With bonus rings.

Another great picture from the Cassini Probe, taken from Astronomy Picture of the Day for 4/4/2021.

The most obvious moon is the bright Dione, hovering on the centre of the frame, with shadowy but much larger Titan in the background. Titan is the tenth largest object in the Solar System bigger than the planet Mercury.

To the extreme right of the rings is Pandora, a moon which shepherds Saturn’s F ring.

Just in the gap in the rings (the Encke gap) is Pan, only 35 kilometres across but which keeps the gap free of ring particles.

I love photographs like this.

From Astronomy Picture of the Day for 17/10/19.

Janus, Pandora, Enceladus, Mimas and Rhea, not to mention an arc of Saturn’s rings almost end-on. Taken by the Cassini probe.

From Astronomy Picture of the Day, for 15/2/18, another wonderful photograph from the Cassini mission to Saturn, this one showing the moon Enceladus outgassing plumes of ice.

At bottom right of middle just below the edge-on rings of Saturn can be seen the small moon Pandora.

Astronomy Picture of the Day for 26/10/11 was this stunning view of four of Saturn’s moons, one (Dione) pictured in relief against the background of another (Titan.)

Saturn’s rings jut into the picture and the shepherd moon, Pandora, can be seen as an extended bright blur beyond their tips. In the ring gap (the Encke Gap) you can just make out an inner shepherd moon, Pan, whose presence keeps the gap free of ice particles.

This sort of image is just brilliant. It gives me the famous “sense of wonder” associated with Science Fiction.
