An enhanced-color view of Pluto shows a region where warm material bubbles up from below, forming new crust. Scientists with the New Horizon mission, which flew past Pluto on July 14, 2015, compare the process to a lava lamp, with large blobs of material moving to the surface while others sink back below the crust. This image spans about 250 miles. [NASA/JHUAPL/SWRI]
