Ok, are you ready for this? I know... WOW.

This swirling maelstrom of clouds is what was seen over Saturn's earlier today, November 27, by 's . This is a raw image, acquired in polarized light, from a distance of 238,045 miles (383,097 kilometers)… all I did was remove some of the hot pixels that are commonly found on Cassini images taken with longer exposures.

Again… WOW.

My attempt at a color composite can be seen below, plus another treat:

It's rough, and a little muddy because the clouds were moving between image channels (not to mention the blue channel image was rather underexposed) but here's a color-composite of the same feature, made from images taken from a slightly :

Pretty darn cool… Cassini does it yet again!

The images above show a central vortex at Saturn's north pole. Saturn is also known to have a long-lived hexagonal jet stream feature around its north pole as well, but that is not shown in those images as it runs along a lower latitude. Instead, you can see that HERE:

Captured with wider angle in this image the structure can be made out  as well as the vortex, which sits at the center just over the pole. Saturn's hexagon is about 25,000 km (15,500 miles) in diameter… large enough to fit almost four Earths inside. This image was also acquired today.

An RGB composite of this feature is below:

I'll let this all sink in a bit until more information is available.
