Icy volcanoes may lie on the southern rim of Pluto's frozen heart. Images from NASA's New Horizons spacecraft have identified two peaks that tower nearly 4 miles high over the surface of the dwarf planet, and scientists say the peaks' physical features suggest they might be volcanoes. Oliver White, a New Horizons postdoctoral researcher with NASA's Ames Research Center in California, said on Monday, "These are two really extraordinary features. Nothing like this has ever been seen in the solar system." As of now, Scientists don't yet know what could be generating the heat inside Pluto necessary to create a volcano on the surface. www.space.com/31073-pluto-ice-volcano-mountains-photos.html www.wochit.com This video was produced by Wochit using wochit.com
