I swear I started one of these threads (or that someone else did), but I can't find it.

Some new images coming back from the Cassini mission

I'm still trying to conceptualize this one

The moon is passing inside the arc of a ring. As it glides by, it pulls particles from the ring towards it.

@littlek,
How does the moon in the first picture compare to the size of our moon? I can't imagine its particularly large... about the size of a comet or asteroid?

That moon is Prometheus, a "potato-shaped" moon. It is about 145 by 85 by 62 km in size. The diameter of the Moon is 3,474 km.

Prometheus is really small.

@littlek,
I think what you may be referring to, Miss Kay, is that pictures from Cassini have been posted in threads that are not specifically about Saturn.

Thanks for this thread--i love this stuff.

I love that video of ripples. The second moon (outside the arc) smooths the damage done by the first (inside the arc).

Region - how could I have searched for 30 minutes and not found it? Did you just add the tags?

@littlek,
I think you posted it on a thread and then I, in turn, posted it on the ID thread. So it needs to have it's own discussion! There's an astronomy test posted on Facebook I'll link to later on. It's kinda fun but even though it's 20 questions, it's more like 25 or 26 as the fourth choice is whether the first two or three apply!

@Lightwizard,
I took that test and didn't do all that well.

@littlek,
I found it and then had to go on errands. Don't feel badly -- I only got 14, but I take tests like that on a lark and do them quickly, not giving enough time to think it out or pull something out of my memory. Most of it are discoveries based on the Hubble.

I know who my Facebook A2K screen names are and then they slip by me but in my book, you're a star!

@Setanta,
I also love this stuff -- anxiously awaiting all the new Hubble photos with the new camera. The NOVA special on the repair was outstanding. I was as close to going into astronomy as I was going into architecture in the last year of college and, unfortunately, I got a job with a friend of the family's job as their controller, so it never came to pass. I have to admit it was salary greed.

More photos of Saturn (30 of them)....

This could be an artist's scifi book cover.

Saturn looks as though it were a product of some science fiction writer's mind.
