The "Death Star" Moon: Mimas



The official NASA caption is "That's no space station."

I guess relating to this thread it means we are in the Star Wars universe after all.

Purple haze all in my brain
Lately things just don’t seem the same
Actin' funny, but I don't know why

Thanks Jimmy! 8) [Beats Purple Rain ]

It is intriguing that the Rayleigh scattering is only in the upper and, I suppose, lower atmosphere. This seems surprising to me. A rough guess would be only the upper regions have the smaller molecules (thanks in part to the molecular break-down the article discussed) allowing the scattering. Large molecules do not allow much scattering of shorter wavelength light.

Here is an animation of what I'm pretty sure is Saturn's south pole:

The Sky at Night: Moons of Saturn

If you missed it on TV, you can now watch it online! (Well, sort of. RealOne Player, or such-like, required.)

Was there a Cassini update on NASATV today? There was something scheduled for 1pm EDT but I was out at the time.

OUT FROM THE SHADOWS: TWO NEW SATURNIAN MOONS

Quote:
With eyes sharper than any that have peered at Saturn
before, the Cassini spacecraft has uncovered two moons, which
may be the smallest bodies so far seen around the ringed
planet.

The moons are approximately 3 kilometers (2 miles) and 4
kilometers (2.5 miles) across -- smaller than Boulder, Colo.
edit: That brings the total to 33, I believe. The article doesn't mention the total, and I haven't looked it up in a while, but I keep a running total of the solar system's moons on my desktop and at last count I had Saturn with 31.

You're correct. Satellite discoverer Scott Sheppard's site has up-to date information on giant planet satellites.

I'm sure this was discussed before: At which size they will stop to call these rocks 'moons'?

Currently there is not any official lower limit.

Looks like the Cassini Picture of the Day on the Cassini homepage haven't been updated...
