Pluto Ice Volcano

January 14, 2016 -NASA released spectacular images of possible ice volcanoes on the surface of Pluto. Captured on July 14, 2015 by New Horizons Long Range Reconnaissance Imager (LORRI), geologists are suggesting evidence of cryovolcanic activity. Pictured below is Wright Mons (named by New Horizons mission in honour of the Wright brothers ) Science is intrigued by absence of impact craters (only one crater in vicinity of Wright Mons ) indicating a surface/crust of recent formation.

Eruption is the single characteristic ice volcano shares with earthly volcanic perception. Rather than molten rock, cryo eruption spews a sludge of water, ice, nitrogen, ammonia and methane. Jeffrey Moore, leader of New Horizons Geology, Geophysics and Imaging team believes proof of volcanic Pluto will unlock clues to geologic and atmospheric evolution.

Sprinkled across the LORRI mosaic is enhanced color data from the Ralph/Multispectral Visible Imaging Camera (MVIC), from a range of 21,000 miles (34,000 kilometers) and at a resolution of about 2,100 feet (650 meters) per pixel. The entire scene is 140 miles (230 kilometers) across. Credits: NASA/JHUAPL/SwRI

Using New Horizons images of Pluto’s surface to make 3-D topographic maps, scientists discovered that two of Pluto’s mountains, informally named Wright Mons and Piccard Mons, could be ice volcanoes. The color depicts changes in elevation, blue indicating lower terrain and brown showing higher elevation. Green terrains are at intermediate heights. Image credit: NASA/JHUAPL/SwRI

Closer Look: Majestic Mountains and Frozen Plains: Just 15 minutes after its closest approach to Pluto on July 14, 2015, NASA’s New Horizons spacecraft looked back toward the sun and captured this near-sunset view of the rugged, icy mountains and flat ice plains extending to Pluto’s horizon. The smooth expanse of the informally named Sputnik Planum (right) is flanked to the west (left) by rugged mountains up to 11,000 feet (3,500 meters) high, including the informally named Norgay Montes in the foreground and Hillary Montes on the skyline. The backlighting highlights more than a dozen layers of haze in Pluto’s tenuous but distended atmosphere. The image was taken from a distance of 11,000 miles (18,000 kilometers) to Pluto; the scene is 230 miles (380 kilometers) across. View larger. | Image credit: NASA/JHUAPL/SwRI)
