This week's best images of Pluto and its moons

NASA released another round of amazing Pluto images this week taken by the New Horizons spacecraft. We now have closeups of Pluto's smaller moons Nix and Hydra, as well as the best high-resolution images of Pluto we're going to get from this mission. We also know more about the dwarf planet's icy heart, as well as a second mountain range on the edge of one of its dark equatorial regions.

These are the last images we'll have of Pluto for a while. NASA needs time to downlink the bulk of the data collected by New Horizons so far, and that's going to take a couple months. So we'll have more goodies from the spacecraft sometime in September. Let these images whet your appetite until then.
