Possible Ice Volcanoes Discovered on Pluto

Ice Volcanoes on Pluto?  The informally named feature Wright Mons, located south of Sputnik Planum on Pluto, is an unusual feature that's about 100 miles (160 kilometers) wide and 13,000 feet (4 kilometers) high. It displays a summit depression (visible in the center of the image) that's approximately 35 miles (56 kilometers) across, with a distinctive hummocky texture on its sides. The rim of the summit depression also shows concentric fracturing. New Horizons scientists believe that this mountain and another, Piccard Mons, could have been formed by the 'cryovolcanic' eruption of ices from beneath Pluto's surface.

The possible discovery of a pair of recently erupting ice volcanoes on Pluto are among the unexpected “astounding” findings just unveiled by perplexed scientists with NASA’s New Horizons spacecraft, barely four months after the historic first flyby of the last unexplored planet in our solar system.

“Nothing like this has been seen in the deep outer solar system,” said Jeffrey Moore, New Horizons Geology, Geophysics and Imaging team leader from NASA Ames Research Center, Moffett Field, California, as the results so far were announced at the 47th Annual Meeting of the Division for Planetary Sciences (DPS) of the American Astronomical Society (AAS) this week in National Harbor, Maryland.

“The Pluto system is (…)
