A moon emerging from a moon

Here’s a nice picture of one of Saturn’s moons (Enceladus) emerging from behind another one (Dione) or perhaps it’s starting to disappear behind it. Anyway there’s some moons (Credit: NASA/JPL-Caltech/Space Science Institute):

Enceladus’ plume and a poem

To get a better of what is in the plume that’s spews out of Saturn’s moon Enceladus (it’s known to contain water vapor, sodium, and organic molecules), they sent Cassini through it on November 2, 2009. Here’s a picture of the plume (Image Credit: NASA/JPL/Space Science Institute–click on it to see it better):

And since today is Friday, a poem (there might not be a poem next week):

What should I do
Run ragged to the world
Grasp a pearl in my hand
Or feign indifference?

Enceladus, water, and a poem

It seems that a moon of Saturn has salt water in it:

For the first time, scientists working on NASA’s Cassini mission have detected sodium salts in ice grains of Saturn’s outermost ring. Detecting salty ice indicates that Saturn’s moon Enceladus, which primarily replenishes the ring with material from discharging jets, could harbor a reservoir of liquid water — perhaps an ocean — beneath its surface.

So here’s a picture of Enceladus showing the jets of water in false color (all of the images are from: NASA/JPL/Space Science Institute):

and here’s another image of water jetting out:

and here’s a picture of the moon itself:

Enceladus-PIA11133

and one more where it’s just behind another of Saturn’s moons, Dione, and showing (free trivia bit) that it’s the solar system’s most reflective body (returning 99% of the visible light that strikes it):

Finally here’s a poem that celebrates something, potato chips I think:

A jump in the dark
It’s coming after me
Hope and hurt drown my brain
As I see the cat.

Can’t you hear it
The doubt in your soul
As myriad life goes by
But seems like none of that.
