That's a nice picture. I've got the false colour composite of the same thing that makes it clearer, but it's in the other HDD which I've
disconnected from the PC. But from that picture you can see that the streak is actually behind the rings. In false colour image, you would've
instantly recognized it as Saturn itself, or rather, her outline. It looks that way because Cassini was capturing it at a very artistic angle, with
the rings in the foreground and Saturn in silhouette behind it. Truly beautiful shot.
The ones above are the so called "shepherd moons" that seem to maintain the shape of Saturn's rings through their small gravitational influences. I
forgot their names, but I'll try to look for it later, along with the colour composite.
Edit: Sorry my bad, the shepherd moons are within the rings, specifically within the gaps. Those things are either "transient clumps of dust" or
little "icy moonlets". In other words they've no idea exactly what it is. However they've provisionally named it
S/2004 S 3
and S/2004 S 6
. It's probably what
they say it is, but speculate away until they actually name it something more creative
Also, the known
shepherd moons and inner satellites:
Oh yeah, one more thing,
Not exactly the colour composite I mentioned, but you can see the similarity.
