Pluto Pix Push Interest in Space ExplorationPhotos transmitted from 4 billion miles away by NASA's New Horizons Pluto space probe have sparked fresh interest in space exploration.

A close-up image of a region near Pluto's equator shows mountains reaching 11,000 feet in height. The lack of craters suggests they're relatively new.
