Enceladus is alive!

It's official: Enceladus has joined the rarefied community of Solar System objects that have been caught in the act of making new geology. The only other members of the club are Earth and Io. A whole slew of observations have come together from different Cassini instruments to make this conclusion:

I've added all the relevant data to my Enceladus-11 Flyby page, so go check it out! The CIRS hot spot data is at left. I have also just spoken with Cassini Deputy Project Scientist Linda Spilker. She is thrilled about these Enceladus discoveries, and filled me in about how the discoveries came together. I'll be writing up a news story on all of this.

Congratulations to everyone on the Cassini science teams! And kudos, too, to the navigators, for coming up with a trajectory for Cassini that took it so close to Enceladus, only 173 kilometers above the surface! And thanks to Jason at Titan Today for being so quick to post the new data as soon as it was released!
