Incredible pictures - you can see the ice evaporating into plumes off the side of the comet.

If I remember reading this story right the comet that the probe originally was supposed to go to disintegrated like that.

Nope. Periodic comets that make too many trips near the sun disintegrate.

Man, I love feeling nerdy once in awhile. I'm feeling like those Rush guys right about now. I think I'll go write a prog-rock tune about it.
