Rings in Relief

This wide-angle view from Cassini, taken on August 16 (2009), shows an amazing amount of relief across the surface of Saturn’s A ring as well as a long shadow cast by the wake of the shepherd moon Daphnis within the Keeler gap. 4.3-mile-wide Daphnis, almost too small to be seen here, sculpts the edges of…

Sunday Best

Another fantastic image of one of my favorite subjects from the Cassini mission: the little shepherd moon Daphnis and its icy wake within the Keeler gap. This is an adjusted version of a raw image taken Saturday, July 11, and received at the imaging center in Boulder, CO later the same day. See the original…

Out of the Shadows

A stunning image by Cassini, received today, of Daphnis splashing through the Keeler Gap (as seen in my last post). In this photo the sunlight is coming from the opposite direction though. Saturn’s massive shadow falls upon the rings on the right side of this image. Background stars can be seen through the rings. From…

Wave Forms

Cast shadows reveal some interesting structure in the waves sent up by little Daphnis in this image, taken by the Cassini spacecraft on June 26, 2009. Daphnis orbits Saturn within the 26-mile-wide Keeler gap in the A ring. Its gravity disrupts the edges of the gap, carving scalloped edges in the ring material and also,…

Little Sculptor

  Another great raw image from the Cassini orbiter, showing the shepherd moon Daphnis raising high-crested waves in the edges of Saturn’s A ring bordering the Keeler Gap. Shadows cast by the low-angle sunlight show the height of these sinuous disturbances. Daphnis’ gravity affects the ring material both in front of it and behind. Discovered…

Ripples Have Ridges

  Another great image showing Saturn’s moon Daphnis sending up high-walled waves in the ring material edging the Keeler Gap in which it resides. The waves cast shadows back onto the A ring, as does the moon itself. This image was taken on May 24, 2009 by the Cassini spacecraft. RAW image: NASA/JPL/Space Science Institute

Wave Rider

  4.3-mile-wide Daphnis races along its track, the 26-mile-wide Keeler Gap in Saturn’s A ring, stirring up sinuous edge waves in the ring material behind and before it. Not only does the shepherd moon cast a small shadow onto the ring, but so do the crests of the waves it’s creating! It’s a wonderful little…

Making Waves

  Little Daphnis sends waves curling in its wake as it courses along the Keeler Gap in Saturn’s A-ring in this photo from Cassini’s narrow-angle camera. The image was taken on January 31, 2009, approximately 532,000 miles from Daphnis and the rings. Daphnis is about 5 miles in diameter. The Keeler Gap is 26 miles…
