Another great view of Saturn—and how it'll look in 100 million years

Please excuse the double Saturn with cheese posting today but this stunning composite image of the ringed world—as seen from the top—is too good not to mention here.

It was made with 36 photos taken by Cassini on October 10 and it shows the planet as you would see it from an orbiting spaceship.

Jason Kottke removed the rings because he's mean like that. Notice how the sunlight bounced off the rings disappear, making it a much duller planet.

Incidentally, this is how Saturn will look in a hundred million years, when all the rings disappear.

This stunning view of Saturn will restore your sense of wonder

Not since the release of this beautifully backlit view of Saturn have we found ourselves so arrested by an image of the ringed planet. Which, for a celestial body as consistently photogenic as Saturn, is truly saying something.

"On October 10th, [the Cassini spacecraft's] wide-angle camera captured a set of 12 RGB footprints [36 photos total, acquired with red, green and blue filters which, when combined, approximate true color] covering Saturn and the rings," writes Gordan Ugarkovic, who created the image, in a comment thread over at Unmanned Spaceflight. He continues: "Here's an attempt at compositing that data into a mosaic. It's not geometrically accurate, but I tried coaxing the data into at least looking nice."

"Looking nice" my foot; this image is absolutely spellbinding – a view of Saturn unlike any we've ever seen. According to his profile page at The Planetary Society, Ugarkovic is a Croatian software developer who moonlights as an astrophotographer and "dabbles" in planetary image processing – a description that actually made me laugh aloud when I read it, because, well, frankly, does this look like the work of a dabbler to you? (By the way: If you're not viewing this image at full, 4000 x 3200 resolution you're doing yourself a grave disservice.)

No. The answer is "no." In fact, over at Bad Astronomy, Phil Plait just called this his favorite image of Saturn ever. Here's why:

The detail is incredible. Cassini was high above Saturn to the north, looking “down” on the ringed world when it took these images. You can see the bizarre hexagonal north polar vortex, the six-sided jet stream flowing around Saturn. The subtle but beautiful bands mark the cloud tops of Saturn’s atmosphere. Unless I'm mistaken, the thin white line you see wrapping around the planet at mid-latitude is the remnant of a vast stormso huge it completely dwarfed our own home world of Earth. And if you look carefully (you can measure it!) you can see that Saturn is highly flattened, its equatorial diameter wider than through the poles.

And that's just for starters. The rings, seen here from above rather than edge-on, appear far more circular than usual, their grooves, gaps and gradients presented in all their annular glory. The planet's north polar vortex – hexagonal in shape and an ethereal, spumy hue – is clearly seen from this angle. (NB: Image processor Val Klavans has also produced a close-up composite image of the hexagon, created with raw images collected by Cassini during the same October 10th flyby, to be featured in the forthcoming IMAX film In Saturn's Rings.) Also visible are the moons Pandora and Prometheus, near the one and two o'clock positions, respectively. As Emily Lakdawalla notes over the Planetary Society Blog, it's "a view never possible from Earth."

Color us very, very impressed. Hats off to the Cassini team for composing this remarkable shot, and to Ugarkovic for assembling the raw images into this stunning composite. Word has it CICLOPS, Cassini's imaging team, is working on a jaw-dropping composite image of its own, to be released any day now; not that we doubt their abilities, but Ugarkovic's will surely be a tough act to follow. We can't wait to see what they come up with.

Many thanks to Emily Lakdawalla, Gordan Ugarkovic and The Planetary Society for bringing this image to our attention, and allowing us to share it with you here!
