The Hubble Space Telescope shows Saturn with the rings edge-on and both poles in view, with both of its fluttering auroras visible.

A Cassini scientist explains the flickering “northern lights” high above Saturn, shown for the first time in a visible-light movie.

Recent data from NASA’s Cassini spacecraft show that the variation in radio waves controlled by the planet’s rotation is different in the northern and southern hemispheres. These two radio waves, converted to the human audio range, can be heard in a new video:


The signal variations — which are controlled by the planet’s rotation — also change dramatically over time, apparently in sync with the Saturnian seasons.
