The bladed terrain of Pluto’s Tartarus Dorsa region, that were photographed by NASA's New Horizons spacecraft during its epic flyby in July 2015, as ice ridges 1,650 feet or so tall. On Earth, these structures rise just a few feet above the ground in cold, mountainous regions of Earth.
The gargantuan size is predicted by the same theory that explains the formation of these features on Earth.
On Earth however the structures are made up of snow or water ice, whereas Pluto's ridges are mostly methane and nitrogen ices.
Researchers say that Pluto's structures probably formed within the past few tens of millions of years.
