Default Cassini and Saturn

I'll reserve this thread for reports on Cassini's observations of Saturn itself (as contrasted with the rings or moons).

South Pole on Saturn

Quote:
Details observed in Saturn's south polar region demonstrate that this area is far from featureless.

frankly, I'm finding the new images from Saturn more refreshing than the random rocky landscapes of Mars. That there is a wicked image of Saturn's south pole...

Looks like new raw images of Saturn's south pole has been released (from July 13th).
They have much higher resolution, like this one.

Here is an animation of Saturn's rotation. It was made with three very recent wide angle camera images, all three taken through the RED filter. The only obvious sign of movement is a white spot, presumably a storm, moving from left to right.

Saturn's Southern Bullseye

Quote:
Saturn's southern polar region exhibits concentric rings of clouds which encircle a dark spot at the pole. To the north and toward the right, wavy patterns are evident, resulting from the atmosphere moving with different speeds at different latitudes. A surprising feature of Saturn's magnetic field is that the magnetic pole appears to lie exactly atop the north and south geographical poles. This is unlike Earth and Jupiter where there is a large tilt between the planet's axis and the dipole axis, meaning that Earth's magnetic north is not located at the north pole.

Default Weird lightning

Sporadic lightning near the equator of Saturn.

And they say our climate is weird. Try one where the hottest regions are right next to parts that are shaded by the rings and are hence very cold.

Also, a low hanging radiation belt has been discovered.

Original press release:

Saturn's Shadow and Titan's Glow Shed Light on a Complex System

Quote:
The Cassini spacecraft, which began its tour of the Saturn system just over a month ago, has detected lightning and a new radiation belt at Saturn, and a glow around the planet's largest moon, Titan.

Saturn's active atmosphere

Quote:
This image of Saturn's southern pole was taken by Cassini on July 13, when the spacecraft was 5.1 million km (3.2 million miles) away from the planet. It was taken using a filter sensitive to infrared light, and shows swirls and fingers of clouds racing around the pole. The dark spot surrounded by concentric rings of clouds marks the south pole.

Spectrum of Stormy Saturn

Quote:
Seeing Saturn in different wavelengths gives mission scientists a new and stormy picture of weather on the gas giant. While the view in ultraviolet highlights the stratosphere, the view in infrared shows swirling patterns from rotating cloud bands.

South polar storms on Saturn spotted by Cassini

Quote:
This Cassini spacecraft narrow angle camera view of Saturn's southern polar region features a bright white spot, or storm, surrounded by faint, darker swirls of clouds.

Most detailed look to date at the temperature of Saturn's rings.

Those rings are surreal...

[quote="ToSeek"]I'll reserve this thread for reports on Cassini's observations of Saturn itself (as contrasted with the rings or moons).

South Pole on Saturn

I'm doing research on Cassini images of Jupiter and I just saw these pictures. There's a similar division in Jupiter's north pole that may be indicative of deeper structures. As I search for it myself, I'm wondering if anyone knows the camera used to take this pic or what latitude the rings starts at because with this info I can see if they are related to the Jovian structure. Any help would be greatly appreciated.

The Photojournal page is here. It was taken with Cassini's narrow-angle camera. It doesn't seem to be in the PDS yet (unsurprisingly), so there's not much more information right now.

Thanks. This will definitely get me started, but I'd really kill for a heads on a polar image.

I don't think Cassini's orbit can oblige you there.
