Mother and Daughter

From the Cassini page: In Greek mythology, Dione was the daughter of Tethys, so we should perhaps not be surprised to see the two eponymous moons together. In reality, the moons Tethys (660 miles or 1062 kilometers across) and Dione (698 miles or 1123 kilometers across) are not mother and daughter in any sense. They […]

Pluto Seen from Cassini

As New Horizons made its close approach, the Cassini spacecraft in orbit around Saturn was able to take this image showing Pluto. ┬Hard to tell which is Pluto? ┬Yes I agree, it is just about centered in the frame, click the image for an annotated version. The distance to Pluto at the time was 3. 9 […]

Titan and Saturn

While we wait for data from New Horizons, here is a lovely Cassini image of Saturn and Titan. This image was acquired from 1. 5 million km / 930,000 miles looking toward the anti-Saturn hemisphere of Titan. The image gives us a nice sense of scale, Titan at 5,150 km / 3,200 miles across (and the […]

Prometheus

This image from Cassini has to be one of the best shots of Prometheus and the interaction between it and the F ring. Check out the bump in the bottom third of the image. Very nice. JPL/NASA's description: Saturn's moon Prometheus, seen here looking suspiciously blade-like, is captured near some of its sculpting in the […]

Triple Crescents

his beautiful image from the Cassini spacecraft showing three of Saturn's moons as crescents is too good to pass up. The largest moon in the image is Titan (also Saturn's largest moon), notice how the crescent seems to wrap much around the moon more than the other two. Titan has an atmosphere that refracts light […]

Sinkholes on Titan: new study shows how hydrocarbon lakes may form by Earth-like erosion

Saturn's largest moon, Titan, has seas and lakes of liquid methane and ethane dotting its surface, but one question scientists have been trying to figure out is how the hollows in the ground, which hold the lakes, form to begin with. Now, a new study offers a solution: The depressions in the surface are formed... The post Sinkholes on Titan: new study shows how hydrocarbon lakes may form by Earth-like erosion appeared first on .
