It’s been a while since I posted an image of my favorite moon of Saturn, but while looking through some recent raw images returned by the Cassini spacecraft I spotted it: Daphnis, the little sculptor shepherd moon!

Titan: Saturn’s Glow-In-The-Dark Moon
Titan just never ceases to amaze. Saturn’s largest moon, it’s wrapped in a complex, multi-layered nitrogen-and-methane atmosphere ten times thicker than Earth’s. It has seasons and weather, as evidenced by the occasional formation of large bright clouds and, more recently, an area of open-cell convection forming over its south pole. Titan even boasts the distinction…
Once you realize what this Cassini image is showing, you’ll love it.
Go ahead, take a look. Let it sink in…..waaaait for it…… there. I told you. Still wondering what it is you’re looking at? That’s ok, you’ll love it even after I tell you.
Cassini Peeks at Titan’s Southern Vortex
A color-composite image of Titan shows Saturn’s largest moon in true color, including its recently-discovered southern vortex forming above its south pole. The image was assembled from three raw images acquired on August 28 by NASA’s Cassini spacecraft in red, green and blue visible light color channels. The background was extended in size to better…
Dione in Color
Although made mostly of ice and rock, Saturn’s moon Dione (pronounced DEE-oh-nee) does have some color to it — although mostly chilly hues of steel blue, as seen in this color-composite made from raw images acquired by Cassini on July 23.
Titan’s Beautiful, Boiling Southern Vortex
Thanks to Cassini’s new vantage point granted by its inclined orbit researchers have gotten a new look at the south pole of Titan, Saturn’s largest moon. What they’ve recently discovered is a swirling vortex of gas forming over the moon’s pole, likely the result of the approach of winter on Titan’s southern hemisphere. Read the…
The Colors of Titan and Saturn
The pumpkin-orange colors of Titan’s thick clouds appear in stark contrast in front of the limb of Saturn, which appears quite blue along its sunlit limb due to Rayleigh scattering, the same process that makes the sky look blue here on Earth. The image here is a color composite made from three separate raw images…
More Evidence for Titan’s Underground Ocean
As Titan travels around Saturn during its 16-day elliptical orbits, it gets rhythmically squeezed by the gravitational pull of the giant planet — an effect known as tidal flexing. Now, if this cloud-covered moon were mostly composed of rock, the flexing would be in the neighborhood of around 3 feet (1 meter.) But based on measurements…
Up and Over the Rings – Atlas and Pandora
Cassini’s at it again! After its last flyby of Titan the spacecraft changed course, heading up and away from Saturn’s equatorial plane at an angle that will allow it to better study the rings and the planet’s polar regions. This raw image, captured on May 23, shows Cassini’s view as it heads upwards. It shows…
The Curious Central Peaks of Iapetus
The curious, 20-km tall central ridge of Iapetus, a.k.a. the Voyager Mountains Saturn’s 914-mile (1471-km) -wide Iapetus (pronounced eye-AH-pe-tus) has a particularly curious feature: a chain of 20-kilometer (12-mile) high mountains encircling the moon’s equator. On the anti-Saturnian side of Iapetus, the ridge appears to break up, forming distinct, partially bright mountains. The Voyager I…
Take a Look at Titan!
Here’s a great shot of Titan and Saturn acquired by Cassini on May 6, 2012 just after a pass by the haze-covered moon. It’s a color-composite made from images taken in Cassini’s red, green and blue color channels, and the resulting image was color adjusted a bit to appear more “Saturny”.
Mighty Melanthius
The 662-mile-wide Tethys is one of the most heavily cratered worlds in the solar system, tied with sister moons Rhea and Dione. In this recent raw image captured by Cassini on April 14, we can see some of the moon’s larger craters, including Melanthius with its enormous central peak.
