Titan is Drifting Away from Saturn Much Faster than We Thought

Recent research using data acquired by NASA’s Cassini spacecraft reveals that Titan is moving away from Saturn at a much faster rate than previously thought. How fast? Read on… “This result brings an important new piece of the puzzle for the highly-debated question of the age of the Saturn system and how its moons formed.”…

Enceladus Sprays its Ocean Into Space as it Awaits Our Return

Saturn’s 320-mile-wide moon Enceladus sprays its interior ocean into space in this picture, a color-composite made from images taken by NASA’s Cassini spacecraft on November 30, 2010 from the moon’s night side. The original images were captured in visible light filters and the result has been subjectively adjusted for contrast and saturation. South is pointed…

Saturn Seen Through Titan’s Hazy Atmosphere

Here’s a view of the upper limb of Saturn seen through the atmosphere of its largest moon Titan. It’s a color-composite of images captured by NASA’s Cassini spacecraft on March 31, 2005 as it passed just 7,500 kilometers (4,660 miles) from Titan. Saturn was 1.2 million kilometers (745,000 miles) away from Cassini at the time.

A Naked Titan Revealed by 13 Years of Cassini Data

Saturn’s largest moon Titan boasts the distinction of being the only moon in the solar system to have a thick atmosphere…so thick, in fact, that its surface is perpetually hidden from our view—but not from the view of the Cassini spacecraft’s infrared cameras! Cassini, now over ten months gone after its Sept. 2017 plunge into…

This Toxic Compound on Titan Could Support Life “Not as We Know It”

Saturn’s largest moon Titan is often called an analogy to early Earth, with its thick, chemical-rich atmosphere and widespread system of flowing rivers and north polar lakes. But located almost a billion miles away from the Sun, everything on Titan is shifted into a completely different—and frigid—level of existence from that found on Earth. With…

Saturn’s Moon Atlas is Literally a Flying Saucer

If you thought Pan resembled a UFO, Atlas is even more saucer-shaped! Slightly larger at about 19 miles across, Saturn’s moon Atlas was passed by NASA’s Cassini spacecraft on April 12, 2017, coming within about 9,000 miles. The images above are a collection of eight from Cassini’s closest approach. Like its smaller sibling Pan, Atlas…

Titan’s Cold Hydrocarbon Lakes Could Be Naturally Carbonated—Er, Nitrogenated

At the north pole of Saturn’s largest moon Titan lie the largest (and only known) bodies of surface liquid in the Solar System outside of Earth. But on Titan, where temperatures are regularly around negative 300ºF, the liquid isn’t water but rather methane and ethane: compounds which are found as gases here on Earth. Titan’s seas and lakes are…

Iapetus: Saturn’s Stained Moon

Saturn’s “yin-yang” moon Iapetus (pronounced eye-AH-pe-tus) is seen in this image, a color composite made from raw images acquired by Cassini’s narrow-angle camera on March 11, 2017. The color difference on Iapetus is due to a fine coating of dark material that falls onto its leading hemisphere, sent its way by the distant moon Phoebe traveling within the recently-discovered giant diffuse…

Our Best Ever Look at Pan, Saturn’s Little “UFO”

Behold the almighty Pan! Thanks to Cassini’s ring-grazing orbits we’ve just received the highest-resolution images ever of Pan—which, at only about 17 miles (27 km) across admittedly isn’t very “almighty” but its flying saucer-like shape is really quite fascinating! The raw images above were acquired by Cassini on March 7, 2017 and received on Earth on…
