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.
A Golden Oldie
Time to go “all way back” to 2006! In this Cassini image beautifully color calibrated by Gordan Ugarkovic we see the moon Mimas tucked into the shadow of Saturn’s rings. Nicknamed the “Death Star” moon, Mimas features a large crater with a sharp central peak, giving it a striking resemblance to the infamous sci-fi space…
The Color of Rhea
If someone were to ask you today what the most heavily-cratered world in the Solar System is, you can’t go wrong with saying “why, Rhea of course!” (I don’t know why someone would ask you that, but if anyone does you can now consider yourself well-prepared.) 🙂
Enceladus Sprays Its Secrets To Cassini
Enceladus, Saturn’s 318-mile-wide moon that’s become famous for its ice-spraying southern jets, is on astronomers’ short list of places in our own solar system where extraterrestrial life could be hiding — and on March 27, NASA’s Cassini spacecraft was in just the right place to try and sniff it out. Why does Cassini team director…
A Little Pas de Deux: Tethys and Dione
Saturn’s moon Tethys, its giant Odysseus crater in plain view, passes in front of of the slightly darker Dione in this animation made from several raw images acquired by Cassini earlier this month. Pretty cool!
Pretty as a Picture: Enceladus and Titan
Little Enceladus and enormous Titan are seen on either side of Saturn’s rings in this image, a color-composite I made from raw images acquired by Cassini on March 12, 2012. Read more here.
Rugged Rhea
Here’s a color-composite image of Rhea, made from raw images acquired by Cassini during a flyby on March 10, 2012. The color is derived from images taken in infrared, green and ultraviolet light.
Titan. In color.
On Jan. 30, the Cassini spacecraft executed a flyby maneuver of Titan, Saturn’s largest moon, passing within 19,340 miles (31,130 km) of its surface. This color composite image of the cloud-covered moon was created by combining raw data acquired with Cassini’s Imaging Science System (ISS) in red, green, blue and clear color channels. The result…
From the LITD Archives: Eclipsing Mimas
Originally published on May 16, 2009. LITD is almost 3 years old! This animation, made from a series of 8 raw images taken by Cassini on May 14, shows Saturn’s moon Mimas being eclipsed by another object…..a neighboring moon, perhaps? It’s not mentioned, but it definitely seems to be something of similar size, and round….
