Weird 'Snakeskin' on Pluto Actually Similar to Features on Earth

Pluto's strange "snakeskin" terrain has an Earthly counterpart, a new study suggests. The "scales" of this alien landscape, which were first spotted by NASA's New Horizons spacecraft during its epic Pluto flyby in July 2015, are ice ridges 1,650 feet (500 meters) or so tall. "This gargantuan size is predicted by the same theory that explains the formation of these features on Earth," study lead author John Moores, of York University in Toronto, said in a statement.
