Daphnis makes an impression

The wavemaker moon, Daphnis, is featured in this view, taken as NASA’s Cassini spacecraft made one of its ring-grazing passes over the outer edges of Saturn’s rings on Jan. 16, 2017. This is the closest…


Watercolor swirls on Saturn

Saturn’s north polar region displays its beautiful bands and swirls, which somewhat resemble the brushwork in a watercolor painting. Each latitudinal band represents air flowing at different speeds, and clouds at different heights, compared to…


Clouds of methane. Only on Titan.

NASA’s Cassini spacecraft watched clouds of methane moving across the far northern regions of Saturn’s largest moon, Titan, on Oct. 29­­­­ and 30, 2016. Several sets of clouds develop, move over the surface and fade…


A last, spectacular dip towards Saturn

After more than 12 years studying Saturn, its rings and moons, NASA’s Cassini spacecraft has entered the final year of its epic voyage. The conclusion of the historic scientific odyssey is planned for September 2017,…


Saturn’s rings and the bends

Saturn’s rings appear to bend as they pass behind the planet’s darkened limb due to refraction by Saturn’s upper atmosphere. The effect is the same as that seen in an earlier Cassini view (see PIA20491),…


Titan’s Vid Flumina flooded with liquid hydrocarbons

NASA’s Cassini spacecraft has found deep, steep-sided canyons on Saturn’s moon Titan that are flooded with liquid hydrocarbons. The finding represents the first direct evidence of the presence of liquid-filled channels on Titan, as well…


Enceladus, on thin ice

Of all the icy moons in the Solar System, Saturn’s moon Enceladus is probably the ‘hottest’ when measured for its potential to host life. Despite its distance from Earth, it may also be the easiest…
