Enceladus, Saturn's Europa
Cassini recently made its first close flyby of Enceladus, and the first images are back: Here is the great high-resolution photomosaic and here are some more images. I cannot tell you, my readers, what joy these pictures bring to my eyes. They remind me of seeing Triton or Miranda or Gaspra for the very first time close up. Enceladus is Saturn's Europa or Miranda--the tortured icy moon with the fresh young surface, tightly packed with regular ripples of folded ridges.
