So there seems to be moving ice on Pluto, signs the planet is geologically active. It too cold to be water ice, but isn't too cold to be nitrogen ice. But regardless this means its not a dead hulk of a planet bobbing around on the edge of the solar system. Its active.
It also means, though we won't know for a bit, that the planet may have an ocean beneath the ice. If there is something moving on the surface, there's a good chance there is something moving beneath.
And who knows, there may be life down beneath that crust.
And if not, come a few billion years form now, when the sun expands, devouring Earth, Pluto may warm enough to allow life to thrive.
