cassini's New Mission Video in Story

As NASA's Cassini mission approaches its 10th anniversary at Saturn, its team members back here on Earth are already looking ahead to an upcoming phase.


Enceladus Has An Underground Sea

Enceladus Has An Underground Sea

Saturn's icy moon Enceladus has an underground sea of liquid water, according to the international Cassini spacecraft.

This image of Saturn and its rings was taken on February 06, 2014 by Cassini and received on Earth February 07, 2014.


The Dance of Saturn's Auroras

The Dance of Saturn's Auroras Video in Story

Ultraviolet and infrared images from NASA's Cassini spacecraft and Hubble Space Telescope show active and quiet auroras at Saturn's north and south poles.


60-Degree View of Saturn's Auroras

60-Degree View of Saturn's Auroras Video in Story

NASA trained several pairs of eyes on Saturn as the planet put on a dancing light show at its poles.


Looking Down at Saturn's North Pole

Looking Down at Saturn's North Pole

Just as Saturn's famous hexagonal shaped jet stream encircles the planet's north pole, the rings encircle the planet, as seen from Cassini's position high above.
