Cassini: 15 Years of Exploration

This video highlights sights and sounds from the journey of NASA's Cassini spacecraft. Cassini launched 15 years ago and has been exploring the Saturn system since 2004.

Dwarfed by Saturn

Saturn's moon Mimas appears near Saturn, dwarfed by its parent planet in this image. Mimas (246 miles, or 396 kilometers across) appears tiny compared to the storms clearly visible in far northern and southern hemispheres of Saturn.

Huge Burp At Saturn After Large Storm

NASA's Cassini spacecraft has tracked the aftermath of a rare massive storm on Saturn. Data reveal record-setting disturbances in the planet's upper atmosphere long after the visible signs of the storm abated, in addition to an indication the storm was more forceful than scientists previously thought.

The Unusual Moons of Saturn

Among the oddities of the outer solar system are the middle-sized moons of Saturn, a half-dozen icy bodies dwarfed by Saturn's massive moon Titan. According to a new model for the origin of the Saturn system, these middle-sized moons were spawned during giant impacts in which several major satellites merged to form Titan.

Bouncing on Titan

ESA's Huygens probe bounced, slid and wobbled its way to rest in the 10 seconds after touching down on Saturn's moon, Titan, in January 2005, a new analysis reveals. The findings provide novel insight into the nature of the moon's surface.

A Southern View of Saturn

The Cassini spacecraft takes an angled view toward Saturn, showing the southern reaches of the planet with the rings on a dramatic diagonal.

River Networks on Titan

For many years, Titan's thick, methane- and nitrogen-rich atmosphere kept astronomers from seeing what lies beneath. Saturn's largest moon appeared through telescopes as a hazy orange orb, in contrast to other heavily cratered moons in the solar system.

Winter Is Coming on Titan

False-color images from NASA's Cassini spacecraft show the development of a hood of high-altitude haze - which appears orange in this image -- forming over the south pole of Saturn's moon Titan.

Vortex Seen at Titan's South Pole

Images from NASA's Cassini spacecraft show a concentration of high-altitude haze and a vortex materializing at the south pole of Saturn's moon Titan, signs that the seasons are turning on Saturn's largest moon.

Subsurface Ocean on Titan

Data from NASA's Cassini spacecraft have revealed Saturn's moon Titan likely harbors a layer of liquid water under its ice shell.

Jet Streams Cross-Cut Saturn

Turbulent jet streams, regions where winds blow faster than in other places, churn east and west across Saturn. Scientists have been trying to understand for years the mechanism that drives these wavy structures in Saturn's atmosphere and the source from which the jets derive their energy.

Saturn's Rings and Ring Shadows

This image was taken on June 19, 2012 and received on Earth June 20, 2012. The camera was pointing toward Saturn at approximately 1,706,861 miles (2,746,927 kilometers) away, and the image was taken using the CB2 and CL2 filters.

Tropical Methane Lakes on Titan

NASA's Cassini spacecraft has spied long-standing methane lakes, or puddles, in the "tropics" of Saturn's moon Titan. One of the tropical lakes appears to be about half the size of Utah's Great Salt Lake, with a depth of at least 3 feet (1 meter).

Recent findings from NASA's Cassini mission reveal that Saturn's geyser moon Enceladus provides a special laboratory for watching unusual behavior of plasma, or hot ionized gas. In these recent findings, some Cassini scientists think they have observed "dusty plasma," a condition theorized but not previously observed on site, near Enceladus.

Saturn's moons Daphnis and Pan demonstrate their effects on the planet's rings in this view from the Cassini spacecraft.

Spectacular Image: Titan and Saturn

This image was taken on May 06, 2012 and received on Earth May 07, 2012. The camera was pointing toward Titan at approximately 475,131 miles (764,649 kilometers) away.

Data from NASA's Cassini mission reveal Saturn's moon Phoebe has more planet-like qualities than previously thought.

Saturn's giant moon Titan hides within a thick, smoggy atmosphere that's well-known to scientists as one of the most complex chemical environments in the solar system. It's a productive "factory" cranking out hydrocarbons that rain down on Titan's icy surface, cloaking it in soot and, with a brutally cold surface temperature of around minus 270 degrees Fahrenheit, forming lakes of liquid methane and ethane.

This Week's Photo of Titan

This image was taken on April 08, 2012 and received on Earth April 09, 2012. The camera was pointing toward Titan at approximately 1,810,102 kilometers away, and the image was taken using the CL1 and CB3 filters. This image has not been validated or calibrated.

In January 2005 the Huygens probe landed on Titan, the biggest of Saturn's moons. It was the first earth-born object to land in the outer solar system. Now, new discoveries by the Cassini-Huygens mission could change our assumptions about the presence of life in the Solar System.
