Two Small Pluto Moons Get Their Close-Ups (Photos)

Pluto's small moons are starting to come out into the light. The most jaw-dropping photos captured by NASA's New Horizons spacecraft during its historic July flyby of Pluto depict the dwarf planet or its largest moon, Charon. "Nix isn't very large, and there is a very fine line between an impact that will make a crater that big and one that will break Nix apart," New Horizons team member Simon Porter, of the Southwest Research Institute in Boulder, Colorado, wrote in a blog post last week.
