New images of Pluto's surface were released by NASA, revealing all sorts of terrain back-lit by a sunset. Yes, there are pictures of mountains, plains, and hazy skies illuminated by dusk. No likenesses to cartoon dogs this time, just beautiful, close encounters with the actual surface of the dwarf planet. These new images will be the muse for artists' renditions of planets, the kind that become screen savers and posters in stoners' bedrooms. Conspiracy theorists will no doubt scour the images for objects that look like aliens.
