NASA's Cassini spacecraft is monitoring the evolution of a mysterious feature in a large hydrocarbon sea on Saturn's moon Titan.

Compared to the age of the solar system -- about four-and-a-half billion years -- a couple of decades are next to nothing.

There is an ongoing drama in the Saturnian ring system that causes small moons to be born and then destroyed on time scales that are but an eyeblink in the history of the solar system.

The Cassini mission has revealed hundreds of lakes and seas spread across the north polar region of Saturn's moon Titan. These lakes are filled not with water but with hydrocarbons, a form of organic compound that is also found naturally on Earth and includes methane.

Saturn has a great many more moons than our planet - a whopping 62. A single moon, Titan, accounts for an overwhelming 96% of all the material orbit the planet, with a group of six other smaller moons dominating the rest. The other 55 small satellites whizzing around Saturn make up the tiny remainder along with the gas giant's famous rings.

Saturn's Polar Vortex and Rings

The Cassini spacecraft captures three magnificent sights at once: Saturn's north polar vortex and hexagon along with its expansive rings.

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.

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.

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 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 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.

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

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

NASA's Cassini spacecraft has captured its first-ever image of the pale blue ice-giant planet Uranus in the distance beyond Saturn's rings.

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

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

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

Looking Down at Saturn and Its Rings

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

60-Degree View of Saturn's Auroras

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

Stormy Saturn

Like a swirl from a paintbrush being dipped in water, this image from the Cassini orbiter shows the progress of a massive storm on Saturn.
