This summer, the New Horizons probe flew past Pluto at 14km/second, but in the meantime managed to beam pack to Earth some amazing scientific data, but also high-res photos. This includes this amazing shot showcasing the transition from mountains to plains on the dwarf-planet.  On the left is al-Idrisi Montes, mountainous highlands thought composed primarily of blocks of solid nitrogen.
