Animation of Dark Beads in Saturn’s Ionosphere

This video of Saturn’s ionosphere highlights the contrast in brightness between JWST’s infrared observations of the aurora and the dim bead features. The aurora itself is relatively weak, almost impossible to image from Earth, needing hours of integration time to observe using ground-based data. However, the auroral features are at least four times brighter than the brightest parts of the dark bead features, so to properly show the hidden features, the aurora are completely saturated.
