Rhea in unprecedented detail

While all the attention of the last few days has justifiably focused on the Huygens lander and the images from Titan, the Cassini probe itself has been busy as well.

On Sunday (16 January) Cassini captured a sequence of images of Saturn's moon Rhea, revealing unprecedented detail of surface of this moon. One intriguing feature is the long bright linear feature that crosses the moon towards the bottom of the images.

This image is the result of stacking five raw Cassini images (N00026544.jpg to N00026550.jpg) using the excellent freeware astronomical imaging program Registax 3. The final image was adjusted to emphasise the details on the surface.
