            "description": "Over three and a half billion miles from the Sun, Pluto is too cold for liquid water to exist on its surface. Its interior however, may tell a different story. NASA research suggests that Pluto—and other small, icy bodies—may in fact be storing oceans of water beneath their surfaces, kept liquid by a process called tidal heating. Tidal heating occurs when orbiting bodies, such as Pluto and its largest moon, Charon, create heat due to the constant pulling of gravity between the bodies. An analysis of the light reflected from icy worlds in the outer solar system, including Pluto, reveals signatures of crystalline water ice and ammonia hydrates. At the extremely low surface temperatures on these objects, water ice takes a disordered, amorphous form instead of the regularly ordered crystals typical in warmer areas, such as snowflakes on Earth. Also, space radiation converts crystalline water ice to the amorphous form and breaks down ammonia hydrates, so they are not expected to survive long on the surfaces of these frozen worlds. This suggests that both compounds may have come from an interior liquid water layer that erupted to the surface, a process known as cryovolcanism. This discovery changes our understanding of where liquid water may form and opens up more options in the search for life within our solar system. Check out the images to learn more.",

            "description": "There is a pioneer hurtling through space. Its name is New Horizons, and in the summer of 2015, it will become the first spacecraft to visit Pluto. The dwarf planet lies at the edge of the solar system in a region known as the Kuiper Belt, a thick and icy expanse of space that is chock-full of objects yet to be explored or even discovered. Pluto and its moons Charon, Nix, and Hydra are particularly intriguing to astronomers, who have never had the chance to examine a dwarf planet up close. New Horizons left Earth in 2006, packed with two of each electronic system to protect against any mishaps on the long voyage ahead. It has traveled about one million miles every day since. Watch the video to learn more. || ",
