Cassini Mission Highlight: Mile-High Spikes Along Saturn’s B Ring

A field of spike-like structures rise up over two miles from the outer edge of Saturn’s B ring in the amazing image above, captured by Cassini during Saturn’s spring equinox in August 2009. These pointy perturbations are caused by the gravitational nudges of tiny (~1/2 mile) embedded moonlets traveling around Saturn within the B ring, causing fine icy…

Have Waves Finally Been Found on Titan’s Lakes?

We’ve known for quite some time now that lakes of liquid methane and ethane exist on the frigid surface of Saturn’s overcast moon Titan. While the sheer presence of large amounts of liquid on another world is fascinating, one thing that’s particularly intrigued scientists about these hydrocarbon lakes is their uncanny stillness — in many…

Good Vibrations

Dynamic spike-like structures along the edges of Saturn’s rings are caused by oscillations of material that mimics the behavior of our entire galaxy…in other words, Saturn’s rings are a miniature version of the Milky Way! Along the outer edge of the dense B ring Cassini mission scientists have observed ring particles rising above the ringplane…

Ring Racer

Man, I just LOVE this stuff. 🙂 This has to be one of the coolest images yet of one of my favorite subjects: Saturn’s moon Daphnis casting a shadow and riling up the rings as it travels along the 26-mile-wide Keeler Gap, a channel it keeps clear around the outer edge of the A ring….

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,…
