I'm interested to find that it isn't just a uniform ball of ice, it seems to have some geographical locations. I also think it's interesting that is has snow made of nitrogen, and they've seen a tar substance made of nitrogen also.
Looks different than how my science textbooks back in school depicted it, lol. I'm totally excited we are finally getting decent pictures of it, there has been so many chages on Pluto's status over the decades.
