It it mind-blowing to think that Pluto may be geologically active enough to have produced that type of landscape.
The question is how. Does it’s system of moons really exert tidal forces strong enough to cause interior heat? Or is it seriously possible that it has a heated core?
And this just came to me. One theory is that Pluto used to be a moon of Neptune. It may very well have been one until very recently to produce those features through tidal forces from Neptune. At some point it then got knocked off into its present orbit.
This was discussed at the nasa presser today and the short answer is no. They were pretty excited about that, too. I think you can watch it in repeat at http://www.nasa.gov/multimedia/nasatv/.
