From The Travels of Cassini

Here’s sort of a throwback, one of Cassini’s great images newly processed.  The release title is “Translucent Arcs” and that is very descriptive. To me the image show the ring structure in terms of thickness density. Combined with the Sun-Saturn-Cassini angular configuration the rings seem to provide almost a “screen-door” effect to the scene.

This view is much different than what was published in 1622 by Fortunio Liceti in De Novis Astris et Cometis and much different than the sight from a backyard telescope.

Saturn is nothing short of breathtaking, if you’ve never seen it put it on your “bucket list” and look for suitable viewing opportunities — you might be surprised, local colleges and universities sometimes have public viewing and don’t overlook local astronomy clubs.

Here’s the caption from NASA:  Saturn’s rings are perhaps the most recognized feature of any world in our solar system. Cassini spent more than a decade examining them more closely than any spacecraft before it.

The rings are made mostly of particles of water ice that range in size from smaller than a grain of sand to as large as mountains. The ring system extends up to 175,000 miles (282,000 kilometers) from the planet, but for all their immense width, the rings are razor-thin, about 30 feet (10 meters) thick in most places.

From the right angle you can see straight through the rings, as in this natural-color view that looks from south to north. Cassini obtained the images that comprise this mosaic on April 25, 2007, at a distance of approximately 450,000 miles (725,000 kilometers) from Saturn.

The Cassini spacecraft ended its mission on Sept. 15, 2017.
