The image data from E-20 began arriving on Earth on Thursday, Oct. 15 (which also happened to be the 18th anniversary of Cassini's launch) and I particularly liked the one below. Crescent-lit by the Sun, Enceladus' night side is seen bathed in the dimmer glow of reflected light from Saturn. Visible at the center is the 6.5-mile (10.4-km) -wide Bahman crater, surrounded by a wrinkled plain of ridges in an otherwise crater-free terrain.
ANALYSIS: Enceladus Spreads Ghostly Ice Tendrils Around Saturn
Recent findings from the Cassini mission have confirmed the presence of a subsurface ocean sandwiched between its icy crust and rocky core - not pockets of water trapped in ice, not a localized underground reservoir, but a full global ocean similar to Europa's. This discovery further strengthens the case for Enceladus as a possible host to extraterrestrial life.

"Enceladus fascinates us because of a sub-surface, global ocean, lying a few tens of miles beneath its surface, that is actively venting into space," wrote Cassini imaging team leader Carolyn Porco on Oct. 15. "And though this magnificent mission, that left Earth 18 years ago today, is not yet over, we are already looking forward to the time, hopefully not too far in the future, when we can travel back to Enceladus with the express purpose of answering the question that burns in all of us: Could there be life under its cracked and cratered surface?"
