NASA’s Cassini probe gazes across the icy rings of Saturn toward the icy moon Tethys, whose night side is illuminated by Saturnshine, or sunlight reflected by the planet.

Titan’s north pole in summertime

NASA’s Cassini spacecraft captured this view of bright methane clouds drifting in the summer skies of Saturn’s moon Titan, along with dark hydrocarbon lakes and seas clustered around the north pole.

Our home world framed by the rings of Saturn

A new view from NASA’s Cassini spacecraft shows planet Earth as a point of light between the icy rings of Saturn.

Cassini takes a close up look at Saturn’s moon Pandora

27 December 2016 Astronomy Now

NASA’s Cassini spacecraft has captured one of the highest-resolution views ever taken of Saturn’s moon Pandora.

Cassini beams back first images from new orbit

9 December 2016 Astronomy Now

NASA’s Cassini spacecraft has sent to Earth its first views of Saturn’s atmosphere since beginning the latest phase of its mission. The new images show scenes from high above Saturn’s northern hemisphere, including the planet’s intriguing hexagon-shaped jet stream.

It’s chaos at Saturn’s moon Hyperion

5 December 2016 Astronomy Now

The moon Hyperion tumbles as it orbits Saturn. Hyperion’s spin axis has a chaotic orientation in time, meaning that it is essentially impossible to predict how the moon will be spinning in the future.

The view from above

Saturn appears as a serene globe amid tranquil rings in this view from NASA’s Cassini spacecraft above the planet’s pole.

‘Impossible’ cloud found on Saturn’s moon Titan — again

22 September 2016 Astronomy Now

The puzzling appearance of an ice cloud seemingly out of thin air in the stratosphere of Titan has prompted NASA scientists to suggest that a different process than previously thought — possibly similar to one seen over Earth’s poles — could be forming clouds in the giant Saturnian moon’s hazy, brownish-orange atmosphere.

Saturn’s moon Rhea radiant in the sunlight

1 August 2016 Astronomy Now

In this image from NASA’s Cassini probe, Saturn’s moon Rhea appears dazzlingly bright in full sunlight. This is the signature of the water ice that forms most of the moon’s surface.

Moons of Saturn may be younger than the dinosaurs

25 March 2016 Astronomy Now

New research suggests that some of Saturn’s icy moons, as well as its famous rings, might be modern adornments. Their dramatic birth may have taken place a mere 100 million years ago. This would date the formation of the major moons of Saturn, with the exception of more distant Titan and Iapetus, to the relatively recent Cretaceous Period — the era of the dinosaurs.
