There are some gorgeous crescent saturn images coming down in the raws at the moment.

You can really see how oblate saturn is.

Yep...some lucky tourists will pay the big bucks to see that in person around the year 2300 or so... smile.gif

A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

The oblation is what struck me, too.

What are we seeing in the images that alternate with with crescent shots? I assume it's the cloud tops, and the black band at the bottom is the shadow of the rings or the rings themselves.

Definitely.

Meanwhile, we'll have to be grateful for whoever at JPL takes the trouble to post the feeds.

Yes, whoever does that is an unsung hero.

Notice the tiny black dot in the upper left of the crescent? In a similar image released last week
Ciclops such a dot was identified as Epimetheus. I wonder if that's what it is here or perhaps another satellite?

What is that little white dot at the bottom of the image?


--------------------
"After having some business dealings with men, I am occasionally chagrined,
and feel as if I had done some wrong, and it is hard to forget the ugly circumstance.
I see that such intercourse long continued would make one thoroughly prosaic, hard,
and coarse. But the longest intercourse with Nature, though in her rudest moods, does
not thus harden and make coarse. A hard, sensible man whom we liken to a rock is
indeed much harder than a rock. From hard, coarse, insensible men with whom I have
no sympathy, I go to commune with the rocks, whose hearts are comparatively soft."

- Henry David Thoreau, November 15, 1853

If you turn the brightness up you can see that it's actually the rings intersecting the disc, not a moon.

EDIT: A shot that does show a moon, Titan alonside Saturn's right limb.

The bottom of the image was unfortunately clipped off on the spacecraft during readout.

Exquisite image.

It's interesting though how much 'noise' there is in the image, it appears they have barely 50% of the frame to work with...see attached image of W00016082 with the gamma correction turned way up. Do they use a mask of some sort to clean the lens smears and such?

Thanks Doug, is that the e-ring showing up in the first?

Umm, i think something might have gone a little wrong with the second. i was thinking more like stiching this and this image.

That would be a blue image on the left and a methane band ( I think ) filter on the right. I did try the methane band images, but they have been 2x2 downsampled sad.gif

Ah - you mean like this.

Pity the more exotic filters are down-sampled - but hey - we get what we get smile.gif
