The New Horizons science team is starting to release some of the imagery returned post-flyby. There are processed Science Gallery images, as well as a new dump of raw(er) LORRI images.
The money shot for me is a gigantic mosaic of the highest-rez images (spherical mosaic). I won't reproduce it here because it's a monitor-buster, but ya gotta. You just gotta.
Here's one of the raw images making up the big mosaic:
The big mosaic shows this as the margin (damn I want to say "shore") of a huge patch of white...can I say "frozen lake"? I think I can because of the polygonal cracks. That there is a solid sign of convection, as I understand things. Some fluid flowed underneath that solid surface at some time in the fairly recent past. That's really cool. But not absolute zero cool.
Enjoy.
Psst! Pluto pictures! Getyer Pluto pictures here!
